1. Historical Background of the Region
Western Visayas covers the provinces of Aklan, Antique, Capiz, Guimaras, Iloilo and Negros Occidental. Except for Aklan and Guimaras, the four (4) provinces were created by virtue of Republic Act No. 2711 on March 10, 1917. The province of Aklan was created on April 25, 1956 under Republic Act No. 1414 and Guimaras as a sub-province of Iloilo since 1966 became a province after the referendum on May 11, 1992.
Aklan is associated with a Datu Bendahara Kalantiaw who is believed to be the country’s first lawgiver. The name of the province is also linked with the famous Ati-Atihan Festival held in the provincial capital of Kalibo. This festival commemorates a peace pact held in the 13th century between the aborigines and the early Malay immigrants.
Antique was considered as the “Home of the Sacadas” because it was a major source of migrant labor for the sugar cane fields of Negros Occidental. Its name was derived from the word “Hamtic” after “hantic-hantic” meaning large ants that are abundant in the place.
The province of Capiz derived its name from the Visayan word “Kapid” meaning twins, which were born in the area.
Guimaras was formerly called Himal-us from the word "paghimud-us", meaning a struggle for survival. In the early part of the Spanish regime, the name Himal-us was changed to Guimaras.
Iloilo was formerly called “Irong-irong” under Datu Paiburong in the confederation of Madiaas, first known organization of the barangays.
The province of Negros Occidental used to be called “Buglas” but the Spaniards changed it to Negros due to the predominant presence of Negritoes.
