According to the 2024 census, it has a population of 164,020 people, making it the most populous city in the province and the second most-populous in Cagayan Valley after Tuguegarao. As of 2025, it also had the highest number of voters in the province, with 105,526 voters.

It is dubbed as the corn capital of the Philippines, and the home of the country's largest armchair locally known as butaka.

Etymology

According to Fr. Julian Malumbres, Ilagan derived its name from the word laga, an Ibanag word for "smallpox", of which there was an outbreak during the town's founding in 1686.

History

::quote

Early history

The town was then called by its native Gaddang settlers as Bolo during the pre-Spanish conquest era. It was one of the populous settlements during that period and the site of the vast tobacco plantation in the region making it one of the most important economic areas in northern Luzon.

Spanish colonial era

In 1581, Governor-General Gonzalo Ronquillo de Peñalosa sent Capt. Juan Pablo Carreon to explore Cagayan Valley as well as to establish missions. Among the Spanish missionaries who penetrated deeply into the region was Pedro Jimenez, who founded Ilagan.

The town of Bolo was founded by the Dominicans in 1619 in honor of Saint Ferdinand of Castile. The old Bolo was situated on the western side of Cagayan River in what is known today as Naguilian-Baculod. The cultural shock brought by the dominating social and economic regulations introduced by the Spanish authorities propelled the natives to dissent in the Mallig and the Ilagan-Tumauini territories in what was known as the Gaddang Revolution. The natives abandoned their settlement after burning their church and houses until 1622 when the Spanish government pardoned and exempted them from paying tribute within three years. After the Gaddang revolt, the natives re-established their settlement upon the efforts of Fr. Pedro Jimenez in 1678 on the east side of the river thereby giving the legendary name for Ilagan which is the reverse of the word nagali meaning move or transfer. The Dominicans accepted the settlement as an ecclesiastical mission given the name San Fernando de Ilagan in honor of its patron, Saint Ferdinand of Castile.

Foundation

Main article: Municipalities of the Philippines

On May 4, 1686, Ilagan was founded and missionaries converted the natives to Catholicism. Ilagan was made the capital town of Cagayan Valley when Brig. Manuel Sanchez Mira was then the governor of the whole territory.

In 1763, Ilagan was the scene of the revolt led by Dabo and Juan Marayag against the collection of tribute, the enforcement of tobacco monopoly committed by the friars during the Spanish colonization.

On May 1, 1856, Ilagan became the capital town when Isabela de Luzon was founded.

American colonial era

Present-day Ilagan is an area that was detached from the old province of Nueva Vizcaya. The first municipal president of the town, Rafael Maramag, added luster to the history of his hometown by becoming the first governor of the province of Isabela after its reorganization by the Americans in 1901.

On August 4, 1901, the American occupation under the United States-Philippine Commission enacted the Provincial Government Act 210 that re-established Isabela and other provinces in the Philippines. Rafael Maramag, a former municipal president (mayor) of Ilagan was appointed as the first governor. The act then re-established Ilagan as the provincial capital.

On November 13, 1925, Gaffud approved a resolution filed by all Municipal Presidents of the Isabela (the counterpart of the present-day Mayor's League) following a four-day convention. The resolution called for the erection of a monument in honor of the country's National Hero José Rizal in the public plaza.

Japanese occupation

The fortunes of Isabela as a province and Ilagan as a town followed a similar path to the rest of the country's history as a commonwealth nation and as a free republic in 1942, the Japanese occupation, liberation, political and military independence to this day.

On June 19, 1945, Ilagan was liberated from the Japanese Army as part of the liberation campaign with the combined forces of 14th Infantry, United States Army Forces in the Philippines – Northern Luzon (USAFIP-NL), under the command of Lt Col. Romulo A. Manriquez, and the 37th Division of the U.S. Sixth Army against the Japanese.

During this era, a man-made tunnel was constructed from the sweat and blood of detained Ilagueños and it is now a tourist destination in the city. The tunnels are believed to have served as headquarters of the Japanese soldiers.

The Postwar era

By the turn of the 1950s, the new Poblacion was located uphill from the old Saint Ferdinand Parish Church, formerly known as Saint Ferdinand Cathedral in Bagumbayan to San Vicente, which is the site of the current City Hall.

The Martial Law era

When Ferdinand Marcos' September 1972 declaration of Martial law began 14 years of authoritarian rule, the province of Isabela, including the municipality of Ilagan became a center of both conflict and protest when Marcos cronies Danding Cojuangco and Antonio Carag managed to block a Spanish-era grant which was supposed to see the return of Hacienda San Antonio and Hacienda Santa Isabel in Ilagan to local farmers. Cojuangco and Carag purchased the two haciendas themselves, displacing tens of thousands of farmers who were supposed to get those lands back a hundred years after the Spanish acquired them.

In its desire to serve its parishioners, the Roman Catholic Diocese of Ilagan hosted a Social Action Center which would help the farmers. In the Social Action Center's newsletter, the "Courier," researcher Sabino Padilla Jr. documented and exposed the ways by which Cojuangco, Carag, the provincial government, and the military harassed the farmers who were supposed to get the land. This all led to a protest march in joined by 12,000 protesters from all over Isabela, and eventually, for 4,000 farmers to finally get the titles to their land. But it also earned the ire of the administration.

In 1982, Padilla and 12 others were arrested by the regime and jailed under poor conditions at the Bayombong, Nueva Vizcaya Stockade of the Philippine Constabulary until almost the end of the Marcos regime.

In 1983, soldiers went as far as to raid the residence of the Bishop of Ilagan, Miguel Purugganan, in search of alleged rebels and firearms. They found none but continued to keep Bishop Puruggananan and the church workers under him under military surveillance.

Cityhood

Main article: Cities of the Philippines

On February 2, 1998, congress passed Republic Act 8474 which sought to convert Ilagan into a city. But the plebiscite held on March 14, 1999, turned down its bid for cityhood. The majority of the people voted no in that event under the mayoralty of Mercedes P. Uy.

On March 2, 2005, House bill no. 3847 was filed and approved by the house and transmitted for the cityhood of Ilagan but remained pending concurrence in the senate. The bill did not go through when mayor Delfinito C. Albano was gunned down by three unidentified men in the night of June 27, 2006, in Quezon City. The campaign used the term C-U-DAD Ilagan for the cityhood status of Ilagan.

On February 27, 2012, Ilagan renewed its bid for cityhood as sponsored by House bill no. 5917. Local officials of the town expressed support for the town's conversion into a city. On May 22, 2012, the congress approved the cityhood bill of Ilagan on its House resolution no. 144 and was signed by then President Benigno Aquino III on June 21, 2012. Plebiscite was held on August 11, 2012, with a majority of votes voting yes under the leadership of Josemarie L. Diaz. By virtue of Republic Act 10169, Ilagan was then proclaimed as a new component city, the third in the province of Isabela and the fourth in Cagayan Valley on the same day by COMELEC Commissioner Armando Velasco.

Contemporary

On August 28, 2019, the city government created the Ilagan Development Authority (ILAGANDA) which is aimed to transform Ilagan into a liveable city in the year 2030.

On November 25–26, 2023, the City of Ilagan hosted the biggest and largest serbisyo caravan in the country, the Bagong Pilipinas Serbisyo Fair held at the City of Ilagan Sports Complex and Isabela National High School. The event saw the first time that the BPSF program went to Cagayan Valley, marking its eighth installment nationwide. With the aim of the national government delivering quality services closer to clients. Among the lined-up activities are Rise Up Financing, Online Business Name Registration, Barangay Micro Business Name Registration, One Town, One Product (OTOP) Mini Fair, Diskwento Caravan, Product Standard Showcase, and Negosyo Center Business Counseling Services. Under the initiative, Isabela residents received P152 million worth of cash, while a total of P500 million went to programs and services. The program benefited at least 100,000 recipients, with a total of 26 government agencies participating in the event, providing over 195 services.

Among the services included is the Department of Social Welfare and Development’s (DSWD) Assistance to Individuals in Crisis Situations (AICS) program, which provided a provincial wide payout in the three cities and 34 municipalities of the province of Isabela. AICS assisted more than 42,000 individuals amounting to a total of P140 million in payout which included assistance for Agrarian Reform Beneficiaries (ARBs), Persons with Disabilities (PWDs), Indigenous Peoples (IPs), teachers, the transport sector, and fishermen; and collaborate with partner agencies.

The BPSF also included other province-wide activities such as scholarship programs from the Technical Education and Skills Development Authority (TESDA) and the Commission on Higher Education (CHED). Other activities included livelihood assistance for various sectors in pre-identified eligible recipients across Isabela. The Department of Health (DOH) shared their Lab for All program, or the giving of free medical services closer to the people. While the Department of Agriculture (DA), spearheaded the distribution of financial assistance for farmers, seeds and fertilizers, and farm equipments and machineries.

Products of farmers and fishermen were also on sale through the KADIWA ng Pangulo as a way to promote locally produced products. All of the products displayed were made affordable, fresh, and pesticide-safe for the consumers. The Bureau of Fisheries and Aquatic Resources (BFAR) also turned over fish cages, fish feeds, and fingerlings for the distribution and sale of seafood. Agencies like the Department of Agrarian Reform (DAR), Department of Labor and Employment (DOLE), Department of Science and Technology (DOST), Department of Environment and Natural Resources (DENR), Philippine Coconut Authority (PCA), National Food Authority (NFA), and the Public Attorney’s Office (PAO) also provided livelihood, legal, and other relevant social services to the recipients. Other regulatory functions of the Philippine National Police (PNP), Department of Foreign Affairs (DFA), Land Transportation Office (LTO), National Bureau of Investigation (NBI), Philippine Statistics Authority (PSA), Professional Regulation Commission (PRC), Social Security System (SSS), PhilHealth, Government Service Insurance System (GSIS), and the Bureau of Internal Revenue (BIR) also extended their programs and services during the two-day caravan.

Demographics

Ethnicity

Ilagueños today reflect a combination of indigenous, Chinese, and Hispanic descent. The core community was composed of tribes notably the Agta, Ibanag, Gaddang, Yogad, and Kalinga which mirrors the habitation of the Philippines believed to have started 26,000 years ago with various strains of Aetas, then Indonesians coming 5,000 years ago and the Malays in droves starting 200 years B.C. up to 1500 A.D. Trade and cultural relations with Chinese preceded the 16th-century incursion of the Spaniards. Ilocanos who already developed their own distinct traits were recorded to have migrated massively in the 19th century owing to the accessibility of the land and vast opportunities in the area straddling the present-day provinces of Cagayan and Nueva Vizcaya. It was proclaimed a province by a Royal Decree and named Isabela de Luzon on the first day of May in 1856.

Languages

There are three native languages in Ilagan: Ibanag, Ilocano, and Tagalog, which make it a multilingual city. English is used primarily in communication for government publications, local newsprints, road signs, and commercial signs, and in doing official business transactions in the city.

Population

As of the 2024 census, the population was 164,020 people, with a density of {{sigfig|164,020/1,166.26|2}} PD/km2. Imelda Bliss Village remains the most populous barangay with 7,961 people while Carikkikan Sur is the least populous with just 223 people.

The rapid increase of the population in Ilagan is attributed to the current growth of economic activities especially in the sectors of Commerce, Industry, Agriculture, and Housing. Ilagan is one of the emerging cities in the Philippines with more than 100,000 residents. Statistics from the Philippine Statistics Authority show that Ilagan had a population 131,24311 in 2007, which increased to 135,174 people in the 2010 census making Ilagan as the most populous city in the province of Isabela and the second in Cagayan Valley after Tuguegarao.

Religion

Main article: Religion in the Philippines

Catholicism

Ilagan's population is predominantly Roman Catholic. The Diocese of Ilagan has 39 catholic churches all over the province of Isabela. Its former seat was in Saint Ferdinand Parish, then it is now transferred to the Cathedral of Saint Michael the Archangel in Gamu, Isabela. The Saint Ferdinand Parish was built in a baroque style in 1612and is located in barangay Bagumbayan.

Others

There are also Protestants, Baptist, Church of Christ, Adventists, Born Again groups, Victory Christian Fellowship, Latter Day Saints, Jehovah's Witnesses, Islam, and Philippine-based groups like Iglesia ni Cristo, and Members Church of God International (MCGI) that account to the city's population. These religious organizations have their own temples and churches sparsely located in the city.

Economy

At present, Ilagan has been one of the fastest-growing economies in the province of Isabela as well as in the whole Cagayan Valley over the past years. The city is the primary growth center and investment hub of the region due to the rapid commercialization and stabilization of the different sectors involved in its economy.

The transformation of Ilagan into a fast-growing city in Cagayan Valley became evident upon the assumption into office of then Mayor Josemarie L. Diaz, the re-structuring of the economic landscape of the city and the eventual transformation of its business climate into a business-friendly environment successfully lured multi-national companies in investing their capitals into its market. The economic boom began to engulf Ilagan with the entry of eight banks and financial institutions in just several months.

The Local Government of Ilagan responded positively to these developments by the enactment of legislative measures including the provision of the Investment Incentive Code which provided for tax incentives to investments.

City symbols

::figure[src="https://upload.wikimedia.org/wikipedia/commons/0/05/Ph_seal_Ilagan.png" caption="City Seal of Ilagan"] ::

The city seal has an inscription of the city name "City of Ilagan" and the name of the province "Isabela" with the year 1686 as the foundation of the town and 2012 as the year of its cityhood declaration on a dark blue ring.

Within the ring, located at the upper-left portion, is a mountain representing the Sierra Madre mountain ranges, the longest mountain ranges in the Philippines. Nearby are two rivers representing the Cagayan River and Ilagan River, showing that the Ilagan River flows westward from the Sierra Madre, joining the Cagayan River. The people near the center, colored yellow, represent the city's citizens, with the overlapping buildings and red gear representing city urbanization, and the municipal logo placed inside the gear as an homage to the city's past.

Near the upper-right are various agricultural symbols: a carabao horn (representing the prevalence of carabaos in the local farming industry), a kamote or sweet potato (a major local root crop), maize (a major local crop representing the city's title as the Corn Capital of the Philippines), and a stalk of palay or unharvested rice (another major crop in the city, representing the city as a part of Asia given its nature as a staple food in the continent).

Another inscription is written at the bottom of the seal's inner portion: the Latin phrase Vox populi, Vox Dei, meaning "the Voice of the People, the Voice of God."

The city's barangays also have their own seals which represent themselves.

::figure[src="https://upload.wikimedia.org/wikipedia/commons/b/bd/Flag_of_Ilagan,_Isabela.png" caption="City Flag of Ilagan"] ::

The city flag, like many LGU flags in the Philippines, is a "seal on a bedsheet" (a derogatory term in Vexillology that refers to flags that use a solid color background with the seal of what the flag represents placed on top). More specifically, the flag has a background of light blue or azure (the de facto city color of Ilagan) with the city seal on top.

The city flag has no official aspect ratio, although it is commonly reproduced with either a 1:2 ratio (like that of the Philippine national flag) or a 2:3 (like most other flags).

The current city anthem or hymn is the City of Ilagan Hymn, composed by Ato Del Rosario and lyrics by Nilo Agustin. According to the city's Facebook page, the new hymn was inspired by the incumbent city mayor, Hon. Josemarie L. Diaz. Although well-received, it does not yet seem to have widespread adoption for flag ceremonies in public schools like the former anthem did.

The former city anthem was the Martsa ng Ilagan (), composed by Rev. Fr. Ingeno Rapadas.

The city, being called the Corn Capital of the Philippines is often symbolized by corn, making it Ilagan's de facto city crop.

As mentioned previously, light blue or azure is a de facto city color. Golden yellow or maize yellow is also a de facto city color, with both colors often being used by the city government across the city (especially on the sidewalks and poles along the national highway).

Bridges

One of the longest bridges is the Malalam Bridge which was inaugurated on December 8, 1995.

Baculud Overflow Bridge was inaugurated in 2014 that connects the Poblacion area to the northeastern barangays going to Tuguegarao. In 2016, the structure was damaged by flood brought by the torrential rain when Typhoon Haima or locally known as Super Typhoon Lawin struck the provinces of Isabela and Cagayan. The authorities had to close the bridge until the completion of its rehabilitation which began in 2017. On May 4, 2019, the two-lane overflow bridge was reinaugurated by the city government during the 333rd founding anniversary of Ilagan.

It connects the city's western barangays and nearby municipalities of Delfin Albano and Tumauini. Before the construction of the new bridge, residents have to use barges to transport agricultural products to the market. Due to this, travel time between barangays on either side of the river has been cut short drastically.

The Santa Maria (Cabisera 8) bridge was completed and opened to the public in 2015. Road concreting and widening, creation of diversion and circumferential roads and farm to market roads were prioritized by the national and city government to help mobilize the transportation goods and delivery of basic services within the city's jurisdiction and neighboring municipalities.

Accordingly, it is a pure solar PV Grid-connected installation that will avail of the privileges under the Renewable Energy Law of the country. The renewable energy to be generated will be sold directly to the National Grid Corporation of the Philippines (NGCP) under the Feed-in-Tariff Scheme of the RE law. The 100.0 MW Solar PV project will help alleviate the current electricity shortage in the country that causes regular blackouts resulting in industry closures as well as inconvenience to the consumers. The solar power facility will be constructed on a 100-hectare land, several kilometers away from the city proper.

In December 2022, the Department of Energy (DOE) has given the go signal to a Filipino-French joint venture to develop one of the biggest renewable energy projects in the Philippines - an ₱18-billion solar farm in Ilagan City. The project will be undertaken by San Ignacio Energy Resources Development Corporation, which is part of the Nextnorth Energy Group developing over 450 megawatts of solar and hydro projects in Northern Luzon, and French firm Total Eren S.A.
