History

The province of Isabela used to be a vast rainforest where numerous indigenous ethnolinguistic groups lived. Many of the same ethnic groups still live in the province.

To commemorate this historical event, in 1962 the town officials constructed a monument by the Palanan City Hall, right on the spot where General Aguinaldo was captured, to memorialize the historic event. The monument was inaugurated on June 12, 1962, Philippine Independence Day, and still stands. Isabela was re-organized as a province under the American military government through ''Act No. 210'', passed August 24, 1901. The Americans built schools and other buildings and instituted changes in the overall political system. However, the province's economy remained predominantly agricultural, with rice replacing corn and tobacco as the principal crop.

stagnated the province's economic growth but it recovered dramatically after the war. In 1942, Imperial Japanese forces occupied Isabela. In 1945, the liberation of Isabela commenced with the arrival of the Philippine Commonwealth troops under the 11th Infantry Regiment, Philippine Army, USAFIP-NL and the recognized guerrillas attacked by the Japanese Imperial forces in World War II. A new wave of immigration began in the late 19th and 20th centuries with the arrival of the Ilokano who came in large numbers. They now constitute the largest group in the province, and it was only in this large-scale Ilocano immigration & settlement that made Ilocano language replaced Ibanag as the ''lingua franca'' of the province. Other ethnic groups followed that made Isabela the "Melting Pot of the Northern Philippines".

During the Marcos dictatorship

By the first term of the presidency of Ferdinand Marcos, Isabela had become known among students activists for its remoteness and the poverty of its agricultural workers, making it a favorite destination for "dissatisfied, alienated young activists." So when the Communist Party of the Philippines (CPP) was established in 1968 after splitting from the largely-defeated old Communist Party (

. The actual size of the NPA at the time was very small, reportedly with only 60 guerrillas and 35 WWII-era guns as of 1969. But Marcos hyped up its formation, supposedly because this would help build up political and monetary support from the US. The Armed Forces had a number of initial successes against the NPA in Isabela at this time, including the discovery of the Taringsing Documents in Cordon outlining plans for a communist takeover; and the failed landing of arms bound for the NPA in Palanan during the MV Karagatan incident in 1972. These incidents were cited as some of the justifications for the declaration of

Two of the major detention centers for political detainees located in Isabela were Camp Melchor F. dela Cruz in Barangay Upi in Gamu, in which officers of the Armed Forces Northern Luzon Command were also stationed; and the Headquarters of the Isabela Province Philippine Constabulary in Barangay Baligatan, Ilagan.Panaglagip: The North Remembers – Martial Law Stories of Struggle and Survival Edited by Joanna K. Cariño and Luchie B. Maranan. renamed Camp Lt. Rosauro Toda Jr. in 2020. The province of Isabela became a particular 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

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. In 1985, three councilors from Barangay Ibujan in the municipality of San Mariano, including Ibanag community leader Luis Gabriel who had rejected overtures for the establishment of a local CHDF base in the town, were forcibly taken by heavily armed men who claimed that they needed the three as guides. However, the three were never seen again, and they eventually became counted among the many desaparecidos during the Marcos dictatorship. It was also during the dictatorship that Marcos began awarding logging concessions to his cronies in the areas of the Sierra Madre region, which heralded the beginning of widescale deforestation and other environmental problems that affect the province since then, despite Marcos creating the Palanan Wilderness Area in 1978 which was later expanded by President Fidel V. Ramos to become the Northern Sierra Madre Natural Park in 1997. In 1975, construction began on the Magat Dam on the boundary of

Contemporary

Following the 1986 People Power Revolution, known as the current Fifth Philippine Republic, under the 1987 Philippine Constitution, various changes have been attempted since then in the province. Dy Sr. was succeeded by his son, Benjamin G. Dy, in the gubernatorial seat from 1992 to 2001. Another Dy took over the gubernatorial seat in 2001 when Faustino Dy Jr. won the 2001 elections after having served as the district representative of the 2nd Legislative District of the province from 1992 to 2001. It was only in the 2004 elections that the family's control of the gubernatorial seat ended when Grace Padaca, a former journalist, won over Faustino Dy Jr. She was the first woman to serve as the governor of the province. After serving for six years (2004-2010), Padaca was defeated in the 2010 National Elections by Faustino "Bojie" G. Dy III who served as governor of the province for three consecutive terms (2010-2019). He was then succeeded by Rodolfo "Rodito" Albano III, a member of the Albano dynasty that dominates Isabela's 1st congressional district. In July 1994, the municipality of

In its second attempt to achieve cityhood, the campaign did not go through due to lack of concurrency in the

in 2006. Finally, Ilagan became a city, after its third move gained 96% of the votes in a plebiscite conducted on August 11, 2012. The night after the plebiscite, Ilagan was declared as a component city in the province by virtue of ''Republic Act 10169''. In 2001, the municipality of Cauayan became a component city in the province of Isabela through the ratification of ''Republic Act 9017''. In 2019, the province was reorganized into six districts, thereby increasing the number of legislative districts from four to six. Cities and municipalities were retained and others were reapportioned to the current district assignments.


2020 Ulysses Flood

Cagayan has been heavily impacted by changing weather pattern changes resulting from climate change, with the 2020 Ulysses flood being counted as one of the most severe examples. In November 2020, Typhoon Vamco (locally known in the Philippines as Typhoon Ulysses) crossed the country, dams from all around Luzon neared their spilling points, forcing them to release large amounts of water into their impounds including Magat Dam. The dam opened all of its 7 gates at , releasing over 5,037 cubic metres (1,331,000 US gal) of water into the Cagayan River flooding numerous riverside towns. Because there was very little media coverage of the flooding in the area in the wake of the COVID-19 lockdown in Luzon and the Shutdown of ABS-CBN broadcasting earlier that year, residents resorted to social media to request the national government for rescue. As a result of the catastrophe, the National Irrigation Administration (NIA) indicated that it would review its protocols regarding the release of water in Magat Dam and improve its watershed.

Government


Governors

After Isabela was re-organized as a province under the American regime in 1901, its first provincial governor was Rafael Maramag, a former Municipal President and also the first Municipal President of the capital town Ilagan. He was succeeded by his brother, Gabriel. Since 1969, the position has been occupied mostly by members of the Dy family, a political dynasty based in Cauayan that has expanded to neighboring municipalities. The current governor is Rodolfo "Rodito" Albano III, a member of the Albano dynasty that dominates Isabela's 1st congressional district and is an ally of the Dys.


Legislative districts

On September 27, 2018, ''Republic Act No. 11080'', an act reapportioning the province of Isabela into six legislative districts from four, was signed into law and the reapportioned districts elected its representatives starting in the 2019 midterm elections. Accordingly, the six districts are as follows: *First District: Cabagan, Delfin Albano, Divilacan, Ilagan City, Maconacon, San Pablo, Santa Maria, Santo Tomas, and Tumauini. *Second District: Benito Soliven, Gamu, Naguilian, Palanan, Reina Mercedes, and San Mariano. *Third District: Alicia, Angadanan, Cabatuan, Ramon, and San Mateo. *Fourth District: Cordon,

Economy

In terms of income classification, Isabela is rated as first-class province and considered among the richest and most progressive province in the Philippines and the most progressive in Region 02 courtesy of the three key cities strategically located in the province.


Trade and industry

Strategically located at the center of Cagayan Valley region, Isabela is acknowledged to have demonstrated strengths in business and industry. Thus, it has come to be known as the ''Regional Trade and Industrial Center'' of north-eastern Luzon. The province of Isabela is the richest in

last 2021. The cities of Cauayan, Ilagan, Santiago and the town of Roxas are the principal commercial centers of the province. Metro Manila-based malls and fast food chains have recently opened in these key trading hubs. To date, 192 banking branches operate in the province, with most of the universal and commercial banks providing automated teller machines for the convenience of their clients. Since the start of the 21st century, a growing number of foreign and local investors have selected Isabela as site of their business ventures. Heading the list are Isabela's top investors, namely: Mindanao Grains Processing Company, Inc., SN Aboitiz Power- Magat Inc., Universal Leaf Philippines, Coca-Cola Beverages Philippines, Inc., San Miguel Corporation, RC Cola and Pepsi Cola.


Agriculture

Agriculture is the biggest industry in Isabela. As the country's top corn producing province, it contributes 13.02% of the annual national yellow corn production. Asia's largest post-harvest corn processing facility, the Mindanao Grains, is located in the town of Reina Mercedes. As second highest rice-growing province nationwide, Isabela produces 15% of the aggregate national rice production on an annual basis. Being a surplus producer of the Filipinos’ staple crop, the province's rice sufficiency rate is at 224%, which means that Isabelinos produce more than they consume and are in fact responsible for supplying the rice requirements of Metro Manila and many other provinces. The unprecedented increase in palay production of Isabela made the province the ''Hybrid Rice Champion'' of the Philippines. High-value agricultural crops grown in Isabela include monggo, tobacco, coffee, banana, and mango. Its livestock and poultry industries are also on the rise, especially dairy processing, hog production, cattle breeding, and commercial poultry raising. Farming is highly mechanized as most of the agricultural lands are irrigated. With the presence of the Isabela State University, joint ventures and other foreign assisted projects and the Magat Dam contribute to the high productivity in agriculture. It is also the hub of trade and commerce and other economic activities due to its central location in the region. The wood industry used to be a top earner for the province but due to the logging ban imposed in the Cagayan Valley Region, activities in this industry considerably declined. However, furniture making using narra wood and other indigenous forest materials continue to exist. Isabela is one of the most progressive provinces of the Philippines having been adjudged as the most outstanding province on food security in the ''Gawad Sapat Ani Awards 2000''. For

Forestland

Forestland covers 54.37% or of Isabela's total land area of which 62% is protected forest and 38% is production forest. The best quality of
timber Lumber is wood that has been processed into uniform and useful sizes (dimensional lumber), including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing (floors, wall panels, window frames). ...
resources in the Philippines are found in Isabela's forests. Isabela's vast forest resources are now being ecologically managed to effect sustainable forest-based resource not only for the wood working industry but to secure a balanced ecosystem. The woodwork industry continues to operate under a regulated system, particularly the making of furniture using indigenous materials.


Fisheries

Isabela has a fertile fishing ground on the Pacific Coast. The Magat Dam reservoir is utilized for fish cage operations for tilapia production for domestic markets. Another thriving industry in the province is
aquaculture Aquaculture (less commonly spelled aquiculture), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. Nelu ...

neutral and sustainable. This biomass power facility is the first in the region and is designed to provide economical source of energy as well as job opportunities to residents of the host town/city. On 27 May 2015, the service contract of the largest solar PV power plant in the country has been approved by the Department of Energy (DOE). The P7-billion worth 100 MW Solar PV project in the city of Ilagan is designed to reduce the current shortage of electricity that causes regular blackouts that results to industry closures as well as inconvenience to the consumers. The solar power facility will be constructed at a 100-hectare land at Barangay Cabannungan, 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 P18-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. The project will involve the development of a 440 MWp/336 MWac solar PV project to be built on around 400 hectares of available land located along the Northern Luzon high voltage transmission network of the National Grid Corporation of the Philippines (NGCP). The project is scheduled to start construction in 2024 and start feeding electricity into the grid in 2025.


Transportation

Isabela is accessible by all means of transportation. Almost 180-kilometers of the Pan-Philippine Highway pass through the different towns and cities of the province. Several bus companies offer daily trips to different routes like Manila, Dagupan, Baguio, Ilocos, and vice versa. Public utility vans and small-time bus operators ply daily trips from Tuguegarao in Cagayan to Santiago City vice versa, while jeepneys and tricycles are commonly used as the basic mode of transportation within the province's jurisdiction.


Ilagan–Divilacan Road

The construction of an 82-kilometer route across the Sierra Madre National Park is intended to improve access to the province's three coastal communities - Divilacan, Maconacon, and Palanan. The project's authorized budget contract, worth P1.5 billion, will traverse the foothills of the Northern Sierra Madre mountain ranges, which cover 359,486 hectares. The idea is to rehabilitate an ancient logging route that was utilized until the 1990s by a defunct logging firm. It will begin in Barangay Sindon Bayabo in Ilagan City and end at Barangay Dicatian in Divilacan's seaside town. The project is scheduled to conclude in 2021. The secluded coastal settlements of Divilacan, Palanan, and Maconacon are frequently accessible only by boat or plane, making these difficult to reach at times of emergencies and calamities. There are no reliable road networks connecting Isabela's capital city to the coastal districts, denying locals access to basic commodities and social services such as health care. Once completed, the route is projected to bolster coastal economies, citing Divilacan's 119-hectare beach and freshwater areas that have attracted tourists. Resolution No. 11 of the Protected Area Management Board (PAMB) reclassifies areas of the Sierra Madre as a special-use zone. Additionally, the Agta and Dumagat communities in the vicinity have signed a memorandum of understanding with the provincial administration expressing their support for the road project. At least 1,800 Agta and Dumagat have made their homes in park areas. However, the road's impact on the protected forest has upset neighbors, who believe the project will harm the region's woods and ecosystems. The project has been delayed in recent years due to worries about the road's possible environmental impact. The Cagayan Valley Regional Development Council required that the road's proponents conduct a comprehensive analysis of the road's impact on the area's biodiversity.
