Naguilian, officially the Municipality of Naguilian (Ilocano: Ili ti Naguilian; Filipino: Bayan ng Naguilian), is a 1st class municipality in the province of La Union, Philippines. According to the 2020 census, it has a population of 52,189 people.^[3]

Naguilian is 40 kilometres (25 mi) from Baguio via the Naguilian Road, 17 kilometres (11 mi) from the provincial capital, San Fernando, and 266 kilometres (165 mi) from Manila.

Originally a part of Bauang in the province of Pangasinan, Naguilian derived its name from the Iloko phrase “Nag-ili-an dagiti gan-ganaet” meaning “a place where people from other places come to stay”. It is formed from the Iloko root word “ili” meaning “town” which was later modified as “Naguilian”.

Its separation from Bauang coincided with the centennial celebration of the Catholic Church of Naguilian in 1839. When La Union was created by a Royal Decree in 1850, Naguilian was one of the twelve (12) towns that comprised the province.

Due to increasing population density, a group of immigrants drifted to the shore of La Union and began building the town of Bauang at the south of the river and settled thereat. Later, however, due to population explosion, they followed the meander of the river in search of a new territory. They found a fertile valley at the bank of the river, which they called Naguilian. They built a colony at the fork of the two (2) rivers and began developing the territory. They were the first inhabitants of Naguilian.

Records have shown that when the Ilocanos arrived in town, Igorot settlers are already at par. At present, “natives” as the Igorots are popularly called can still be found at the southern and northern parts of the town while majority of the Ilocanos are settled at the lowlands.

During its establishment as a town, it was believed that a few portions of Burgos and Bagulin were originally a part of Naguilian. These include the lower portion of Burgos known as “Disdis” meaning “a small barrio” and the barangays along the southwestern bank of the Naguilian River (Bagulin portion). “Disdis” was also called “Stancia” by the Spaniards as it served as a pasture ground for their horses while the portion which eventually became a part of Bagulin was predominantly inhabited by the Igorots.

However, during the American Regime, by virtue of a Resolution of the Provincial Government of La Union, Naguilian was divided into three portions namely, that portion which became the town of Naguilian, that portion forming part of Burgos and that portion forming part of Bagulin.

The earliest political system used during the Spanish colonial period was the “encomienda” system. Under this system, the native inhabitants in a given geographic region were entrusted to conquistadores, friars, and native nobles in exchange for their services to the King. In return, the person granted the encomienda, known as an encomiendero, were given the privilege to collect tribute from its inhabitants and to provide military protection, justice and governance. The encomienda system however was abused by encomienderos and by 1700 was largely replaced by administrative units. With the main purpose of governance and tax collection, small towns or pueblos were ruled by Gobernadorcillos and Capitanes.

Naguilian is characterized by hills and mountains that are gently rolling, bordered by the Cordillera Mountains in the east. The alienable lands are rolling plains in narrow strips, framed by the mountains slopes and the banks of rivers, crisscrossed by streams and springs from the side of the mountains. Its soil varies from clay loam to sandy loam and golds.

There are two major rivers in Naguilian. The Naguilian River is located in the western portion of the town. It flows westward beginning from the province of Benguet towards La Union and empties into the South China Sea, draining the valleys of Barangays Bimmotobot, Mamat-ing Sur, Mamat-ing Norte, Tuddingan, Gusing Sur, Gusing Norte, Baraoas Norte, Daramuangan, Dal-lipaoen, Cabaritan Sur, Ortiz, Natividad, Suguidan Norte, and Suguidan Sur. It has a length of approximately 67 kilometres (42 mi) and has a basin area of 658 square kilometres (254 sq mi). As classified by the Environmental Management Bureau, the upper reaches of the river falls under Class A which means that it is suitable as water supply source for drinking. The lower reaches have lower water quality, categorized under Class C.

The other major stream springs from the Municipality of Burgos and drains the valleys of Barangays Aguioas, Sili, Al-alinao Norte, Nagsidorisan, Angin, Suguidan Norte, and Natividad. These two rivers meet at the poblacion where it forms a delta, then meander through the center of the municipality and empty at the mouth of the river in Bauang.

The municipality's climate falls under the first type of climate in the Philippines, characterized by two (2) distinct seasons, wet and dry. The wet season usually comes in May and ends in the early part of October. The rest of the year is dry season.

Built-up areas of the town are generally spread along the barangay roads. Of the total land area, 50 hectares (120 acres), equivalent to 0.50% of the total land area, are classified as built-up areas. Urban built-up area, totaling 18.90 hectares (46.7 acres), constitute 11.22% of the total urban land area. Rural built-up areas total 31.10 hectares (76.8 acres), or 0.31% of the total rural area.

Through Proclamation No. 52, a portion of Barangay Casilagan, with an area of 897.26 hectares (2,217.2 acres), was proclaimed as a watershed area by the Bureau of Forestry.^[6] This is equivalent to .10% of the total land area of the town.

Naguilian is politically subdivided into 37 barangays. ^[7] Each barangay consists of puroks and some have sitios.

In the 2020 census, the population of Naguilian was 52,189 people,^[3] with a density of 500 inhabitants per square kilometre or 1,300 inhabitants per square mile.
