The Silesian Piasts were the elder of four lines of the Polish Piast dynasty beginning with Władysław II the Exile (1105–1159), eldest son of Duke Bolesław III of Poland. By Bolesław's testament, Władysław was granted Silesia as his hereditary province and also the Lesser Polish Seniorate Province at Kraków according to the principle of agnatic seniority.
Władysław soon entered into fierce conflicts with his brothers and the Polish nobility. When in 1146 he attempted to take control of the whole of Poland, he was excommunication by Archbishop Jakub ze Żnina of Gniezno and his brothers finally drove him into exile. He was received by King Conrad III of Germany, his brother-in-law by Władysław's consort Agnes of Babenberg, at the Kaiserpfalz of Altenburg. Silesia and the Seniorate Province came under the control of second-born Bolesław IV the Curly, Duke of Masovia. In the same year King Conrad III attempted to regain power for Władysław, but failed. Not until 1157 Duke Bolesław IV the Curly was defeated in a campaign by Konrads successor Emperor Frederick Barbarossa, however, the "Silesian issue" was not mentioned in the treaty concluded by the rulers, and so Władysław remained in exile. He died in 1159 without returning to Poland. In 1163, Bolesław the Curly was pressed by Frederick Barbarossa to return the hereditary Silesian province to Władysław's sons Bolesław the Tall, Konrad Spindleshanks and Mieszko Tanglefoot, though he retained the Seniorate Province and the Polish throne at Kraków. The Duchy of Silesia remained within the Polish seniorate constitution, but Władysław's sons were obliged to pay a yearly tribute to the Holy Roman Emperor.Weczerka, p. XXXIVPetry, p. 86 High Duke Bolesław the Curly also retained control of the most important Silesian cities such as Wrocław, Opole, Głogów, Racibórz and Legnica until 1166 when the Silesian dukes took control of these parts. Władysław's sons probably ruled Silesia together until 1172, when they divided their territory: Bolesław the Tall, eldest brother, received the large area from Legnica up the Oder River to Wrocław and created the Duchy of Opole for his eldest son Jarosław. Mieszko Tanglefoot the smaller Duchy of Racibórz around Racibórz and Cieszyn. Their minor brother Konrad Spindleshanks received Żagań, Głogów and Krosno from the hands of Bolesław the Tall. As Konrad prepared himself for a clerical career at the Fulda monastery, his brother Bolesław administered his possessions until Konrad's early death, when he incorporated Konrad's part into his own duchy. Mieszko at the same time was able to expand his duchy with the former Lesser Poland territories of Bytom and Oświęcim, given to him by High Duke Casimir II the Just, and also with the Duchy of Opole, which he received after the death of Duke Jarosław and his father Bolesław in 1201. One year later, Bolesław's heir, Duke Henry I the Bearded, and his uncle Mieszko moreover specified to rule out the right of succession among their branches, an arrangement which was largely responsible for the special position of what would become Upper Silesia.Pagenstecher, p. 405 In the same year, Poland abolished the seniorate and the Silesian duchies became independent entities.
The royal crown, almost forgotten since the fall of Bolesław II, was destined by him for his eldest son, whom he associated with his rule towards the end of his life. This Henry II the Pious, who succeeded his father in 1238, was, in fact, entirely worthy of the heritage of the first Piasts. Pursuing the very able policy of Henry the Bearded, his son was moreover able to obtain the support of the clergy, with whom his father had had frequent disagreements. In a close alliance with his brother-in-law, Bohemian king Wenceslaus, he consolidated his position in Greater Poland against Barnim I of Pomerania and repelled an attack on castle Lubusz by the margrave of Brandenburg and the archbishop of Magdeburg.Appelt, p. 393 Following an old tradition of his dynasty, he placed himself under the protection of the Holy See, with which he also allied himself against Frederick II. In spite of all his German nobility connections, Henry the Pious would, therefore, assuredly have maintained the independence and prestige of the monarchy if all his plan had not been annihilated by an unforeseen catastrophe. In 1241, he died as a Christians hero in the Battle of Legnica, in which he was attempting to arrest the Mongols invasion. His death left the Silesian Piast dynasty deeply shaken.
These divisions often were the result of fierce and militant conflicts, in which not only the Silesian parties but also their partisans from other parts of Poland and neighboring Bohemia were involved. Whereas the connections to Poland diminished the political ties with Bohemia became increasingly stronger.
In their exile in Germany, the Piasts had witnessed the Ostsiedlung along the Elbe river and strived to develop sparsely populated Silesia by calling in Germans from the west, slowly increasing Silesia's German population which came to dominate the region over the next centuries.
The reign of duke Henry IV Probus was exemplary for the position of Silesias duchies in the area of tension between Poland and Bohemia. After the death of his father Henry III, he was raised in Prague at the court of Bohemian king Ottokar II, who also became his guardian. After Ottokar's death, he did not, as expected, became viceregent of Bohemia for underage Wenceslaus II but was compensated with Kłodzko by Rudolf of Habsburg, who also ennobled Henry to a Reichsgraf of the Holy Roman Empire and granted him his duchy as a Fiefdom.Appelt, p. 394Petry, p. 122 Henry not only obtained the preeminence in Silesia but, with the help of the German party in Polonia Minor,Weczerka, p. XLIVPetry, p. 131 also the duchy of Kraków and became duke of Poland. He initially wanted Wenceslaus to become his successor, but changed his plan on the deathbed and granted Wrocław to Henry III and Kraków to Przemysł II, whereas Kłodzko returned to Bohemia.
After the death of Wenceslaus III, king of Bohemia and Poland, the right to the Polish crown was disputed, being claimed by various Piast dukes as well as the successors of Wenceslaus III on the Bohemian throne. In 1327, John of Bohemia invaded Poland in order to gain the Polish crown. After the intervention of King Charles I of Hungary he left Polonia Minor, but on his way back he enforced his supremacy over the Piasts. In February 1327, five principalities were carved out of Polish Upper Silesia and placed under Bohemian suzerenity: Duchy of Niemodlin, Duchy of Cieszyn, Duchy of Racibórz, Duchy of Koźle and Bytom and the Duchy of Oświęcim and Zator. In April the dukes of Opole and Wrocław also became the tributaries of king John.
In 1329, Władysław I the Elbow-high started a war with the Teutonic Order. The Order was supported by John of Bohemia who managed to enforce his supremacy over the dukes of Masovia and Lower Silesia. In April–May 1329, following Lower Silesian duchies became subjects of the Bohemian crown: Ścinawa, Oleśnica, Żagań, Legnica-Brzeg and Jawor. In 1331 the Duchy of Głogów separated from Poland as well."The new Cambridge medieval history", p. 747
The last independent Silesian Piast – Bolko II of Świdnica – died in 1368. His wife Agnes ruled the Świdnica duchy until her death in 1392. From that time on, all remaining Silesian Piasts were vassals of the Bohemian crown, although they maintained their sovereign rights. In 1335, John of Bohemia renounced his claim to the title of king of Poland in favour of Casimir the Great, who in return renounced his claims to Silesia. Encyclopædia Britannica: Silesia This was formalized in the treaties of Trenčín and Visegrád, ratified in 1339.
The division into small and smallest territories led to a decline of prestige and power. Many Silesian Piasts now merely had the status of with greater rights. Some Piasts entered foreign services as mercenary leaders, like John II of Glogau and Sagan. Henry IX traveled through Europe as a goliard. The descent of the dynasty was also illustrated by the marriages of the dukes. The Silesian Piasts of the 13th and 14th century married into princely families especially from German families, but also other European royal lines, whereas later Piasts also married non-princely and even bourgeois women.
With the adoption of the Protestantism in Silesia, the Piasts again gained importance. Against the Catholic Habsburg dynasty, which ruled Silesia since 1526, the dukes sought political support by entering matrimonies with Protestant, imperial rulers like the Hohenzollern dynasty.Pagenstecher, p. 404 Their last attempts of independent policies were the candidatures of Frederick II of Liegnitz for the Bohemian crown (1526) and of Henry XI (1573), Frederick IV (1576) and Christian (1668) for the Polish crown.
During the 15th, 16th and 17th centuries, various branches of the Silesian Piasts became extinct. In 1532, the last Duke of Opole, John II the Good, died, leaving most of Upper Silesia under direct Bohemian rule. In 1675, the last legitimate Silesian Piast – George William, Duke of Liegnitz – died. The last male Silesian Piast was baron Ferdinand II Hohenstein, who died in 1706, the last female Piast, Charlotte, died in 1707.
In Davies' opinion, the Germanisation of Silesia did not necessarily mean a desire to move apart from Poland. He suggests that it was more likely a way to satisfy the Silesian Piasts' ambitions inside Poland. The planned introduction of German settlers would strengthen Silesia, and also the Silesian Piast claims to the senioral throne in Kraków. Only when the Silesian Piasts' ambitions to rule in Kraków were thwarted did they decide to set their province on a different course.
According to German scholars, by the 14th century, the Silesian Piasts were viewed as Germans on par with the other dukes of the Holy Roman Empire, at least to a much larger degree than dukes of Bohemia and Moravia.
