History of Guimaras Island

of Nayup and Igang as subordinate to Oton, Iloilo. Gómez Pérez Dasmariñas, the 7th Spanish Governor-General, noted in a 20 June 1591 report to King Philip II that the friars of Oton made regular visits to the island.

In 1742, the island came under the jurisdiction of Dumangas – now known as Iloilo, until 1751 when the Augustinian Order was replaced by the Jesuits, after which the Dominican order took over Guimaras. The Jesuits, who had established a school in Iloilo and had missions in Molo and Arevalo, charge of the island. By 1755, it was organized into a regular parish. When the population increased considerably, the island was given its municipal status with a seat of government at Tilad (today Buenavista).

American Era and the Second World War

Under American rule, the Guimarasnons were given the opportunity to elect their municipal president in 1908.

Douglas MacArthur, a fresh graduate from West Point as a Second Lieutenant at the age of 23, came to Iloilo as the head of the company of U.S. Army Corps of Engineers. They constructed roads and the Sto. Rosario Wharf, presently named MacArthur's Wharf, which are still in use today. In November 1903, while working on Guimaras, he was ambushed by a pair of Filipino brigands or guerrillas; he shot and killed both with his pistol.

In 1942, Japanese Imperial forces landed on Guimaras Island as the Empire of Japan began its occupation of the country during the Second World War.

In 1945, the combined United States and Philippine Commonwealth forces landed on Guimaras Island, attacking the Japanese and defeating them in the Battle of Guimaras, which led to the liberation of the island.
