San Isidro, officially the Municipality of San Isidro (Ilocano: Ili ti San Isidro; Tagalog: Bayan ng San Isidro), is a 5th class municipality in the provinceofIsabela, Philippines. According to the 2020 census, it has a population of 27,044 people.[4]
History records that the early inhabitants of San Isidro were the Yogads, the natives of Echague. However, Ilokanos later settled in Camarag, making the Yogad-Ilokano groups the dominant population in the town. The Ilokanos came from Ilocos Sur and Ilocos Norte, persuaded by Antonio Mangadap, a well-traveled leader who journeyed through Northern Luzon. Mangadap’s son, Jordan, who became the leader of Camarag, served as gobernadorcillo and judge. Other members of the Mangadap clan also held leadership positions in Camarag, including Alfredo, the father of Mayor Proceso Mangadap.[6]
In the 18th century, when names such as Echague and San Isidro were not yet known, Camarag was already a popular place. The name Camarag was derived from the Camarag trees abundant in the area during the Spanish period in 1710. A significant Roman Catholic Church and a road connecting Camarag to other places like Santiago and Nueva Vizcaya were constructed, and the ruins of these landmarks still exist today. In 1776, Camarag became a town of the Province of Cagayan, the lone province in the Cagayan Valley at that time. However, in 1839, Camarag became the capital of Nueva Vizcaya when the province was created. Seventeen years later, in 1856, it became a town of Isabela, along with others such as Cabagan, Tumauini, Ilagan, Gamu, Angadanan, Carig (present-day Santiago), Palanan, Alamo, Gaddang, Mayoyao, Brengiones, and Catalaganes.[6]
Camarag remained a town for many years until the town site was transferred to Katuray, a location near the Cagayan River and the present site of Echague. The transfer occurred in 1863, and Katuray was renamed Echague in honor of General Rafael de Echague, the then-governor general of the country. The move was motivated by Katuray's proximity to the Cagayan River, the main transport artery, and the commercial center in the Cagayan Valley. Additionally, Katuray was surrounded by barangays producing high-quality tobacco and had fertile soil ideal for agriculture. With the town site transfer to Katuray in 1863, Camarag became a barrio of Echague. This remained the case until 1967 when San Isidro was established as a separate municipality, 104 years later. Thus, Camarag can be seen as the "mother" of Echague, which in turn became the "mother" of San Isidro.[6]
The opening of the San Jose-Santa Fee road in the 1920s facilitated the movement of people from Ilocos and Central Luzon to the Cagayan Valley, with many settling in Camarag. Leaders among these new settlers included Benito Tumamao, Vicente Ramos, Ramon Felipe, Tomas Galapia, and Alejandro Viloria. The influx of people into Camarag led to a population increase, which in turn boosted trade and commerce.[6]
On June 17, 1967, Republic Act 5139, authored by Representative Melanio T. Singson, became law, creating the municipality of San Isidro. This law separated San Isidro from the municipality of Echague, its "mother town" since 1863. The town was officially inaugurated on January 1, 1968. The initiative to create San Isidro began in 1966 when Barangay Captain Guillermo Mariano and Municipal Councilor Ricardo Netro, both residents of San Isidro along with former Echague Mayor Patricio Ramos, then a Board Member of Isabela, petitioned Representative Singson to introduce a bill in the Philippine Congress to establish the new town of San Isidro.[6]
Singson initially opposed the creation of a new town due to the challenges of managing a new municipality, logistical constraints, and the limited area of the proposed municipality. However, he eventually relented to the group's persistence and enthusiasm and filed the bill in Congress. It was expected that the town site would be in Camarag due to its historical importance and popularity. However, since Camarag was located on the boundary of Echague, the site was conveniently assigned to its current location, between Barangay Gomez and Barangay Rizal.[6]
Since its establishment in 1967, the municipality of San Isidro has seen ten political administrations. Notably, Jolly P. Silverio stands out as one of the most influential leaders who spurred development in the area. Currently, the municipality is under the leadership of a young and dynamic mayor celebrated for his significant achievements.[6]
Today, while the Ilokanos remain the dominant group in San Isidro, the municipality is home to a diverse population. Tagalogs, Pangasinense, Ibanags, Gaddangs, and others have made San Isidro their place of residence and commerce.[6]
San Isidro is politically subdivided into 13 barangays. [7] Each barangay consists of puroks while some have sitios.
