La Union (), officially the Province of La Union (; ; ; ; ; ), is a coastal province in the Philippines situated in the Ilocos Region on the island of Luzon. The province's capital, the City of San Fernando, is the most populous city in La Union and serves as the regional center of the Ilocos Region.
Bordered by Ilocos Sur to its north, Benguet to its east, and Pangasinan to its south, with the South China Sea to the west, La Union is located 273 kilometers (170 miles) north of Metro Manila and 57 kilometers (35 miles) northwest of Baguio. The province spans an area of 1,497.70 square kilometers (578.27 square miles). As of the 2020 census, La Union had a population of 822,352, resulting in a density of 550 inhabitants per square kilometer or 1,400 persons per square mile. The province had 538,730 registered voters as of 2022. The province official language is Ilocano language (Ilocano), as declared by the provincial government of La Union.
La Union is renowned for its picturesque coastal towns, popular Surfing, and pristine . The province is rich in natural and cultural attractions, offering activities such as red clay pottery, grape picking, Inabel, and pilgrimage tours to historic churches, alongside beautiful waterfalls and Ecotourism. The population includes both the Ilocano people people from the lowlands and the Cordilleran (Igorot people) people from the highlands, contributing to its diverse cultural heritage.
In the northern section, early settlements were established along the coastal plains of Purao (now Balaoan), Darigayos, and the areas surrounding the Amburayan River. These settlements were primarily inhabited by the Samtoy (Ilocanos).
Historian William Henry Scott documented that Balaoan was historically referred to as being "rich in gold" due to its proximity to the gold mines in the Cordillera region. The town served as an emporium for the exchange of Igorot gold through barter and trade among lowlanders, highlanders, and foreign merchants in Tagudin. Similarly, Baratao (now Bauang) has been identified by historians as a settlement of comparable importance to Purao as emporium of gold mines.In the southern section, the areas of Agoo and Aringuey (now Aringay) were early settlements of the Pangasinenses. Agoo functioned as a trading port with Sual as its only rival. Agoo was frequented by Japanese and Chinese ships, whose merchants engaged in commerce or bartered gold with natives. Aringuey served as a coastal maritime trading hub and the terminus of the Aringay-Tonglo-Balatok gold trail, located along the delta of the Aringay (Ifugao) River. This route facilitated the transport of gold from the Ibaloi people villages of Acupan and Balatok in the southern areas of present-day Benguet to the trading centers of Aringay, with further distribution to the port settlement of Agoo.
These trading activities were part of a larger maritime exchange network that extended across the Indian Ocean and the South China Sea. Products exchanged within this network included porcelain, silk, cotton, beeswax, Gemstone, , and precious , with gold being a significant commodity. Artifacts like porcelain and pottery, uncovered during the renovation of the Catholic church in Agoo and now housed in the Museo de Iloko, testify to this trade activity.
Society during this period was divided into two classes: the babaknang and the cailianes. The baknang or babaknang means "the rich" and agtuturay or agturay refers to "the powers-that be" or "the authorities." Propertied, landed, and educated, they formed the local elite class or were the principalia or insulares who spoke Castilian, On the other hand, the unlearned cailianes had less or no property that spoke Ilocano language, Pangasinan, Kankanai and Ibaloi language. Iloco served as the province's lingua franca.
The Spaniards' search for gold (oro) in Igorot territories fueled their expeditions. Religious orders were also motivated by opportunities for missionary work. By 1620, however, the gold trade had begun to decline in the province including the Aringay-Balatok-Tonglo, Bauang and Bangar gold trails. Captain Garcia de Aldana led expeditions into areas like Aringay, Bauang, and San Juan, while Sargento Mayor y Capitan Alonso Martin Quirante centralized the industry in 1624, deploying a force of 1,748 troops, including Spaniards, Chinese, Japanese, Mexicans, and 500 Ilocanos. Natives and mercenaries were often faced harassments forced to reveal gold sources. Many converted to Christianity to avoid persecution, while others fled to the Cordilleras.
In 1661, Andres Malong of Pangasinan, who declared himself king, led a rebellion against Spanish colonial rule in an attempt to liberate several areas in the northern pueblos of Pangasinan and the Ilocos provinces. As part of his campaign, Malong sought to reclaim Agoo from Spanish control. However, his forces, consisting of Pangasinenses, Sambal people, and , suffered a decisive defeat during the Battle of Agoo. The Spanish, with their superior weaponry and strategic fortifications, successfully repelled the rebellion.
In 1754, Igorot chieftain Lacaaden of Bukiagan (now part of Tubao) negotiated with the Spaniards to avoid punitive expeditions by requesting missionaries for his people. This led to the baptism of Igorot chieftain in Tondo under Governor-General Pedro Manuel de Arandía Santisteban . However, resistance resumed in 1759, prompting Pangasinan Governor Arza to launch a military campaign. On 18 March, Lacaaden led a five-hour battle against Spanish forces armed with rifles and artillery. The Igorots held their ground, forcing the Spaniards to retreat along what is now Naguilian Highway, burning villages along the way. The town of Caba became notable as the birthplace of Diego Silang, leader of the Ilocos Revolt (1762–1765) during the British occupation of Manila. Silang persuaded the gobernadorcillo of Balaoan to encourage Ilocanos and Igorots in the town to join his anti-British struggle, which extended to the revolt in Vigan.
In 1820, Don Agustin de Valencia, the gobernadorcillo of Bangar, and Don Agustin Decdec, an Igorot chieftain from Kayan, together with other Igorot leaders from Bacong and Cagubatan in Tagudin, formalized an Ilocano-Igorot bodong (peace pact). This agreement, facilitated by the Capitanes Pasados, reinstated highland-lowland trade, which had been disrupted three years earlier due to the killing of an Igorot in Tagudin and the subsequent retaliatory killing of an Ilocano from Bangar.
By 1826, the Spanish established the Commandancia del Pais de Ygorrotes y Partido del Norte de Pangasinan to combat tobacco smuggling. Lieutenant Colonel Guillermo Galvey led campaigns into the Cordilleras, using towns like Agoo, Bauang, Bacnotan, and San Juan as military bases.
From 18th to 19th century the coastal towns frequently faced raids by Moro pirates locally known as tirongs (raiders, attackers, pirates) and Chinese pirates, who looted barrios or villages and captured women and children. To counter these attacks, the Spaniards built circular adobe , or baluartes, in 1836. These structures, ranging from 6 to 7 meters in height, were constructed along the coastline in towns such as Namacpacan (Luna), Balaoan, San Fernando, and Bauang. These baluartes played a crucial role in protecting coastal settlements and securing trade routes throughout the 19th century.
Distance posed significant challenges to local administration. From Vigan, the capital of Ilocos Sur, the three southernmost pueblos (Balaoan, Namacpacan, and Bangar) were located approximately 13 to 14 hours away on foot. The cailianes and the babaknang often complained about the physical distance from their officials in the cabecera or capital town. Similarly, from Lingayen, the capital of Pangasinan, the nine northern pueblos (Santo Tomas, Agoo, Aringay, Cava, Bauang, Naguilian, San Fernando, San Juan, and Bacnotan) were also burdened by the 13 ½ hours of travel required from Bacnotan.
The situation was even worse for the 40 to 45 rancherías located in the depths of the Eastern País del Igorotes. The commandancia established in 1826 proved ineffective in maintaining order among the Igorrotes, whose remoteness from central authorities led to rampant smuggling of tobacco and other merchandise, thereby disrupting the region's economic stability. on 29 October 1849, Governor General Claveria signed the promovido (proposal) to unite the Pangasinan-Ilocos Sur-Cordillera areas into a new province called La Union (the official name designated by Claveria himself) as San Fernando as cabecera (capital) and Amburayan River in the north and Rabon River in the south as provincial boundaries. For 124 days, high and important Spanish colonial officers studied and deliberated on the proposition to create La Union or not.
On 2 March 1850, Governor General Antonio María Blanco signed the s uperior decreto that founded La Union – the 34th province since the founding of Cebu in 1565. It was classified as a Gobierno Politico-Militar (Political-Military Government). Blanco appointed, on 4 March 1850, Captain Toribio Ruiz de la Escalera (Claveria's former trusted aide de camp) as the first Gobernador Military y Politico. La Union is the union of lands, people, cultures and resources. On 18 April 1854, Queen Isabella II of Spain issued the real orden (royal decree) from Madrid confirming Blanco's s uperior decreto.
By 1869 and 1885 Rosario and Tubao became towns in La Union respectively. In 1869, Governor-General de la Torre converted Concepcion into Rosario, which remained spiritually dependent on Santo Tomas. Despite the bishop's refusal to assign an assistant priest, Rosario became the 13th town, with its priest overseeing both towns. In 1885, after 12 years of petitions, Tubao was officially recognized as the 14th town as San Isidro de Tubao, named after the patron saint of farmers.
By 1860, there was significant progress in commerce and agriculture in the province. La Union became an exporter of tobacco, rice, and Biancaea sappan from the 1860s to the 1880s. Tobacco was the primary product and the reason for the province's economic growth. Spanish authorities relied heavily on the prized leaf for further economic development. The industry was so lucrative that a Tobacco Monopoly was established. All tobacco leaves were strictly monitored and purchased exclusively by the government at a fixed price.
Simultaneously, other provinces were also experiencing economic growth. Relying on its own indigenous resources, La Union did not import rice, palay, tobacco, sibucao, or other products during this period.
By 1887, the province's population had grown to 100,775. La Union's heterogeneous population mingled throughout this period. The Chinos, or Mestizos de Sangley, Peninsulares, and Insulares coexisted with the native Pangasinenses, Ilocano people, and Igorot people (particuallaly the Kankanaey people and Ibaloi people), whether Christianized or non-Christianized. The Christianized Igorots or Nuevo Cristianos were often referred to as Vagos or Bago.

In Balaoan, a secret revolutionary group formed by seven prominent citizens namely; Luciano Resurreccion, Proceso Ostrea, Antonio Ostrea, Rufino Zambrano, Fernando Ostrea, Patricio Lopez, and Julian Peralta—sought to revolt against the tyranny of the Guardia Civil and Parish. The group was betrayed by Captain Juan of Agoo to the friars. They were arrested, and without trial, executed by firing squad at the town cemetery. Only one of the men survived, having been wounded in the leg. In their honor, a Masonic lodge named Siete Martires was established.
In Agoo, around 60 suspected subversives were executed by the Guardia Civil and their bodies later interred in a corner of the town plaza. In nearby Aringay, 96 citizens were shot without trial by Spanish forces. A monument was later erected in the plaza to honor these patriots. On 10 September 1896, Spanish authorities, led by Friar Rafael Redondo, arrested Dr. Lucino Almeida, the highest-ranking native official in La Union, along with other suspected revolutionaries. They were accused of involvement in a fabricated conspiracy to assassinate Spanish officials, based on a false confession from a telegrapher. Almeida and 20 other prominent natives were exiled to Balabac Island.
Despite these events, La Union was hailed as "una provincia modelo" (a model province) in 1897 by the pro-government El Comercio for its contributions to Spain's defense. However, in 1898, the relative tranquility of La Union was shattered when an uprising and massacre in Santo Tomas ignited widespread agitation.
Uprising of 1898
The revolution in La Union began on 22 May 1898, with a small uprising in Santo Tomas. A shot from a small revolver ( “una revolver pequeña”) was heard, igniting the “seditious movement of Union.” A single shot from this revolver ended the life of the much-hated Augustinian friar, Mariano Garcia, marking the end of Spanish rule in the province. The enraged revolutionaries stormed the convent, seized the priest, chained him, and beheaded him, his head rolled to the ground like a soccer ball. This act sparked a series of mass massacres (“”) throughout the province.
The subsequent violence led to the massacre of various individuals, including Garcia's visitors and others. Women also became victims of brutal acts, with one storekeeper in San Fernando left mentally deranged. In San Juan, pro-Spanish inhabitants were massacred, while in Caba, pro-Spanish sympathizers were captured and held incommunicado in the mountains. In Bauang, revolutionaries clashed with Spanish soldiers and seized the town hall, led by Captain Remigio Patacsil. ', the leader who led the Philippine revolution in La Union]]From May to August 1898, citizens of La Union fought several heroic battles against the Spanish forces in key towns such as Darigayos (Luna), Bacnotan, Rabon (Rosario), San Fernando, Bangar, and Balaoan. Despite heavy losses and diminishing supplies, Spanish forces under Lieutenant Colonel Jose Herreros mounted a five-day defense in Casa Real''. However, they were eventually overwhelmed by revolutionaries in towns like Bangar, Bacnotan, and Balaoan, and the Spaniards were forced to surrender. The final stand in Balaoan saw Spanish forces barricaded in the convent, but despite their valiant defense, they were outmaneuvered, and many escaped to Ilocos Sur.
On 22 July, Nueva Ecija troops, reinforced to over 600 men, arrived in San Fernando after Dagupan surrendered to General Francisco Makabulos. The town was under siege by revolutionaries led by General Mauro Ortiz. Spanish forces, commanded by Lieutenant Colonel Jose Garcia Herrero, fortified themselves in key buildings, awaiting reinforcements. The ensuing battle lasted for 120 hours, with the Spanish troops enduring extreme conditions. Major Ceballos, who had surrendered in Dagupan, attempted to negotiate the surrender of Spanish forces in San Fernando, ultimately convincing Herreros to capitulate. The proud Spaniards with the Cuerpos de Voluntaries (Corps of Volunteers) did not simply put up the white flag. This led to the signing of the Actas de Capitulaciones (Acts of Surrender), and San Fernando became the 13th of 29 towns to witness Spanish surrender, with 400 soldiers and eight officers capitulating.
After securing San Fernando, the Tinio Brigade and other revolutionaries continued north from 31 July – 18 August 1898. Key battlegrounds included the rice fields of San Juan, Bacnotan, Namacpacan, Balaoan, and Bangar. Many local Katipuneros joined the Tinio Brigade after this ordeal, which saw stubborn resistance from entrenched Spanish troops in the convent.
Final Victory c.1890s]] In the Amburayan River, Spanish forces built defensive trenches and placed bamboo traps. However, the Revolutionary, buoyed by previous victories, attacked with renewed vigor. In San Juan, they burned municipal buildings and the homes of Criollo people, resulting in a massacre of over 100 families attempting to flee. In Agoo, pro-Spanish sympathizers were captured and executed in the mountains.
As Spanish forces retreated, they reinforced their positions in Balaoan and Bangar, but revolutionaries quickly fortified their own defenses. Any potential reinforcements from neighboring provinces were blocked. In Darigayos Cove, Filipino rebels burned all anchored boats, preventing escape by sea. The revolutionaries then moved to Bangar, successfully besieging the Spanish forces, resulting in a decisive victory on 7 August 1898. The surrender of 87 Spaniards marked a significant milestone, with the remaining forces fleeing to Ilocos after just four days of fighting, which saw minimal Filipino casualties.
By 18 August 1898, La Union had achieved final victory, marking the definitive collapse of Spanish resistance in the province. This victory brought the revolutionaries closer to their ultimate goal of freedom from Spanish colonial rule.
On 16 November 1899, Emilio Aguinaldo arrived in La Union via the Tubao trail, making his way to Aringay, where he was welcomed by the townspeople ( cailianes) and elites ( babaknang). From Aringay, Aguinaldo continued his journey through Cava, Bauang, and Naguilian where they spent the night in convent. On 18 November 1899, American forces under General Samuel Baldwin Marks Young entered La Union, landing in Rosario via Rabon Point along the coast in pursuit of Aguinaldo. At dusk, American forces engaged 130 Filipino revolutionaries at Tubao, commanded by Captain Santiago Fontanilla , who led a force of four officers and 87 rifles. The Americans then moved toward Aringay, where Major Matthew Arlington Batson led an attack on the town the following morning. He was wounded in a skirmish with Guerrilla Unit No. 5, an event known as the Battle of Aringay River.
Throughout the week, heavy fighting ensued between American forces and five Filipino guerrilla units in La Union led by Colonel Juan M. Gutierrez:
Simultaneous battles were fought across various towns, including Santo Tomas, Aringay, Naguilian, Bauang, and San Fernando. By 19 November, the Americans had taken Santo Tomas and Agoo. On 20 November, General Young entered San Fernando where describe the town as “series of the most formidable entrenchments,” capturing the revolutionary headquarters and estimating the presence of 1,000 Filipino insurgents. Several revolutionaries were captured. Meanwhile, Aguinaldo continued his escape, traveling through the mountain roads of San Fernando, San Juan, and Bacnotan, narrowly evading capture. Upon reaching Balaoan, he learned of a plot to avenge Antonio Luna, who had been killed five days earlier. This plot, intended to unfold in Luna's mother’s hometown of Namacpacan (now Luna), was thwarted by Doña Laureana Luna y Novicio.
On 21 November, Aguinaldo arrived in Bangar, escorted by General Tinio, before continuing his journey to Ilocos Sur. On the same day, La Union's insurrecto governor, Dr. Don Lucino Almeida y Almendrada, paid a courtesy call to General Young, offering assistance to the U.S. government. By 23 November, Young reaches Namacpacan (now Luna). While seemingly cooperating with U.S. forces, Almeida secretly supported the Filipino guerrillas by establishing a network with town leaders and chieftains. He mobilized resources such as money, rice, and provisions for the guerrillas, and his Hacienda in San Juan, Balaoan, and Bacnotan served as covert guerrilla hideouts.
From January to February 1900, the Tinio Brigade engaged in several battles against American forces in La Union, achieving notable victories despite being outnumbered. In January, they repelled American forces at Malabita, San Fernando and ambushed a 40-man patrol near Bangar.
In February, they conducted additional ambushes at Sabang, Bacnotan, Panicsican, San Juan, and Kagunan in Balaoan. On 26 February, they successfully retaliated against an ambush between San Juan and Bacnotan, killing several American troops, including a captain-doctor, and capturing supplies. By April 1900, Colonel William Penn Duvall, the U.S. military governor of San Fernando, grew suspicious of Almeida's activities. First Lieutenant William Thomas Johnston was assigned to investigate Almeida's involvement in the resistance. After months of scrutiny, Almeida was court-martialed on 3 June 1900, and exiled to Guam in January 1901.
Following Almeida's conviction, local leaders in San Fernando, Bacnotan, San Juan, Tubao, Agoo, and Rosario ceased supporting the guerrillas. Many of Almeida's former supporters switched allegiances to save themselves, earning the nickname chameleons or "balimbings." Johnston's anti-guerrilla efforts, aided by local spies, contributed to the overall pacification campaign. One of them, Crispulo Patajo native from Bauang, served as a spy, scout and leader for the U.S. forces to suppress guerrilla resistance in the province. On 17 April 1900, Patajo's forces attacked and pacified the guerrilla presence in Barrio Castro, Bangar, capturing weapons and forcing insurgents to retreat. From May to June 1900, Crispulo Patajo led successful anti-guerrilla operations throughout La Union. He attacked Fontanilla's band in the Pagalan Mountains on 26 May, killing 10 insurgents and capturing 13 rifles. His forces continued to clear towns like Naguilian, Bauang, and Aringay, killing or capturing guerrillas.
In San Fernando, Patajo pacified the town in one week, capturing officers and securing rifles. He also targeted northern towns like San Juan and Bacnotan, eliminating a guerrilla company and capturing 80 rifles. Despite these successes, Colonels Juan Gutierrez and Joaquin Luna managed to escape and relocated their camp further north.
Between March and April 1901, guerrilla forces led by Aniceto Angeles, Sixto Hipolito, and Santiago Fontanilla engaged in skirmishes with American troops in various areas, including Sitio Guilong (Balaoan), Sitio Kalumboyan (Balaoan), Sitio Nabual (Bacnotan), and Barrio Castro (Bangar) that leads Major Aniceto Angeles withdraws. While they achieved some victories, their effectiveness diminished due to internal divisions, lack of discipline, and the failure to maintain unity.
By 1 May 1901, the Tinio Brigade surrendered to the Americans in Sinait, marking the end of the Philippine-American War in La Union and the surrounding region.
In 1901, La Union transitioned to Civil Government, signaling the start of a more organized and democratic system inspired by American models. The transition marked a shift from the "spiritualism" enforced by the Catholic friars under Spanish rule to a secular system.
Despite this shift, U.S. military leaders, including Colonel Duvall, resisted relinquishing power and frequently clashed with the Philippine Commission, led by Civil Governor William Howard Taft. The conflict escalated to U.S. Secretary of War Elihu Root, who intervened to ensure La Union’s formal adoption of civilian governance on 15 August 1901. Joaquin Ortega became La Union's first civilian governor, ushering in a new era of governance. However, key positions, such as the provincial treasurer, remained under American control. The colonial administration also prioritized education, suffrage, civil rights, and political participation, thus empowering Filipinos to engage in the Democracy.
Introducing the Thomasites—American teachers tasked with promoting "Americanization." English language became the primary medium of instruction, aiming to instill American ideals. A notable example of this initiative’s success is Camilo Osias, a student from Balaoan, who pursued studies in the U.S. and later emerged as a respected Teacher and public servant. Municipal Building ', c. 1940s]]By 1902, La Union's education system had grown to include 89 schools spread across various pueblos'' (towns). A total of 8,917 pupils were enrolled—5,652 boys and 3,265 girls—constituting 15% of the province's population. Schools were established in key towns like San Fernando, Bangar, Rosario, Aringay, Cava, Agoo, Balaoan and Namacpacan (Luna), with some operating in repurposed Spanish-era convents.
In 1902, public health boards were established to address health crises such as cholera outbreaks. Measures taken during the 1902 epidemic proved effective in curbing a severe outbreak in 1908–1909. Governor Sixto Lachica Zandueta championed the establishment of a resident health officer for La Union, leading to the creation of a sub-health district by 1910. Public health continued to improve under Governor General Francis Burton Harrison (1913–1921), with coordinated efforts significantly reducing cholera cases by 1914.
In 1902, Camp Wallace was established on Poro Islet, San Fernando, under Frank Tompkins, as it was considered a strategic location. The U.S. formally acquired it as a military reservation on 1 September 1903, and the War Department set guidelines for its creation on 13 October 1903. Governor Joaquin Ortega supported the establishment of a permanent military post in San Fernando, endorsing a petition signed by 2,637 citizens on 9 August 1902.
The integration of non-Christian tribes from the Cordilleras, referred to as the “taga-Montañosa,” became another priority. In 1902, Governor Taft proposed incorporating these groups into the municipal code or merging them with Benguet. By 1905, tensions between Bangar’s lowlanders and mountain communities led to court interventions. In 1906, Igorot people settlements were transferred to sub-provinces of Benguet and Amburayan under Lepanto-Bontoc to resolve jurisdictional and tax-related disputes. By 1911, many non-Christians sought permission to resettle in lowland areas. By 1912, Christianized Igorot "Bago" communities in Rosario, Tubao, San Fernando, San Juan, and Bacnotan were fully integrated. Boundary adjustments and the conversion of mountain settlements into followed, with Pugo officially becoming a township on 11 December 1911. Despite proposals for a new province, the municipal districts of Sudipen, San Gabriel, Santol, Pugo, Bagulin, and Burgos remained part of La Union. These districts served as models of harmonious Christian-Igorot relations during the colonial period. By 1920, San Gabriel, Pugo, Sudipen, and Santol became official towns under Section 2 of Act No. 2877, or the Revised Administrative Code of the Philippine Islands; Bagulin followed in 1922, and Burgos in 1925, under Executive Order No. 54. Under Governor General William Cameron Forbes (1909–1913), infrastructure development flourished in La Union. Roads, airports, ports and railways (Ferrocarril de Manila-Dagupan) were expanded, with the rail line reaching Aringay in 1910 and Bauang in 1918. This enhanced connectivity significantly boosted the local economy, particularly in southern La Union, by linking it to Dagupan. Major projects included the construction of the Taboc Bridge on the San Juan-Bacnotan Road, the Naguilian Road, the Bacnotan-Balaoan Wagon Road, the San Fernando Wharf, and the Amburayan River irrigation system, which supported tobacco and rice fields, bolstering agriculture and trade. By 1915, under Governor Mauro Ortiz, the Naguilian Road was extended to Baguio, the Poro Point became operational, the Balaoan-Bacnotan Road was initiated, and the Baroro and Darigayos Bridges were completed. By 1921, over 150 kilometers of roads had been developed, facilitating commerce and the transportation of goods.
The transition to the Philippine Commonwealth in 1935 granted La Union greater autonomy and opportunities for political engagement, though colonial structures persisted. This era fostered local development while reinforcing American influence. Full independence remained elusive until the Philippines gained sovereignty in 1946. The American colonial period left a mixed legacy in La Union. While it brought modernization in education, infrastructure, and public health, it also entrenched colonial dependency and caused lasting cultural and social impacts. The memory of resistance and the province's enduring struggle for identity continues to shape its historical narrative and aspirations for self-determination.
As the Filipinos awaited independence under the Tydings-McDuffie Act, World War II erupted, further delaying their aspirations for sovereignty. La Union Profile: Gallery of Governors – Province of La Union :: Official Website
By 11 December, the Japanese forces had successfully captured Vigan and dispatched additional troops to seize Laoag and its airfield. As American forces retreated, Masaharu Homma left a small garrison in Vigan and redirected the main forces to support operations at Lingayen Gulf.
By 20 December, the combined forces of the Col. Kanno and Shizuichi Tanaka Detachments advanced south along Route 3. By 21 December 1941, Japanese forces had occupied Bacnotan following the successful overcoming of Philippine defenses in the area. On 22 December, they advanced to San Fernando further consolidating their position. Japanese troops also landed in Agoo and swiftly established control over the town by early 1942. Despite these rapid advances, Filipino and American forces continued to resist the Japanese occupation, contributing to the broader efforts of the Allied campaign in the Philippines.William L. O'Neill, A Democracy at War: America's Fight at Home and Abroad in World War II, p. 115
Battle of Rosario (Invasion of Lingayen Gulf)
On 22 December 1941, the Japanese 4th Tank Regiment and the 47th Infantry Regiment under the command of Col. Isamu Yanagi, supported by a massive flotilla of navy ships tried to land in Agoo to make it one of three major beachheads for the Japanese Invasion of Lingayen Gulf, although weather dispersed their forces and made them deploy on a wide stretch of beach that ranged from Poro Point (San Fernando) to as far south as Damortis. These forces later met the commonwealth defence forces—consisting of the 26th Cavalry Regiment (Philippine Scouts), the Philippine 21st Division, the Philippine 11th Division, and the newly formed Philippine 71st Division—in what would later be called the Battle of Rosario.
During the Japanese occupation in the province, La Union was governed by Gov. Jorge Camacho (1941–1942), Gov. Bonifacio Tadiar (1942–1944), and Gov. Bernardo Gapuz (1945) under the administration of President José P. Laurel's Japanese-sponsored "puppet" government. The province endured strict military controls, forced labor, food shortages, and widespread violence including extrajudicial killings and sexual violence. Despite these conditions, resistance movements emerged, with many residents engaging in guerrilla warfare against Japanese forces. Guerrilla camps was established all over the province including Camp Spencer in Darigayos, Luna and Camp 121 and Barrio San Cristobal in Bangar.
Mangkaeng Massacre
In Naguilian, over 400 refugees from the barrios of Imelda, Natividad, and Ortiz sought refuge in the small, forested sitio of Mangkaeng in barrio Gusing Norte to escape Japanese forces stationed in the town proper as part of General Tomoyuki Yamashita’s rear guard during his retreat to the Cordillera mountains.

On the early morning of 23 January 1945, Japanese troops launched a sudden and brutal attack on Mangkaeng, aiming to eliminate potential resistance or witnesses. The unarmed villagers were caught off guard as gunfire (bayonet) erupted, killing men, women, and children. Some families attempted to flee into nearby creeks and the dense forest, hoping for cover, but the soldiers were relentless, pursuing and killing those who tried to escape. Others hid in nearby caves or bushes, clinging to the hope of survival while hearing the cries of those captured. Some survivors managed to reach neighboring villages, where they warned others of the massacre, spreading shock and grief across the province.
Battle of Baroro
On 4 January 1945, Filipino-American forces captured the Baroro Bridge in Bacnotan, marking a significant turning point in the liberation of the province during World War II. The bridge, a vital link connecting Northern Luzon to San Fernando, was a strategic objective for the Allied forces. The operation began with an assault by the 121st Infantry Regiment of the United States Armed Forces in the Philippines, Northern Luzon (USAFIP-NL), against Japanese positions along the south bank of the Baroro River. The battle was characterized by heavy exchanges of gunfire, with the Filipino-American troops ultimately securing the bridge after intense fighting. This victory played a crucial role in ensuring the liberation of La Union and was followed by subsequent operations, including the Battle of San Fernando and the capture of Bacsil Ridge.
Battle of San Fernando Following the Battle of Baroro, Allied forces launched a concerted attack on Japanese strongholds to the south of Baroro. This included operations targeting key enemy positions along Oaig Creek, where it crossed the San Fernando–Camasin Road, as well as strategic locations such as Reservoir Hill, Insurrecto Hill, and the Bacsil–Apaleng Range. These assaults took place during the second week of February 1945 as part of the broader campaign to secure San Fernando and its surrounding areas.
By 24 March 1945, after the Battle in Bacsil Ridge Allied forces had successfully secured the entire San Fernando area. This victory enabled the establishment of a critical military base "Camp Wallce" at Poro Peninsula, which became the headquarters for U.S. Army Base M. The area also served as a vital build-up zone for the projected invasion of Japan, marking a crucial step in the Allied preparations for the final stages of the Pacific War.

Volckmann, and the Japanese Imperial forces under by General Tomoyuki Yamashita.
The Battle of Bacsil Ridge ended the month-long battle for control of San Fernando. The Japanese defenders called the Hayashi Detachment, composed of 3,000 armed troops and 2,000 unarmed support forces, took hold of San Fernando and its surrounding areas which denied entry to the port of the town and a road leading to Baguio. As part of the San Fernando-Bacsil Operations, the 1st Battalion of 121st Infantry were sent to loosen the enemy positions starting late February with the assistance of the Allied Air Force.Volckmann, R., 954, We Remained, New York:W.W.Norton & Company, Inc.;
The 1st Battalion made a general attack to the ridge on 16 March 1945 and fought the Japanese defenders until the capture of Bacsil on 19 March. On the same day, the 3rd battalion captured the Reservoir Hill. The Battle of Bacsil Ridge between the Filipino soldiers and recognized guerrillas and the Japanese Forces resulted in the recapture of San Fernando, La Union. Which resulted in the capture of San Fernando, La Union on 23 March 1945, and Bacnotan, La Union and the military offensive throughout the province ended on 24 March after two months of fighting.

Meanwhile, combat units from the "B" company, 1st Battalion, 121st Infantry, USAFIP-NL attacked the defensive lines in Bauang to aid the 1st Battalion, 130th Infantry (US) in its advance from the south. Bauang was first liberated on 19 March 1945, followed by the declaration of the end of operations at La Union on 24 March 1945. On 4 January 1945, La Union was liberated by the Battle of San Fernando and Bacsil Ridge.
As San Fernando was in ruins at the time, Bacnotan became the provisional seat of the province administration after the war. The La Union National High School was also relocated to Bacnotan as a result of this relocation. When things returned to normal, the provincial government was relocated to San Fernando, followed by the La Union National High School. The North Provincial High School was established after the provincial high school in Bacnotan was transferred (now Bacnotan National High School).
The powerful family factions which had dominated La Union politics since before the American colonial era largely remained in place, although the family of Congressman Jose D. Aspiras became much more prominent after he became Marcos’ Tourism Minister. The main political change was the increased power of regional and provincial offices of national agencies, whose directors were answerable directly to Marcos.
This technique used by Marcos to consolidate political power did not get much resistance in the Ilocos Region, including La Union, which had strong ethnic associations with the Marcos family.Cortes, Rosario Mendoza. (1990) Pangasinan, 1901–1986: A Political, Socioeconomic, and Cultural History. New Day Publishers. The Marcos administration's use of violent methods for stifling dissent thus mostly took place in other, non-Ilocano provinces, such as nearby Abra, Kalinga, and Mountain Province. Long-time second district congressman Manuel T. Cases had formed an alliance with Marcos along with the other strongman congressmen of the Ilocos Region, and his successor Jose D. Aspiras was also a close associate of Marcos who was made Minister of Tourism after Martial Law was declared. But there were still La Union natives who were willing to object to the authoritarian practices and abuses of the Marcos administration, despite personal risk.

This included San-Fernando-raised student activists Romulo and Armando Palabay, UP Students and La Union National High School alumni who were imprisoned for their protest activities, tortured at Camp Olivas in Pampanga, and later separately killed before the end of Martial Law. Romulo (age 22) and Armando (age 21) were posthumously honored when their names were etched on the Wall of Remembrance at the Philippines' Bantayog ng mga Bayani, which honors the heroes and martyrs who fought the authoritarian regime.Burgonio, TJ "Museum puts a face on little-known martial law martyrs", Philippine Daily Inquirer, 21 September 2008.
Agoo, La Union, native Antonio L. Mabutas had become Archbishop of Davao by the time of Martial Law, and spoke actively against the human rights abuses of that time, particularly the torture and killings of church workers. The pastoral letter he wrote against Martial law, "Reign of Terror in the Countryside," is notable for having been the first pastoral to be written against Marcos' martial law administration, and even doubly notable because Mabutas was considered a conservative within the Catholic church hierarchy in the Philippines.
Alongside the rising influence of social media outlets Twitter and Instagram, these factors led to a drastic tourism boom that made San Juan—previously been seen as just one of the Philippines' many surfing venues—a major backpacker's destination whose attractions centered on surfing and art. San Juan began to be featured prominently in independent films such as Jay Abello's 2015 film Flotsam and JP Habac's 2017 film I'm Drunk, I Love You, and the province began to be referred to by the colloquial initialism "ElYu."
Among Philippines literary circles, the town of Bauang has also become a pilgrimage site of sorts for celebrating the life of and works of writer and World War II martyr Manuel Arguilla, with writers visiting the author's hometown to experience the landscapes that inspired him, and which featured prominently in his stories.
