Oton, officially the Municipality of Oton ([oˈton]; Kinaray-a: Banwa kang Oton, Hiligaynon: Banwa sang Oton, Tagalog: Bayan ng Oton), is a municipality in the province of Iloilo, Philippines. According to the 2024 census, it has a population of 99,920 people making it as the most populous town in the province and the entire Panay island. Oton is 11 kilometres (6.8 mi) west of Iloilo City and is part of the Metro Iloilo–Guimaras area.

Key Information

Oton is the second oldest Spanish settlement in the Philippines after Cebu. It was founded in 1571 and later became the capital of the islands of Panay, Guimaras, Negros, Tablas, Sibuyan, and Romblon.[5]

History

[edit]

Oton, formerly known as Ogtong, has a rich history dating back to the settlement of Malays in the area. Evidence of this early settlement includes the discovery of a gold death mask in Barangay San Antonio during the 1960s. The town's name, Oton, was mentioned in records from the Yuan Dynasty in the 1300s, referred to as in Hokkien Chinese: 啞陳; Pe̍h-ōe-jī: A-tân.[6]

The arrival of the Spanish in the mid-16th century marked a significant turning point in Oton's history. The Spanish designated Oton as the capital of Alcaldia de Oton (now the province of Iloilo) which covered the islands of Panay, Guimaras, Negros, Tablas, Sibuyan, and Romblon.[7][8] Spanish missionaries used Oton as a base to spread Catholicism to neighboring settlements, including Jaro, Iloilo, Tigbauan, Cordova, Alimodian, Igbaras, Tubungan, Camando, Damilisan, and Tiolas.

Oton played a vital role in the Manila galleon trade, as new agricultural products from the trade route arrived in the town. Many ships traveling from Cebu would dock in Oton before continuing on to Manila. However, Oton's location made it vulnerable to pirate attacks, prompting the Spanish colonial authorities to relocate the capital a few kilometers away to La Punta, which is now known as Iloilo City Proper, in the 1600s. This move was intended to enhance the town's defense against pirate raids.[9]

In the 21st century, Oton has transitioned from an agricultural town to a growing commercial center, with significant investments, including those by Vista Land.[10]

History

Pre-Colonial and Early Settlement

The area encompassing modern Oton was part of Island, inhabited in pre-colonial times primarily by the Ati, indigenous peoples characterized as small, dark-skinned hunter-gatherers who were the earliest known residents of the region. Subsequent waves of Austronesian migrants, often described as Malay settlers, arrived and established communities focused on maritime trade and craftsmanship. By the early , Oton hosted a thriving Malay settlement with a key port—now near the Batiano Bridge site—that served as one of five ancient trading harbors in the , facilitating commerce in goods like gold, beeswax, and woven textiles; local inhabitants were renowned for expertise, constructing large vessels in dedicated yards. Archaeological excavations in Oton and nearby sites have uncovered artifacts indicating human activity predating the legendary migration narrative (circa 1250 CE, involving ten datus from ), suggesting continuous occupation by proto-Ilonggo or related Visayan groups with advanced weaving and maritime traditions, though these findings challenge romanticized oral histories by pointing to deeper indigenous roots rather than external origins. European early settlement commenced in 1566, when Spanish explorer Miguel López de Legazpi's expedition, seeking refuge and resources after , established the first colonial outpost in at Ogtong (Oton's pre-Hispanic name), marking it as the second permanent Spanish settlement in the archipelago after and initially serving as the administrative seat for the region from 1572 to 1581. This foothold involved alliances with local datus, conversion efforts starting with Fray Martín de Rada's arrival in 1569, and the construction of early fortifications amid resistance from some leaders, transitioning the area from autonomous trading hubs to a node in Spain's galleon trade network.

Spanish Colonial Period

The Spanish colonial presence in Oton, then known as Ogtong, began in 1566 when forces under arrived in Island and established the area's first settlement there, marking it as the initial Spanish foothold on the island and the second such colonial center in the after . In 1569, Ogtong served as a strategic hiding place for Legazpi's armada, and Don Miguel de Loarca was appointed encomendero over the region. This early settlement facilitated the integration of local Visayan communities into the colonial framework, with the site leveraging its coastal position for initial administrative and logistical purposes. Oton was formally organized as a pueblo on May 3, 1572, by Franciscan friar Martín de Rada, becoming the third such pueblo in the following and ; de Rada also constructed the first church there in 1570, dedicated to Our Lady of the Immaculate Conception, which hosted the inaugural church council in the archipelago addressing issues. The name "Oton" is a Hispanized form of the Hiligaynon phrase "ogtong adlaw" (meaning midday or noon), stemming from a native's response to Spanish inquiries about the time or place name, which explorers mispronounced due to difficulties with local phonetics. These developments underscored Oton's role in early evangelization efforts, as Franciscan missionaries began preaching there shortly after establishing a convent in in 1565. Administratively, Oton functioned as the capital of the Alcaldia de Oton (later referred to as Alcaldia de ) starting in 1572, overseeing a vast jurisdiction that included , , parts of , Tablas, Sibuyan, and until the seat shifted to Arevalo in 1581. This period saw the imposition of systems and boundary delineations by Spanish councilors, integrating local datu-led structures into colonial while encountering resistance, such as the 1603 establishment of an alternative church by local leader Tapar blending indigenous and Christian elements. By the late , Oton's prominence waned as nearby settlements like (formerly Irong-Irong) emerged, with the latter becoming a fortified port around 1700 for better defense against Moro raids. Economically, Oton served as an early hub for , where local —renowned as master craftsmen—combined indigenous techniques with Spanish designs to construct Manila galleons, though this activity later migrated to other regions like Bicol and . The area also functioned as a Chinese , evidenced by artifacts such as a 14th-15th century gold death mask unearthed in San , highlighting pre- and early colonial commercial ties. Local women contributed through fine textiles on household looms, supporting both subsistence and within the colonial .

Post-Colonial Developments

Following the Spanish-American War, American forces assumed control of Oton in February 1900, marking the transition to U.S. colonial administration in the region. During this period, infrastructure and education saw initial advancements; the Oton Public Market was constructed in the 1930s, reflecting continued development of central town facilities originally patterned after Spanish-era designs. Oton Central Elementary School was established between 1911 and 1913, with American Thomasite teachers enhancing local education systems. Under Municipal President Epifanio Tiapon, efforts included further school construction, concreting of the public market, and road improvements linking Oton to . The Japanese Imperial Army invaded Panay Island on April 16, 1942, with landings near Trapiche in , initiating a period of occupation characterized by guerrilla resistance from local Filipino forces. Educational activities persisted amid wartime constraints; Oton National High School (then Oton Regional High School) conducted refresher courses from March 22 to June 1945 at the public market site. Liberation came on March 18, 1945, when U.S. 8th Army troops landed at nearby and advanced through Oton toward , where local civilians greeted the forces. Post-liberation governance fell under the Philippine Civil Affairs Unit (PACAU), facilitating the resumption of normal operations, including the high school's regular academic year from June 1945 to March 1946. After Philippine independence in 1946, Oton focused on reconstruction amid challenges like the January 25, 1948, earthquake that destroyed the Immaculate Conception Parish Church, which was not subsequently restored. The municipal building was erected in 1955 during Mayor Simplicio C. Carreon's tenure (1952–1963), supported by Senator Jose C. Zulueta, symbolizing post-war civic recovery. Economic and demographic shifts accelerated from the 1970s, with population rising from 32,862 in 1970 to 98,509 in 2020, driven by proximity to and suburban expansion. Urbanization increased to 48.2% by 2020, accompanied by commercial growth, including expanded retail areas and facilities like resorts, reflecting Oton's integration into the broader metropolitan economy. advancements, such as a 2017 power substation in Barangay and a 2020 fire station in Barangay Tagbac Sur, underscore ongoing modernization efforts.
