# Iloilo

Iloilo (/ˌɪloʊˈiːloʊ/ ih-loh-EE-loh;), also called Iloilo Province, officially the Province of Iloilo (Hiligaynon: Kapuoran sang Iloilo; Kinaray-a: Kapuoran kang Iloilo; Tagalog: Lalawigan ng Iloilo; Spanish: Provincia de Iloílo), is a province in the Philippines located in the Western Visayas region. Its capital and largest city is Iloilo City, the regional center of Western Visayas and politically independent from the province. Iloilo occupies the southeast portion of the Visayan island of Panay and is bordered by the province of Antique to the west, Capiz to the north, the Jintotolo Channel to the northeast, the Guimaras Strait to the east, and the Iloilo Strait and Panay Gulf to the southwest. Iloilo City, its capital, is the center of the Iloilo–Guimaras metropolitan area or Metro Iloilo–Guimaras, and is geographically located in the province and grouped under it by the Philippine Statistics Authority, but remains politically independent from the provincial government. According to the 2020 census, the population of the province (excluding Iloilo City) is 2,051,899. If Iloilo City is included, the population is 2,509,525 in total.
Iloilo is known for its rich history and cultural heritage. The southern part of the province is home to many Spanish-era historic sites, including the Miag-ao Church, a UNESCO World Heritage Site in the Philippines. It also boasts several other prominent structures, such as the San Joaquin Campo Santo, San Joaquin Church, and Santa Barbara Church, all recognized as National Cultural Treasures by the National Museum of the Philippines. In the northern part, it is known for beaches and islands, including the Bantigue Sandbar, Tangke Lagoon, Cabugao Island, and Antonia Island, all part of the Islas de Gigantes. Additionally, Sicogon Island, situated south of the group of islands, has gained popularity as a luxury tourist destination.

## Etymology

The name of the province is derived from Iloilo City, which in turn is derived from the older name "Irong-irong" (Philippine Spanish: Irong̃-írong̃) meaning "nose-like", referring to the promontory between two rivers (Iloilo and Batiano) where the Fort San Pedro and the 17th-century Spanish port were located.

## History
### Early history

No pre-Hispanic written accounts of Iloilo and Panay island exist today. Oral tradition, in the form of recited epics like the Hinilawod, has survived to a small degree. A few recordings of these epic poems exist. The most notable are the works of noted Filipino Anthropologist Felipe Jocano.
While no current archaeological evidence exist describing pre-Hispanic Iloilo, an original work by Pedro Alcantara Monteclaro published in 1907 called Maragtas details the alleged accounts of the founding of the various pre-Hispanic polities on Panay Island. The book is based on oral and written accounts available to the author at the time. The author made no claim on the historical accuracy of the accounts.
According to Maragtas, Madja-as was founded after ten datus fled Borneo and landed on Panay Island. The book then goes on to detail their subsequent purchase of the coastal lands in which they settled from the native Ati people.
Datu Paiburong, one of the ten fleeing datus, established a settlement and named it Irong-Irong after an islet of the same name on the Batiano River. Afterwards, the warriors Labaodungon and Paybare, upon advice of datu Paiboring then recruited local fighters from the Philippines and fellow immigrants from Borneo and they returned to Borneo at Odtojan where the enemy of the ten datus, Makatunaw, ruled, Rajah or Sultan Makatunao, and they killed him and sacked the city he ruled and returned to the newly founded towns of the ten datus.

### Spanish colonial era

Spain eventually succeeded on conquering of the island of Panay when Spanish conquistador Miguel López de Legazpi moved his headquarters from the island of Cebu and creating the first Spanish settlement in the island in Ogtong in 1566. This is mainly due in part to the rivalries between the Bisaya and the Moro, of which the former found an ally in Spanish against the latter. The Bisayas accepted alliances with Spain, to defend themselves against the enslaving Moros. To this end, Iloilo contributed troops in the Castille War against the Sultanate of Brunei.
In 1581, the encomienda in Ogtong was moved to La Villa Rica de Arevalo, because of frequent coastal raids by the Dutch privateers. Furthermore, an attack in the year 1600 (Part of the Spanish–Moro conflict) where there was a large Muslim armada to destroy Iloilo City, led by two Moros named Sirungan and Salikala who lead the Muslim force of 70 ships and 4,000 warriors that had raided and attacked several Visayan islands in order to abduct slaves to sell to their allies in the Sultanate of Demak and the Sultanate of Malacca, eventually caused the move of the city center further on to the mouth of the Irong-Irong river founding what is now Iloilo City and constructing Fort San Pedro to defend it in 1616.
Nevertheless, when the 4,000 Moros led by Sirungan and Salikala tried to attack Iloilo City they were repulsed with heavy losses in the town of Arevalo by a force of 1,000 Hiligaynon warriors and 70 Mexican arquebusiers under the command of Juan García de Sierra, the Spanish officer who died in the battle. The Spanish Christianized the area.
Soon, the area itself began to prosper, due to its successful textile and sugar industry. As a result, it received Chinese immigrants from the west (that worked for its trades) and Latinos from the ports of Mexico in the east (to man its military installations). The Jesuits soon built a school for Spanish and Visayan boys in Tigbauan, Iloilo. Later in the 1700s, Iloilo was home to 166 Spanish Filipino families and 29,723 native families.$^{:113}$

### American colonial era

During the American colonial period, Iloilo became a home to many firsts: including the first department stores and cinema theaters in the Commonwealth of the Philippines.

### Japanese occupation

Iloilo experienced severe devastation during the events of World War II. The Japanese built "comfort stations" in Iloilo in 1942, where they imprisoned Filipino "comfort women" who they routinely gang-raped, brutalized, and murdered for entertainment. Nevertheless, during the Japanese occupation, Macario Peralta Jr., freed most of Panay (with little exceptions) from Japanese Imperialism, thus other allied guerillas in other provinces from Romblon, Palawan, Marinduque and portions of Masbate and Mindoro, considered majority liberated Panay Island, the "Primus inter pares" in their alliance network.$^{:110}$

### Philippine independence

Iloilo became a province of the newly fledged Republic of the Philippines when the archipelago gained independence from the United States on July 4, 1946.

## Geography

The province covers a total area of 5,000.83 square kilometres (1,930.83 sq mi) occupying the central and eastern section of Panay island in the Western Visayas region. If Iloilo City is included for geographical purposes, Iloilo has an area of 5,079.17 square kilometres (1,961.08 sq mi). The province is bordered by the province of Antique to the west, Capiz to the north, the Jintotolo Channel to the northeast, the Visayan Sea and Guimaras Strait to the east, and the Iloilo Strait and Panay Gulf to the southwest.
The province is divided into two distinct geographic regions; the highlands of the Central Panay Mountain Range on the western border and the lowland plains which account for a larger portion of the province. Small islands east of its northernmost tip also dot the Visayan Sea - of these, Pan de Azucar and Sicogon are well-known. Mount Baloy is the highest mountain in Iloilo with an elevation of 6,424 feet (1,958 m) above sea level, located on the triple border of Iloilo, Capiz, and Antique. Other peaks are Mount Llorente 4,409 ft. (1,344m), Mount Sansanan 4,219 ft. (1,286m), Mount Napulak 4,095 ft. (1,248 m), Mount Balabag 3,728 ft. (1,136m).
Expansive fishponds and mangrove wetlands are found along the coasts and rivers of Iloilo City and the towns of Oton, Leganes, Zarraga, Dumangas, Anilao, Banate, Barotac Viejo, Barotac Nuevo, Ajuy, Balasan and Carles.

Iloilo is one of the most competitive provinces in the Philippines, recognized for its strong economy, resilience, and effective governance. This collaboration has resulted in an economic boom that has generated thousands of jobs and propelled the province to become one of the richest in the country.
Its capital, Iloilo City, is one of the largest cities in the country in terms of economic activity. It serves as the economic center of the province and supports a wide range of industries and services, including real estate, accommodation, healthcare, education, retail, business, and IT/BPO sectors. It also functions as a key port for domestic and international trade. The city's diverse economy significantly contributes to the overall development of the province.
Metro Iloilo, which includes the neighboring municipalities of Pavia, Oton, Leganes, and Santa Barbara, also plays a significant role in the province's economy. Pavia is known as an agricultural-industrial center, combining farming with industrial developments, and is also recognized for its commercial centers and residential developments. Oton contributes with its agricultural production and emerging retail sector, and will soon host the largest central business district (CBD) in Iloilo. Leganes is notable for its light industries and hosts the province's first agro-industrial economic zone, contributing to both agriculture and light manufacturing. Santa Barbara is known for its historical sites and a growing tourism industry.
The northern part of Iloilo is notable for its robust fishing industry and expanding tourism sector, benefiting from its proximity to the Visayan Sea and natural attractions like beaches and marine reserves. The central part of the province functions as an agri-industrial hub, producing a variety of agricultural products such as corn, rice, bananas, pineapples, and sugar. The highland areas, including Bucari in Leon and Alimodian, are known for high-value crops like strawberries and mangoes, and offer tourism opportunities through inland resorts and trekking sites.
The sugar industry is a key economic driver in Passi City and nearby towns like Lambunao, Dueñas, San Enrique, and Bingawan. In southern Iloilo, the economy is largely driven by tourism, with historical sites, colonial architecture, and coastal attractions in towns such as Tigbauan, Guimbal, Miagao, and San Joaquin playing a significant role in the local economy.

## Government

The government of Iloilo was established in 1566 when the Spanish settled a colonial center in Ogtong (now Oton). Control was later shifted to La Villa Rica de Arevalo (now Arevalo, Iloilo City) in 1581, which also served as the seat of the Spanish Government overseeing vast territories encompassing Iloilo, Capiz, Aklan, Antique, and surrounding islands such as Negros, Guimaras, Cuyo, Palawan, Caluya, Romblon, and Boracay. Over time, these territories gained independence. By 1616, the seat of government was transferred to La Punta, now known as Iloilo City Proper. This relocation marked a significant increase in colonial power, and the city's economy boomed, making it the largest in the Philippines after Manila during the Spanish period until the American period.
The Governor of Iloilo serves as the local chief executive of the province, with the official office located at the Iloilo Provincial Capitol. Historically, the governor, along with the alcalde-mayor and presidente municipal, held office at the Casa Real de Iloilo from 1869 until 2006, when the larger capitol building adjacent to it was completed.
