A galley is a type of ship optimised for propulsion by . Galleys were historically used for naval warfare, trade, and piracy mostly in the seas surrounding Europe. It developed in the Mediterranean world during antiquity and continued to exist in various forms until the early 19th century. It typically had a long, slender hull, shallow draft, and often a low freeboard. Most types of galleys also had sails that could be used in favourable winds, but they relied primarily on oars to move independently of winds and currents or in battle. The term "galley" originated from a Greek term for a small type of galley and came in use in English from about 1300. It has occasionally been used for unrelated vessels with similar military functions as galley but which were not Mediterranean in origin, such as medieval Scandinavian , 16th-century Acehnese ghalis and 18th-century North American gunboats.
Galleys were the primary warships used by the ancient Mediterranean naval powers, including the , Ancient Greece and ancient Rome. The galley remained the dominant type of vessel used for war and piracy in the Mediterranean Sea until the start of the early modern period. A final revival of galley warfare occurred during the 18th century in the Baltic Sea during the wars between Russian Empire, Sweden, and Denmark-Norway. In the Mediterranean, they remained in use until the very end of the 18th century, and survived in part because of their prestige and association with chivalry and land warfare. In war, galleys were used in landing raids, as troop transports and were very effective in amphibious warfare. While they usually served in wars or for defense against piracy, galleys also served as trade vessels for high-priority or expensive goods up to the end of the Middle Ages. Its oars guaranteed that it could make progress where a sailing ship would have been , and its large crew could defend it against attacks from pirates and raiders. This also made it one of the safest and most reliable forms of passenger transport, especially for Christian pilgrims during the High and Late Middle Ages.
For naval combat, galleys were equipped with various weapons: naval ram and occasionally until late antiquity, Greek fire during the Early Middle Ages, and from the 15th century. However, they relied primarily on their large crews to overpower enemy vessels through Naval boarding. Galleys were the first vessels to effectively use heavy gunpowder artillery against other ships and naval fortifications. Early 16th-century galleys had heavy guns in the bow which were aimed by manoeuvring the entire vessel. Initially, gun galleys posed a serious threat to sailing warships, but were gradually made obsolete by the development of with superior broadside armament. Galleys were unsuitable in the wider ocean, far from land and bases of resupply. They had difficulty in rough weather. Their role as flexible cruisers and patrol craft in the Mediterranean was also taken over by and other oar-sail hybrids.
Oars on ancient galleys were usually arranged in 15–30 pairs, from monoremes with a single line of oars to with three lines of oars in a tiered arrangement. Occasionally, much larger polyremes had multiple rowers per oar and hundreds of rowers per galley. Ancient shipwrights built galleys using a labour-intensive, shell-first mortise and tenon technique up until the Early Middle Ages. It was gradually replaced by a less expensive skeleton-first carvel method. The rowing setup was also simplified and eventually developed into a system called alla sensile with up to three rowers sharing a single bench, handling one oar each. This was suitable for skilled, professional rowers. This was further simplified to the a scaloccio method with rowers sharing a bench but using just a single large oar, sometimes with up to seven or more rowers per oar in the very largest war galleys. This method was more suitable for the use of forced labour, both and Penal labour. Most galleys were equipped with sails that could be used when the wind was favourable: basic until the Early Middle Ages and later lateen sails.
It was only from the Late Middle Ages that a unified galley concept started to come into use. Ancient galleys were named according to the number of oars, the number of banks of oars or rows of rowers. The terms are based on contemporary language use combined with recent compounds of Greek and Latin words. The earliest Greek single-banked galleys are called (from triakontoroi, "thirty-oars") and ( pentēkontoroi, "fifty-oars"). For later galleys with more than one bank of oars, the terminology is based on Latin numerals with the suffix -reme from rēmus, "oar". A monoreme has one bank of oars, a bireme two, and a trireme three. A human-powered oared vessel is not practically feasible as four or more oars to a bank will either interfere with each other, or be too high above the waterline to be practicable. In describing galleys, any number higher than three did not refer to banks of oars, but to additional rowers per oar. Quinquereme ( quintus + rēmus) was literally a "five-oar", but actually meant that there were more than one rower per oar in a bireme or trireme arrangement. For simplicity, many modern scholars refer to these as "fives", "sixes", "eights", "elevens", etc. Anything above six or seven rows of rowers was uncommon, but even an entirely unique "tessarakonteres" has been attested from the 3rd century BC. Any galley with more than three or four lines of rowers is often referred to as a "polyreme".
Medieval and early modern galleys were described based on the changing designs that evolved after the ancient designs and rowing arrangement had been forgotten. Among the most important is the Byzantine dromon, the predecessor to the Italian , the final form of the Mediterranean war galley. As galleys became an integral part of an advanced, early modern system of warfare and state administration, they were divided into a number of ranked grades based on the size of the vessel and the number of its crew. The most basic types were the large commander "lantern galleys", half-galleys, , , , and fregatas. Naval historian Jan Glete has described these as a sort of predecessor of the later rating system of the Royal Navy and other sailing fleets in Northern Europe.
The French navy and the Royal Navy built a series of "galley frigates" from around 1670–1690 that were small two-decked sailing cruisers with a single row of oarports on the lower deck, close to the waterline. The three British galley frigates also had distinctive names – James Galley, Charles Galley, and Mary Galley. In the late 18th century, the term "galley" was sometimes used to describe small oared gun-armed vessels. In North America, during the American Revolutionary War and other wars with France and Britain, the early US Navy and the navies they fought built vessels that were referred to "galleys" or "". These are today best described as brigantines or Baltic-style . The North American "galleys" were classified based on their military role, and in part due to technicalities in administration and naval financing. In the latter part of the 19th century, the Royal Navy term for the gig (a ship's boat optimised for propulsion by oar) reserved for the captain's use was "galley" even though it was issued to the ship by the navy dockyard as a "gig".
The first Greek galley-like ships appeared around the second half of the 2nd millennium BC. In the epic poem, the Iliad, set in the 12th century BC, oared vessels with a single row of oarmen were used primarily to transport soldiers between land battles. The first recorded naval battle occurred as early as 1175 BC, the Battle of the Delta between Egyptian forces under Ramesses III and the enigmatic alliance known as the Sea Peoples. It is the first known engagement between organized armed forces using sea vessels as weapons of war, though primarily as fighting platforms.
The Phoenicians were among the most significant naval civilizations in early classical antiquity, but little detailed evidence has been found of what kind of ships they used. The best depictions found so far have been small, highly stylized images on seals which illustrate crescent-shaped vessels equipped with a single mast and bank of oars. Colorful frescoes at the Minoan settlement on Santorini (about 1600 BC) depict vessels with tents arranged in a ceremonial procession. Some of the vessels are rowed, but others are paddled. This has been interpreted as a possible ritual reenactment of more ancient types of vessels, alluding to a time before rowing was invented. Little is otherwise known about the use and design of Minoan ships.
Mediterranean galleys from around the 9th century typically had 15 and 25 pairs of oars ("triaconters" and "", respectively) with just one level of oars on each side, or "monoremes". Sometime during the 8th century the first bireme galleys were built by adding a second level of rowers, one level above the other. This created a second bank of oars, adding more propulsion power with the same length of hull. It made galleys faster, more maneuverable and sturdier. Phoenician shipbuilders were likely the first to build two-level galleys, and bireme designs were soon adopted and further developed by the Greeks.
A third bank of oar was added by attaching an outrigger to a bireme. The outrigger was a projecting frame that gave additional leverage for a third rower to handle an oar efficiently. It has been hypothesized that early forms of three-banked ships may have existed as early as 700 BC, but the earliest conclusive written reference dates to 542 BC. These new galleys were called triērēs (literally "three-fitted") in Greek. Ancient Rome later applied the term triremis which is the origin of "trireme" and the name used most commonly today.
Most of the surviving documentary evidence comes from Greek and Roman shipping, though it is likely that merchant galleys all over the Mediterranean were highly similar. In Greek they were referred to as histiokopos ("sail-oar-er") to reflect that they relied on both types of propulsion. In Latin they were called Actuaria, "(ship) that moves", stressing that they were capable of making progress regardless of weather conditions. As an example of the speed and reliability, during an instance of the famous "Carthago delenda est" speech, Cato the Elder demonstrated the close proximity of the Roman arch enemy Carthage by displaying a fresh fig to his audience that he claimed had been picked in North Africa only three days past. Other cargoes carried by galleys were honey, cheese, meat, and live animals intended for gladiator combat. The Romans had several types of merchant galleys that specialized in various tasks, out of which the actuaria with up to 50 rowers was the most versatile, including the phaselus (lit. "bean pod") for passenger transport and the lembus, a small-scale express carrier. Many of these designs continued to be used until the Middle Ages.
After the fall of the Western Roman Empire around the 5th century AD, the old Mediterranean economy collapsed and the volume of trade went down drastically. The Byzantine Empire neglected to revive overland trade routes, but was dependent on keeping the sea lanes open to keep the empire together. In 600–750 AD bulk trade declined while luxury trade increased. Galleys remained in service, but were profitable mainly in the luxury trade, which set off their high maintenance cost. In the 10th century, there was a sharp increase in piracy which resulted in larger trade ships with more numerous crews. These were mostly built by the growing maritime republics of Italy which were emerging as the dominant sea powers, including Venice, Genoa, and Pisa. Their merchant galleys were similar to dromons, but without heavy weapons and both faster and wider. The largest types were used by Venice, based on galley types like the pamphylon and chelandion. They had tower-like superstructures and could be manned by crews of up to 1,000 men and could be employed in warfare when required. A further boost to the development of the large merchant galleys was the increase in Western European pilgrims traveling to the Holy Land. In Northern Europe, and their derivations, , dominated trading and shipping. They functioned and were propelled similar to the Mediterranean galleys, but developed from a separate building tradition.
In the Mediterranean, merchant galleys continued to be used during the High and Late Middle Ages, even as sailing vessels evolved more efficient hulls and rigging. The zenith in the design of merchant galleys came with the state-owned "" of the Venetian Republic, first built in the 1290s. The great galleys were in all respects larger than contemporary war galleys (up to 46 m) and had a deeper draft, with more room for cargo (140–250 tonnes). With a full complement of rowers ranging from 150 to 180 men, all available to defend the ship from attack, they were also very safe modes of travel. This attracted a business of carrying rich pilgrims to the Holy Land, a trip that could be accomplished in as little 29 days on the route Venice–Jaffa, despite landfalls for rest and watering, or to shelter from rough weather. Later routes linked ports around the Mediterranean, between the Mediterranean and the Black Sea, and between the Mediterranean and Bruges. In 1447 Florentine galleys could stop at as many as 14 ports on their way to and from Alexandria in Egypt.
The development of the naval ram sometime before the 8th century BC changed the nature of naval warfare, which had until then been a matter of boarding and hand-to-hand fighting. With a heavy projection at the foot of the bow, sheathed with metal, usually bronze, a ship could incapacitate an enemy ship by punching a hole in its planking. The relative speed and nimbleness of ships became important, since a slower ship could be outmaneuvered and disabled by a faster one. The earliest designs had only one row of rowers that sat in undecked hulls, rowing against thole pins, or oarports, that were placed directly along the railings. The practical upper limit for wooden constructions fast and maneuverable enough for warfare was around 25–30 oars per side. By adding another level of oars, a development that occurred no later than c. 750 BC, the galley could be made shorter with as many rowers, while making them strong enough to be effective ramming weapons.
The emergence of more advanced states and intensified competition between them spurred on the development of advanced galleys with multiple banks of rowers. During the middle of the first millennium BC, the Mediterranean powers developed successively larger and more complex vessels, the most advanced being the classical trireme with up to 170 rowers. Triremes fought several important engagements in the naval battles of the Greco-Persian Wars (502–449 BC) and the Peloponnesian War (431–404 BC), including the Battle of Aegospotami in 405 BC, which sealed the defeat of Athenian Empire by Sparta and its allies. The trireme was an advanced ship that was expensive to build and to maintain due its large crew. By the 5th century, advanced war galleys had been developed that required sizable states with an advanced economy to build and maintain. It was associated with the latest in warship technology around the 4th century BC and could only be employed by an advanced state with an advanced economy and administration. They required considerable skill to row and oarsmen were mostly free citizens who had years of experience at the oar.
The successor states of Alexander the Great's empire built galleys that were like triremes or biremes in oar layout, but manned with additional rowers for each oar. The ruler Dionysius I of Syracuse (–367 BC) is credited with pioneering the "five" and "six", meaning five or six rows of rowers plying two or three rows of oars. Ptolemy II (283–46 BC) is known to have built a large fleet of very large galleys with several experimental designs rowed by everything from 12 up to 40 rows of rowers, though most of these are considered to have been quite impractical. Fleets with large galleys were put in action in conflicts such as the Punic Wars (246–146 BC) between the Roman Republic and Carthage, which included massive naval battles with hundreds of vessels and tens of thousands of soldiers, seamen, and rowers.
The Roman galley fleets were turned into provincial patrol forces that were smaller and relied largely on liburna, compact biremes with 25 pairs of oars. These were named after an Liburnian known by Romans for their sea roving practices, and these smaller craft were based on, or inspired by, their vessels of choice. The liburnians and other small galleys patrolled the rivers of continental Europe and reached as far as the Baltic, where they were used to fight local uprisings and assist in checking foreign invasions. The Romans maintained numerous bases around the empire: along the rivers of Central Europe, chains of forts along the northern European coasts and the British Isles, Mesopotamia, and North Africa, including Trabzon, Vienna, Belgrade, Dover, Seleucia, and Alexandria. Few actual galley battles in the provinces are found in records. One action in 70 AD at the unspecified location of the "Island of the Batavians" during the Batavian Rebellion was recorded, and included a trireme as the Roman flagship. The last provincial fleet, the classis Britannica, was reduced by the late 200s, though there was a minor upswing under the rule of Constantine (272–337). His rule also saw the last major naval battle of the unified Roman Empire (before the permanent split into Western and Eastern later Empires), the Battle of the Hellespont of 324. Some time after the Battle of the Hellespont, the classical trireme fell out of use, and its design was forgotten.
In the eastern Mediterranean, the Byzantine Empire struggled with the incursion from invading Muslim Arabs from the 7th century, leading to fierce competition, a buildup of fleet, and war galleys of increasing size. Soon after conquering Egypt and the Levant, the Arab rulers built ships highly similar to Byzantine dromons with the help of local shipwrights from former Byzantine naval bases. By the 9th century, the struggle between the Byzantines and Arabs had turned the Eastern Mediterranean into a no-man's land for merchant activity. In the 820s Crete was captured by Al-Andalus Muslims who had fled a failed revolt against the Emirate of Cordoba, turning the island into a base for (galley) attacks on Christian shipping until the island was recaptured by the Byzantines in 960.
In the western Mediterranean and Atlantic, the division of the Carolingian Empire in the late 9th century brought on a period of instability, meaning increased piracy and raiding in the Mediterranean, particularly by newly arrived Muslim invaders. The situation was worsened by raiding Scandinavian who used longships, vessels that in many ways were very close to galleys in design and functionality and also employed similar tactics. To counter the threat, local rulers began to build large oared vessels, some with up to 30 pairs of oars, that were larger, faster, and with higher sides than Viking ships. Scandinavian expansion, including incursions into the Mediterranean and attacks on both Muslim Iberia and even Constantinople itself, subsided by the mid-11th century. By this time, greater stability in merchant traffic was achieved by the emergence of Christian kingdoms such as those of France, Hungary, and Poland. Around the same time, Italian port towns and city states, like Venice, Pisa, and Amalfi, rose on the fringes of the Byzantine Empire as it struggled with eastern threats.
During the 13th and 14th century, the galley evolved into the design that was to remain essentially the same until it was phased out in the early 19th century. The new type descended from the ships used by Byzantine and Muslim fleets in the Early Middle Ages. These were the mainstay of all Christian powers until the 14th century, including the great maritime republics of Genoa and Venice, the Papacy, the Hospitallers, Aragon, and Castile, as well as by various and privateer. The overall term used for these types of vessels was gallee sottili ("slender galleys"). The later Ottoman navy used similar designs, but they were generally faster under sail, and smaller, but slower under oars. Galley designs were intended solely for close action with hand-held weapons and projectile weapons like bows and crossbows. In the 13th century the Iberian Crown of Aragon built several fleet of galleys (known as Catalan galleys) with high castles, manned with Catalan crossbowmen, and regularly defeated numerically superior Angevin forces.
The sailing vessel was always at the mercy of the wind for propulsion, and those that did carry oars were placed at a disadvantage because they were not optimized for oar use. The galley did have disadvantages compared to the sailing vessel though. Their smaller hulls were not able to hold as much cargo and this limited their range as the crews were required to replenish food stuffs more frequently. The low freeboard of the galley meant that in close action with a sailing vessel, the sailing vessel would usually maintain a height advantage. The sailing vessel could also fight more effectively farther out at sea and in rougher wind conditions because of the height of their freeboard.
Under sail, an oared warship was placed at much greater risk as a result of the piercings for the oars which were required to be near the waterline and would allow water to ingress into the galley if the vessel heeled too far to one side. These advantages and disadvantages led the galley to be and remain a primarily coastal vessel. The shift to sailing vessels in the Mediterranean was the result of the negation of some of the galley's advantages as well as the adoption of gunpowder weapons on a much larger institutional scale. The sailing vessel was propelled in a different manner than the galley but the tactics were often the same until the 16th century. The real-estate afforded to the sailing vessel to place larger cannons and other armament mattered little because early gunpowder weapons had limited range and were expensive to produce. The eventual creation of cast iron cannons allowed vessels and armies to be outfitted much more cheaply. The cost of gunpowder also fell in this period.
The armament of both vessel types varied between larger weapons such as bombards and the smaller swivel guns. For logistical purposes it became convenient for those with larger shore establishments to standardize upon a given size of cannon. Traditionally the English in the North and the Venetians in the Mediterranean are seen as some the earliest to move in this direction. The improving sail rigs of northern vessels also allowed them to navigate in the coastal waters of the Mediterranean to a much larger degree than before. Aside from warships the decrease in the cost of gunpowder weapons also led to the arming of merchants. The larger vessels of the north continued to mature while the galley retained its defining characteristics. Attempts were made to stave this off such as the addition of fighting castles in the bow, but such additions to counter the threats brought by larger sailing vessels often offset the advantages of galley.
Attempts to combine the advantages of both rowing and sailing ships were done in the 16th century, resulting in . Despite their common name, their different types entailed different to one or another design. Venetian galleasses were particularly large and powerful galleys with hulls more akin to sailing ships, while in turn, Spanish Atlantic galleasses were essentially sailing ships fitted with a line of rows, which would be used strategically to assist maneuver and sprint while in battle.
Among these, Spanish admiral Álvaro de Bazán the Elder designed and built potent Atlantic to hunt down privateers. Spain also sent galley squadrons to the Netherlands during the Eighty Years' War which successfully operated against Dutch forces in the enclosed, shallow coastal waters. From the late 1560s, galleys were also used to transport silver to Genoese bankers to finance Spanish troops against the Dutch uprising. Mediterranean galleasses and galleys were part of an invasion force of over 16,000 men under Álvaro de Bazán the Younger that conquered the Azores in 1583. During this conquest, captain Diego de Medrano is noted for innovating naval warfare techniques by enhancing the design of his galleys, becoming the first person to successfully cross the ocean with this type of galley. Lá Armada for El Capitán de Navío
Outside European and Middle Eastern waters, Spain built galleys called to deal with pirates and privateers in both the Caribbean and the Philippines.
Heavy artillery on galleys was mounted in the bow, which aligned easily with the long-standing tactical tradition of attacking head on, bow first. The ordnance on galleys was heavy from its introduction in the 1480s, and capable of quickly demolishing the high, thin medieval stone walls that still prevailed in the 16th century. This temporarily upended the strength of older seaside fortresses, which had to be rebuilt to cope with gunpowder weapons. The addition of guns also improved the amphibious abilities of galleys as they could make assaults supported with heavy firepower, and were even more effectively defended when beached stern-first. An accumulation and generalizing of bronze cannons and small firearms in the Mediterranean during the 16th century increased the cost of warfare, but also made those dependent on them more resilient to manpower losses. Older ranged weapons, like bows or even crossbows, required considerable skill to handle, sometimes a lifetime of practice, while gunpowder weapons required considerably less training to use successfully. According to an influential study by military historian John F. Guilmartin, this transition in warfare, along with the introduction of much cheaper cast iron guns in the 1580s, proved the "death knell" for the war galley as a significant military vessel. Gunpowder weapons began to displace men as the fighting power of armed forces, making individual soldiers more deadly and effective. As offensive weapons, firearms could be stored for years with minimal maintenance and did not require the expenses associated with soldiers. Manpower could thus be exchanged for capital investments, something which benefited sailing vessels that were already far more economical in their use of manpower. It also served to increase their strategic range and to out-compete galleys as fighting ships.
Skillful usage of guns in galley warfare was seen in the Battle of the Gulf of Tunis, where Spanish and Italian galleys under Álvaro de Bazán y Benavides engaged and overwhelmed Barbary galleons thanks to the superior range of their own cannons.
No large all-galley battles were fought after the gigantic clash at Lepanto in 1571, and galleys were mostly used as cruisers or for supporting sailing warships as a rearguard in fleet actions, similar to the duties performed by outside the Mediterranean. They could assist damaged ships out of the line, but generally only in very calm weather, as was the case at the Battle of Málaga in 1704. They could also defeat larger ships that were isolated, as when in 1651 a squadron of Spanish galleys captured a French galleon at Formentera. For small states and principalities as well as groups of private merchants, galleys were more affordable than large and complex sailing warships, and were used as defense against piracy. Galleys required less timber to build, the design was relatively simple and they carried fewer guns. They were tactically flexible and could be used for naval ambushes as well amphibious operations. They also required few skilled seamen and were difficult for sailing ships to catch, but vital in hunting down and catching other galleys and oared raiders.
The last recorded battle in the Mediterranean where galleys played a significant part was at Matapan in 1717, between the Ottomans and Venice and its allies, though they had little influence on the outcome. Few large-scale naval battles were fought in the Mediterranean throughout most of the remainder of the 18th century. The Tuscan galley fleet was dismantled around 1718, Naples had only four old vessels by 1734 and the French Galley Corps had ceased to exist as an independent arm in 1748. Venice, the Papal States, and the Knights of Malta were the only state fleets that maintained galleys, though in nothing like their previous quantities.
While galleys were too vulnerable to be used in large numbers in the open waters of the Atlantic, they were well-suited for use in much of the Baltic Sea by Denmark-Norway, Sweden, Russia, and some of the Central European powers with ports on the southern coast. There were two types of naval battlegrounds in the Baltic. One was the open sea, suitable for large sailing fleets; the other was the coastal areas and especially the chain of small islands and archipelagos that ran almost uninterrupted from Stockholm to the Gulf of Finland. In these areas, conditions were often too calm, cramped, and shallow for sailing ships, but they were excellent for galleys and other oared vessels. Galleys of the Mediterranean type were first introduced in the Baltic Sea around the mid-16th century as competition between the Scandinavian states of Denmark and Sweden intensified. The Swedish galley fleet was the largest outside the Mediterranean, and served as an auxiliary branch of the army. Very little is known about the design of Baltic Sea galleys, except that they were overall smaller than in the Mediterranean and they were rowed by army soldiers rather than convicts or slaves.
Sweden and Russia became the two main competitors for Baltic dominance in the 18th century, and built the largest galley fleets in the world at the time. They were used for amphibious operations in Russo-Swedish wars of 1741–43 and 1788–90. The last galleys ever constructed were built in 1796 by Russia, and remained in service well into the 19th century, but saw little action. The last time galleys were deployed in action was when the Russian navy was attacked in Åbo (Turku) in 1854 as part of the Crimean War. In the second half of the 18th century, the role of Baltic galleys in coastal fleets was replaced first with hybrid "archipelago frigates" (such as the turuma or pojama) and xebecs, and after the 1790s with various types of gunboats.
On the funerary monument of the Egyptian king Sahure (2487–2475 BC) in Abusir, there are relief images of vessels with a marked sheer (the upward curvature at each end of the hull) and seven pairs of oars along its side, a number that was likely to have been symbolical rather than a realistic depiction, and steering oars in the stern. These vessels have only one mast and vertical stems and , with the front decorated with an Eye of Horus, the first example of such a decoration. The eye was later used by other Mediterranean cultures to decorate seagoing craft in the belief that it helped to guide the ship safely to its destination. The early Egyptian vessels apparently lacked a keel. To provide a stiffening along its length, they had large cables, trusses, connecting stem and stern resting on massive crutches on deck. They were held in tension to avoid hogging while at sea (bending the ship's construction upward in the middle). In the 15th century BC, Egyptian galley-like craft were still depicted with the distinctive extreme sheer, but had by then developed the distinctive forward-curving stern decorations with ornaments in the shape of . They had possibly developed a primitive type of keel, but still retained the large cables intended to prevent hogging.
The construction of the earliest oared vessels is mostly unknown and highly conjectural. They likely used a mortise construction, but were sewn together rather than pinned together with nails and dowels. Being completely open, they were rowed (or even paddled) from the open deck, and likely had "ram entries", projections from the bow lowered the resistance of moving through water, making them slightly more hydrodynamic. The first true galleys, the triaconters (literally "thirty-oarers") and penteconters ("fifty-oarers") were developed from these early designs and set the standard for the larger designs that would come later. They were rowed on only one level, which made them fairly slow, likely only about . By the 8th century BC the first galleys rowed at two levels had been developed, among the earliest being the two-level penteconters which were considerably shorter than the one-level equivalents, and therefore more maneuverable. They were an estimated 25 m in length and displaced 15 tonnes with 25 pairs of oars. These could have reached an estimated top speed of up to , making them the first genuine warships when fitted with bow rams. They were equipped with a single square sail on mast set roughly halfway along the length of the hull.
The first dedicated war galleys fitted with rams were built with a mortise and tenon technique, a so-called shell-first method. In this, the planking of the hull was strong enough to hold the ship together structurally, and was also watertight without the need for caulking. Hulls had sharp bottoms without in order to support the structure and were reinforced by transverse framing secured with dowels with nails driven through them. To prevent the hull from hogging there was a hypozoma (υπόζωμα = underbelt), a thick, doubled rope that connected bow with stern. It was kept taut to add strength to the construction along its length, but its exact design or the method of tightening is not known. The ram, the primary weapon of ancient galleys from around the 8th to the 4th century, was not attached directly on the hull but to a structure extending from it. This way the ram could twist off if got stuck after ramming rather than breaking the integrity of the hull. The ram fitting consisted of a massive, projecting timber and the ram itself was a thick bronze casting with horizontal blades that could weigh from 400 kg up to 2 tonnes.
With the consolidation of Roman imperial power, the size of both fleets and galleys decreased considerably. The huge polyremes disappeared and the fleet were equipped primarily with triremes and liburnians, compact biremes with 25 pairs of oars that were well suited for patrol duty and chasing down raiders and pirates. In the northern provinces oared patrol boats were employed to keep local tribes in check along the shores of rivers like the Rhine and the Danube. As the need for large warships disappeared, the design of the trireme, the pinnacle of ancient war ship design, fell into obscurity and was eventually forgotten. The last known reference to triremes in battle is dated to 324 at the Battle of the Hellespont. In the late 5th century the Byzantine historian Zosimus declared the knowledge of how to build them to have been long since forgotten.
The accepted view is that the main developments which differentiated the early dromons from the liburnians, and that henceforth characterized Mediterranean galleys, were the adoption of a full deck, the abandonment of ramming on the bow in favor of an above-water spur, and the gradual introduction of lateen sails. The exact reasons for the abandonment of the ram are unclear. Depictions of upward-pointing beaks in the 4th-century Vatican Vergil manuscript may well illustrate that the ram had already been replaced by a spur in late Roman galleys. One possibility is that the change occurred because of the gradual evolution of the ancient shell-first construction method, against which rams had been designed, into the skeleton-first method, which produced a stronger and more flexible hull, less susceptible to ram attacks. At least by the early 7th century, the ram's original function had been forgotten.
The dromons that Procopius described were single-banked ships of probably 25 oars per side. Unlike ancient vessels, which used an outrigger, these extended directly from the hull. In the later bireme dromons of the 9th and 10th centuries, the two oar banks were divided by the deck, with the first oar bank was situated below, whilst the second oar bank was situated above deck; these rowers were expected to fight alongside the marines in boarding operations. The overall length of these ships was probably about 32 meters. The stern ( prymnē) had a tent that covered the captain's berth; the prow featured an elevated forecastle that acted as a fighting platform and could house one or more siphons for the discharge of Greek fire; and on the largest dromons, there were wooden castles on either side between the masts, providing archers with elevated firing platforms. The bow spur was intended to ride over an enemy ship's oars, breaking them and rendering it helpless against missile fire and boarding actions.
The traditional two side rudders were complemented with a stern rudder sometime after c. 1400 and eventually the side rudders disappeared altogether. It was also during the 15th century that large artillery pieces were first mounted on galleys. Burgundian records from the mid-15th century describe galleys with some form of guns, but do not specify the size. The first conclusive evidence of a large cannon mounted on a galley comes from a woodcut of a Venetian galley in 1486. The first guns were fixed directly on timbers in the bow and aimed directly forward, a placement that would remain largely unchanged until the galley disappeared from active service in the 19th century.
A single mainmast was standard on most war galleys until c. 1600. A second, shorter mast could be raised temporarily in the bows, but became permanent by the early 17th century. It was stepped slightly to the side to allow for the recoil of the heavy guns; the other was placed roughly in the center of the ship. A third smaller mast further astern, akin to a mizzen mast, was also introduced on large galleys, possibly in the early 17th century, but was standard at least by the early 18th century. Galleys had little room for provisions and depended on frequent resupplying and were often beached at night to rest the crew and cook meals. Where cooking areas were actually present, they consisted of a clay-lined box with a hearth or similar cooking equipment fitted on the vessel in place of a rowing bench, usually on the port (left) side.
The faster a vessel travels, the more energy it uses. Reaching high speeds requires energy which a human-powered vessel is incapable of producing. Oar systems generate very low amounts of energy for propulsion (only about 70 W per rower) and the upper limit for rowing in a fixed position is around . Ancient war galleys of the kind used in Classical Greece are by modern historians considered to be the most energy-efficient and fastest of galley designs throughout history. A full-scale replica of a 5th-century BC trireme, the Olympias was built 1985–87 and was put through a series of trials to test its performance. They proved that a cruising speed of about could be maintained for an entire day of travel. Sprinting speeds of up to were possible, but only for a few minutes and would tire the crew quickly. Ancient galleys were lightly built and the original triremes are presumed never to have been surpassed in speed. Medieval galleys are believed to have been considerably slower, especially since they were not designed for ramming. A cruising speed of no more than has been estimated. A sprint speed of up to was possible for 20–30 minutes, but risked exhausting the rowers completely.
Rowing in headwinds or even moderately rough weather was difficult as well as exhausting. In high seas, ancient galleys would set sail to run before the wind. They were highly susceptible to high waves, and could become unmanageable if the projecting rowing frame ( apostis) became overwhelmed by the waves. Ancient and medieval galleys are assumed to have sailed only with the wind more or less from behind for a top speed of about in fair conditions.
It was only in the early 16th century that became commonplace. Both galley fleets and the size of individual vessels increased in size during the early modern period, which required more rowers. The number of benches could not be increased without lengthening hulls beyond their structural limits, and more than three oars per bench was not practicable. The demand for more rowers also meant that the relatively limited number of skilled oarsmen could not keep up with the demand of the larger fleets. It became increasingly common to man galleys with convicts or slaves, which required a simpler method of rowing. The older method of employing professional rowers using the alla sensile method (one oar per rower, with two to three rower sharing the same bench) was gradually phased out in favor of a scaloccio, which required less skill. A single large oar was used for each bench, with several rowers working the oar together. The number of oarsmen per oar rose from three up to five and in some of the largest command galleys, there could be as many as seven to an oar.
All major Mediterranean powers sentenced criminals to galley service, but initially only in time of war. Christian naval powers such as Spain frequently employed Muslim captives and prisoners of war. The Ottoman navy and its North African Barbary corsairs allies put Christian prisoners to the oars in large numbers, but also mixed with volunteers. Habsburg Spain relied mostly on servile rowers, in great part because its organizational structure was geared toward employing slaves and convicts. Venice was one of few major Mediterranean powers that used almost only free rowers, a result of their reliance on alla sensile rowing which required skilled professional rowers. The Knights of Saint John used slaves extensively, as did the Papal States, Florence, and Genoa. The North African ghazi corsairs relied almost entirely on Christian slaves as rowers.
Around the 8th century BC, ramming began to be employed as war galleys were equipped with heavy bronze rams. Records of the Persian Wars in the early 5th century BC by the Ancient historian Herodotus (–25 BC) show that by this time ramming tactics had evolved among the Greeks. Ramming itself was done by smashing into the rear or side of an enemy ship, punching a hole in the planking. This would not actually sink an ancient galley unless it was heavily laden with cargo and stores. With a normal load, it was buoyant enough to float even with a breached hull. Breaking the enemy's oars was another way of rendering ships immobile, rendering them easier targets. If ramming was not possible or successful, the on-board complement of soldiers would attempt to board and capture the enemy vessel by securing it with grappling irons, accompanied by missile fire with arrows or javelins. Trying to set the enemy ship on fire by hurling incendiary missiles or by pouring the content of fire pots attached to long handles is thought to have been used, especially since smoke below decks would easily disable rowers.
Ramming tactics were gradually superseded in the last centuries BC by the Macedonians and Romans, both primarily land-based powers. Hand-to-hand fighting with large complements of heavy infantry supported by ship-borne catapults dominated the fighting style during the Roman era. Thought this decreased mobility of vessels, it meant that less skill was required from individual oarsmen. Fleets thereby became less dependent on highly skilled rowers with a lifetime of experience at the oar.
The Byzantine navy, the largest Mediterranean war fleet throughout most of the Early Middle Ages, employed crescent formations in order to turn the enemy's flanks, as did the Arab fleets that fought them from the 7th century onward. The initial stages in naval battles was an exchanges of missiles, ranging from combustible projectiles to arrows, , and javelins. The aim was not to sink ships, but to deplete the ranks of enemy crews before boarding, which decided the outcome. Byzantine dromons had pavesades (racks of large shields along the railings) which provided protection to the deck crew. Larger ships also had wooden castles between the masts on either side of the upper decks, which allowed archers to shoot from an elevated firing position.
Later medieval navies continued to use similar tactics, with a line abreast formation as standard, as galleys were intended to be fought from the bow. They were at their weakest along the sides, especially in the middle. The crescent formation employed by the Byzantines continued to be used throughout the Middle Ages. The ships on the edges of the crescent would attempt to crash their bows straight into the sides of the enemy ships at the edge of the formation.
The earliest guns were of large calibers, initially of wrought iron, which made them weak compared to the cast bronze guns that would become standard in the 16th century. Early on, guns would be fixed directly to the bow timbers, aimed directly forward in the direction of travel. This placement would remain essentially the same until the galley disappeared from active service in the early 19th century. The introduction of heavy guns and handheld firearms did not change tactics considerably. If anything, it made the bow even more important in offense, both as a staging area for boarders and the obvious place for concentrating firepower. The galley itself could easily outperform most sailing vessels before the establishment of the full-rigged ship. It retained a distinct tactical advantage even after the initial introduction of naval artillery because of the ease with which it could be maneuvered to bare its guns upon an opposing vessel.
British naval historian Nicholas Rodger has described the galley as a "supreme symbol of royal power ... derived from its intimate association with armies, and consequently with princes". This association was elevated even further by the French "Sun King", Louis XIV, in the form of a dedicated galley corps. Louis and the French state he ruled created a tool and symbol of royal authority that did little fighting, but was a potent extension of absolutist ambitions. Galleys were built to scale for the royal flotilla on the Grand Canal at the Gardens of Versailles, purely for the amusement of the court. French royal galleys patrolled the Mediterranean, forcing ships of other states to salute the King's banner, convoyed ambassadors and cardinals, and participated obediently in naval parades and royal pageantry. Historian Paul Bamford has described galleys as vessels that "must have appealed to military men and to aristocratic officers ... accustomed to being obeyed and served".
Sentencing criminals, political dissenters and religious deviants to the galleys also turned the French galley corps into a brutal, cost-effective and feared prison system. Huguenots were particularly ill-treated in this system. They were only a small minority of the prisoners, but their experiences came to dominate the legacy of the galley corps. In 1909, French author (1859–1927) wrote that "after the Bastille, the galleys were the greatest horror of the old regime". Long after convicts stopped serving in the galleys, even after the reign of Napoleon, the term galérien ("galley rower") remained a general term for forced labor and convicts serving harsh sentences.

Privateers specialized in countering piracy, the guarda costa, used periaguas to chase sailing ships against the wind or to conduct Night combat on them.

Sweden was late in the game when it came to building an effective oared fighting fleet ( skärgårdsflottan, the archipelago fleet, officially arméns flotta, the fleet of the army), while the Russian galley forces under Tsar Peter I developed into a supporting arm for the sailing navy and a well-functioning auxiliary of the army which infiltrated and conducted numerous raids on the eastern Swedish coast in the 1710s.

Rowing
Rowers in ancient war galleys sat below the upper deck with little view of their surroundings. The rowing was therefore managed by supervisors, and coordinated with pipes or rhythmic chanting. Galleys were highly maneuverable, able to turn on their axis or even to row backward, though such maneuvers required a skilled and experienced crew. In galleys with an arrangement of three men per oar, as in the larger polyremes, all would be seated, but the rower furthest inboard would perform a stand-and-sit stroke, getting up on his feet to push the oar forward, and then sitting down again to pull it back.

Galley slaves
Slaves were put at the oars only in times of crisis. In some cases, these people would be given freedom after the crisis was averted. Roman merchant vessels (usually sailing vessels) were manned by slaves, sometimes even with slaves as ship's master, but this was seldom the case in merchant galleys.
