The town was then called by its native Gaddang settlers as Bolo during the pre-Spanish conquest era. It is one of the populous settlement during that period and site of the vast tobacco plantation in the region making it one of the most important economic areas in northern Luzon. Shortly after Juan de Salcedo conquered Northern Luzon in 1587, Gov. Rodrigo de Penalosa sent Capt. Pablo de Carreon to explore Cagayan Valley as well as to establish missions in towns. Among the Spanish missionaries who penetrated deeply into the region was P. 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 in the western side of Cagayan River in what is known today as Barangay 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 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 "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.
On May 4, 1686, Ilagan was founded and missionaries converted the natives to Christianity. Ilagan was made the capital of Cagayan Valley when Brig. Manuel Sanchez Mira was then the governor of the whole territory. Ilagan was the scene of the 1763 revolt in Isabela led by Dabo and Marayag against the collection of tribute, the enforcement of tobacco monopoly committed by the friars during the Spanish occupation. Upon the separation of Isabela on May 1, 1856, Ilagan became the capital of the province.
On August 4, 1901 the American occupation under the United States-Philippine Commission has enacted the Provincial Government Act 210 that has 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 has approved a resolution filed by all "Municipal Presidents of the Isabela" (the counterpart of the present-day Mayors' 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 old Ilagan public plaza in Barangay Bagumbayan. 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 Barangay Bagumbayan) to Barangay San Vicente; site of the current City Hall.
Incorporation as a city
Ilagan has attempted to gain cityhood status at least five times in its history:
- During the Spanish colonization period, Ilagan applied to gain cityhood status from the Spanish Government but was unsuccessful. Ilagan could have been the second city of the Philippines after Nueva Segovia, now Lal-Lo, Cagayan.
- During the administration of then Mayor Paguirigan, but was shelved during the American occupation.
- On February 2, 1998, congress passed Republic Act No. 8474 which sought to convert Ilagan into a city. But the plebiscite held on March 14, 1999 turned down its bid for cityhood under the administration of then Mayor Mercedes P. Uy. The majority of the people voted no in that event.
- During the administration of then Mayor Delfinito "Jojo" C. Albano, Ilagan's cityhood status did not push through when the mayor was gunned down by three unidentified men in the night of June 27, 2006 in Quezon City. Mayor Albano used the term C-U-DAD Ilagan for campaigning the cityhood status of Ilagan.
- In 2012, the leaders of Ilagan, led by then Isabela 1st District Representative Rodolfo Albano Sr., renewed its bid for its cityhood. Former Isabela Vice Governor Rodolfo T. Albano III said that, "The provincial government fully supports Ilagan’s renewed cityhood bid, considering that such goal is already long overdue". Former Department of Justice Secretary Silvestre Bello III expressed support to the renewed move of the local officials of Ilagan, Isabela, headed by then Mayor Josemarie L. Diaz, 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 His Excellency, then President Benigno Aquino III. Plebiscite was held on August 11, 2012, with a majority of votes voting "yes". 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.
On August 11, 2015, marked another day in the history of Ilagan as the Department of Agriculture proclaimed the city as the new Corn Capital of the Philippines during its third cityhood anniversary. Former Sec. Proceso Alcala was represented by then Asec. Edilberto M. De Luna who travelled all the way to Ilagan to attend the momentous event.

In the 2015 census, the population of Ilagan, was 145,568 people, with a density of 120 inhabitants per square kilometre or 310 inhabitants per square mile.
The rapid increase of population in Ilagan is attributed to the current growth of economic activities specially in the sectors of Commerce, Industry, Agriculture and Housing. Ilagan is one of the 145 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.
Ilagan's population is predominantly Roman Catholic. The Diocese of Ilagan has 39 catholic churches all over the province of Isabela. 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 Ang Dating Daan that accounts to the city's population. These religious organizations have their own temples and churches sparsely located in the city. Some Ilagueños were converted to Islam where their mosque is found in Barangay Baligatan.
Agriculture and fishery remains to be the main backbone of Ilagan's economy. There are almost 23,803 hectares that are basically cultivated land and 314 hectares are utilized for fish culture. However, the suitable farm area of Ilagan is 32,153.19 hectares potentials for crops, livestock and fish production. This figure shows that a significant percentage (24.99%) is not being fully utilized for agricultural production leaving them idle and under utilized.
Commerce and trade is the second economic based income of the people of Ilagan. In the year 2006, statistics showed that there are currently 1,795 registered business establishments. For year 2000, commercial trade was at 1,996 revealing that there were more or less than 201 establishments that had been closed down within the period 2000–2006. There were even more establishments in 1995 with a total of 1,877 in all. The trend shows that from 1995 to 2000, there was a growth of 2.94%, but from 2000 to 2006 a decreasing growth rate of -1.75% was registered. Just like the past years, for the year 2006, commercial activities within the municipality are classified into wholesale, retail and service-oriented businesses.
The industrial sector of the municipal economy comprises 210 establishments in year 2006 as compared with 207 in 2000. This reflects a 2.4% increase in industrial activities over a period of six years (2000–2006). The existing industries are mostly on a micro scale except for the Coca-Cola Bottlers Philippines, Inc. located in Barangay Guinatan which is the only significant employment generator within the locality at that time. Following the previous year’s trend, industries currently operating are agro-industries, wood-based manufacturing or service-oriented industries.
The commercial area includes areas which are occupied by public markets, wholesale and retail stores, restaurants, banks, shops and other establishments or structures engaged in commercial activities. The bulk of those who are engaged in trade and commerce are found in the public markets. The area covered by the commercial area is approximately 90.56 hectares or 2.62% of the urban core.
As compared to the 2000 existing commercial area of 17 hectares, the increase of 73.56 hectares in 2007 is an indication that Ilagan is racing towards commercialization.
The transformation of Ilagan into a fast growing municipality in Cagayan Valley became evident upon the assumption in office of then Mayor Josemarie L. Diaz, the re-structuring of the economic landscape of the municipality 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. Economic boom began to ingulf Ilagan with the entry of eight (8) banks and financial institutions in just a number of months.
The Local Government of Ilagan responded positively with these developments by the enactment of legislative measures including the provision of the Investment Incentive Code which provided for tax incentives to investments. These measures eventually opened the flood gates for big investments to enter the local market that included the establishments of malls like the Northstar Mall and Talavera Square Mall that house the Savemore, Robinsons Supermarket, Puregold, Jollibee, McDonald's, Red Ribbon, Goldilocks, Mang Inasal, Greenwich, Chowking and many other stores.

It has two major public markets which is the old Pamilihang Bayan ng Ilagan located in Centro Poblacion (now called Xentro Market) and the multi-million pesos New Ilagan Public Market Complex in Barangay Baligatan. In front of the public market is a three-storey structure called as Ilagan City Mall, the first LGU-owned and operated mall in the city. The increasing number of market goers coming from the different regions of the city and adjacent municipalities, prompted city officials to facilitate the construction of the modern market. Ilagan is home to eighteen (18) banks which is primarily composed of universal, commercial, savings and rural banks.

Pawnshops, lending companies, insurance agencies, cooperatives and other financial institutions are spread all over the city.

Ilagan became one of the largest producers of tobacco during the Spanish time. The Tobacco Monopoly have caused the valley to languish in poverty from 1785 to 1797. The lifting of the monopoly was caused by the heavy loss incurred by the government. A Royal Decree released in 1882 totally abolished the monopoly and attracted foreign capitalist to invest in the country. In Ilagan, the Compania General de Tabacos de Filipinas or the Tabacalera was established in 1881 and produced the famous La FLor de Isabela which was the largest company of its kind in the world at that time. The Tabacalera acquired two haciendas in Ilagan: the Hacienda San Antonio and Hacienda Sta. Isabela.

Ilagan is linked by a national highway called Maharlika Highway (designated as Asian Highway 26, AH26 by Asian Highway Network) The highway starts at Barangay Alibagu and ends at Barangay San Juan. On-going road constructions are the Ilagan-Divilacan road and the Ilagan-Delfin Albano-Mallig Road which are expected to be completed in five years and the former later this year 2013. Ilagan's longest bridge is the Malalam Bridge in Barangay Malalam going north.
In 2014, the city government inaugurated the Baculud Overflow Bridge that connects the poblacion area to the northeastern barangays going to Tuguegarao. However, 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 rehabilition which began in 2017. On February 19, 2015, the Lullutan Bridge was opened to the public local by the local government. On April 7, 2015, then President Benigno S. Aquino traveled to Isabela to lead the inauguration of the new bridge, which connects the east and west banks of the Cagayan River. It is expected to connect 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. With its completion, residents would no longer have to pay barge fees, and travel time between barangays on either side of the river has been cut short drastically. The bridge in Sta. Maria (Cabiseria 8) was completed and opened to the public in 2015. Road concreting and widening, creation of diversion and circumferencial 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.
The construction of an 82-kilometer Ilagan-Divilacan Road through the protected Sierra Madre mountains is on-going to open access to the coastal towns of Divilacan, Palanan and Maconacon. The approved budget contract of the project amounting to P1.5B, will pass through the foothills of the 359,486-hectare Northern Sierra Madre mountain ranges and will take four years to complete. The project will improve an old logging road used by the defunct Acme Logging Corp. until the 1990s. It will start in Barangay Sindon Bayabo in Ilagan and will end in Barangay Dicatian in the coastal town of Divilacan. The project is started in March 2016 and it will be completed in 2021.
There are 29.313 kilometres (18.214 mi) of concrete road out of 24.56 kilometres (15.26 mi) of national road that passes through the city.
