Santo Tomás, officially the Municipality of Santo Tomas (; ; ), is a coastal municipality in the province of La Union, Philippines. According to the , it has a population of people.

Etymology

The name Santo Tomás originates from the Spanish term for Saint Thomas (Saint Thomas Aquinas), a 13th-century Catholic priest, philosopher, and theologian celebrated for synthesizing faith and reason, authoring the Summa Theologica, and shaping Western Christian thought.

The town was named in his honor by Augustinian friars in the 16th century during the Spanish colonization, following the tradition of dedicating settlements to Christian saints. The town's rich religious heritage continues to be a significant part of its identity, with numerous churches and cultural practices rooted in its Catholic origins.

History

Early history During its early history, the town served as a settlement for the Pangasinans, strategically located along its fertile coastal plains. Together with neighboring areas such as Agoo and Aringay, it played a pivotal role in the trade network of Northern Luzon. Its naturally shaped coastline offered an excellent harbor for foreign vessels entering Lingayen Gulf, establishing the area as a significant trading hub. This strategic location attracted Japanese and Chinese merchants who engaged in the exchange of goods with the native population, transforming the settlement into a thriving center of commerce.

One of the most highly valued trade items was gold from the Cordilleras (modern-day Benguet), which was greatly prized by foreign traders. In addition to gold, the region also exported beeswax—used in the production of candles and various other goods—along with porcelain, silk, cotton, gemstones, rice and beads. These goods were traded for luxury items, tools, and other valuable commodities brought by foreign merchants.

Spanish Colonization In June 1572, Spanish voyagers led by conquistador Juan de Salcedo landed in the trading port of Agoo after navigating the Angalacan River in Pangasinan and following three Japanese ships. Upon their arrival, a brief skirmish broke out between the Japanese merchants and the local natives. Salcedo demanded tribute from them to the Spanish Crown and subsequently subjugated the population to Christianity.

By 1578, the Franciscans established a permanent settlement in the area, constructing a visita (a small mission chapel) made of bamboo. They introduced the catechism to the locals and integrated the visita into the larger ecclesiastical district centered in Agoo. Santo Tomas, along with the present-day towns of Tubao, Rosario, Pugo, and Aringay, was initially part of Agoo's territory.

In 1661, Andres Malong of Pangasinan led a rebellion against Spanish colonial rule in an attempt to liberate several areas in Northern Luzon, including the present-day province of La Union. As part of his campaign, Malong sought to reclaim Santo Tomas from Spanish control. However, his forces suffered a decisive defeat during the Battle of Agoo, where the Spanish, with their superior weaponry and strategic fortifications, repelled the rebellion.

The Spanish authorities had already established the settlements in Santo Tomas as a barrio of Mangaldan, a pueblo under the province of Pangasinan, headed by a gobernadorcillo and a cabeza de barangay. Elites, or the principalía and insulares, became the prominent people holding positions of power.

By the 1700s, due to population pressures and oppressive conditions under Spanish rule, Ilocano migrants from the Ilocos provinces and nearby towns began settling in the coastal areas of La Union. Initially arriving in Agoo, they gradually moved south to the fertile plains of Santo Tomas. They settled, cultivated lands for agriculture, and improved the settlement, with intermarriage occurring between the Ilocano settlers and the Pangasinans leading locals to Ilocanized Pangasineses.

In 1764, Santo Tomas was officially separated from Mangaldan and became a pueblo (town) under a Spanish Royal Decree. Don Lorenzo de los Reyes, a prominent native of Santo Tomas, was appointed its first gobernadorcillo, overseeing local governance under the Spanish administration. However, the Spanish authorities were displeased with his administration, and as a result, the town was merged back with Agoo.

By 1785, Santo Tomas regained its autonomy as a town after nearly 21 years as a barrio of Agoo. Santo Tomas’ cabeza de barangay, Don Domingo Carpio, courageously initiated the secession movement of Santo Tomas from Agoo. His sincerity and dedication as a leader earned him the overwhelming support of his townmates. The strong backing from the people forced the Spanish authorities to surrender control of the town. Under the administration of Don Domingo Carpio, the town experienced remarkable growth and stability. His excellent leadership led to his appointment as Gobernadorcillo.

On October 29, 1849, Governor-General Narciso Clavería y Zaldúa issued a decree merging eight towns from Pangasinan, including Santo Tomas, three from Ilocos Sur, and 40-45 rancherías in the Cordillera to form the province of La Union. The establishment of the province was formalized on March 2, 1850, through the Superior Decreto signed by Governor-General Antonio María Blanco. Santo Tomas was one of the founding towns, alongside San Fernando (cabecera), Agoo, Aringay, Cava (Caba), Naguilian, Bauang, San Juan, Balaoan, Namacpacan (Luna), Bangar, and Bacnotan. This formation was confirmed on April 18, 1854, by a royal decree (real orden) from Queen Isabella II of Spain.

The province experienced economic progress, particularly in agriculture, with tobacco and rice as Santo Tomas’ main products.

On August 7, 1869, Governor-General Carlos de la Torre decreed the conversion of Barrio Concepcion in Santo Tomas into a new town called Rosario. Rosario was established as a civil town but remained spiritually dependent on Santo Tomas. However, the Catholic Bishop refused to assign a co-adjutor priest due to insufficient stipends, leaving Rosario reliant on the priest of Santo Tomas, who managed both parishes.

Philippine Revolution The Philippine Revolution in La Union began on May 22, 1898, with a small uprising in Santo Tomas. A single shot from a small revolver killed the much-hated Augustinian friar, Mariano Garcia, marking the end of Spanish rule in the province. Enraged revolutionaries stormed the convent, seized the priest, chained him, and beheaded him. This act sparked a series of massacres (hecatombes) throughout the province.

Through the years, the residents of Santo Tomas actively participated in the fight for independence against Spanish colonial rule across La Union. Under the leadership of General Manuel Tinio, a close ally of the Philippine president Emilio Aguinaldo, the locals engaged in significant resistance efforts in Northern Luzon.

By August 18, 1898, La Union had achieved final victory, marking the definitive collapse of Spanish resistance in the region. This victory brought the revolutionaries closer to their ultimate goal of freedom from Spanish colonial rule.

American Colonization

The independence of the Philippines from Spain was short-lived, as the Philippine–American War soon followed. In 1899, Santo Tomas became a center of resistance against American forces. Guerrilla Unit No. 5, under the leadership of Captain Santiago Fontanilla, operated in the areas of Santo Tomas, Agoo, Aringay, and Tubao.

The guerrilla forces played a crucial role in resisting American advances and defending the town's autonomy. On November 18, 1899, American troops arrived in coastal La Union via Rabon Point after successfully taking Pozorrubio and San Fabian in Pangasinan under General Samuel Baldwin Marks Young. This led to a decisive battle along the coast of Santo Tomas and nearby Tubao. By November 19, the Americans had taken control of Santo Tomas and Agoo, and by November 20, they had captured the revolutionary headquarters in San Fernando.

By May 1, 1901, the General Manuel Tinio Brigade surrendered to the Americans, marking the end of the Philippine-American War in La Union and the surrounding region.

Under the American regime, the local administration transitioned to a new system where municipal presidents replaced the previous capitanes. Don Bruno Pacho was appointed as the first Presidente Municipal of Santo Tomas, serving until 1901. Several successors followed, with Don Eusebio Tabora as the last municipal president under the American administration.

By 1903, the Philippine Commission reorganized the administrative and territorial structure of municipalities across the country. Due to sparse population and financial challenges, smaller municipalities were merged. As a result, Santo Tomas was integrated with Agoo. However, on January 1, 1908, Executive Order No. 41 restored Santo Tomas as an independent municipality.

Japanese Occupation When World War II broke out in 1941, Japanese soldiers landed along the shores of Santo Tomas on 22 December 1941. This temporarily ended American rule in the town.

Under Japanese occupation, the municipal government was reorganized, and municipal mayors were appointed as heads of the town. Don Moises Villanueva became the first municipal mayor under Japanese rule in 1942. Four municipal mayors served during the Japanese occupation, with the last being Don Venacio Paculan, whose term ended a day after American forces landed along Lingayen Gulf on January 14, 1945, to begin the liberation of Luzon.

Post-War Era After World War II, Santo Tomas underwent significant reconstruction and development. The town’s agricultural industry, particularly tobacco and rice production, remained a cornerstone of its economy. Efforts to rebuild infrastructure, including roads, bridges, and schools, were prioritized, contributing to the town's recovery and modernization.

When the Commonwealth government was re-established, President Sergio Osmeña reorganized various municipal units. Don Eusebio Tabora was reappointed as the first post-liberation municipal mayor of Santo Tomas.
