[4] Encompassing the entirety of Simara Island, the municipality is named after the Spanish governor-general Sebastián Hurtado de Corcuera who ruled the Philippines from 1635 to 1644 on behalf of King Philip IV of Spain.He also ordered the construction of a watchtower in Tacasan, which would serve as a lookout and warning for the locals of impending Muslim raids that plagued the province at that time.On March 12, elements from Companies B and C of the 19th Infantry, 24th Division of the US 8th Army landed in Simara led by 1st Lt. David B. Bernard.[8] After four days of mortar and naval bombardment and heavy fighting, the Americans were able to subdue the Japanese in Tanro-aw and liberate the island.It is a hilly, volcanic island with many hot springs, while stretches of flat land lie along its northern coast.The island's inhabitants are predominantly Roman Catholic, with a small number of Protestants, Iglesia ni Cristo, and Jehovah's Witnesses.Pursuant to Chapter II, Title II, Book III of Republic Act 7160 or the Local Government Code of 1991,[22] the municipal government is composed of a mayor (alkalde), a vice mayor (bise alkalde) and members (kagawad) of the legislative branch Sangguniang Bayan alongside a secretary to the said legislature, all of which are elected to a three-year term and are eligible to run for three consecutive terms.This is also the typical time for Asi families living in Metro Manila or abroad to visit the island since it coincides with the Lenten season and barangay fiestas.
