Ilocos Sur History...  |  | Before the advent of the Spanish Regime, settlements already existed along the coves or “looc” in the northern part of Luzon. These settlements called the “Ylocos” which extended from Bangui in the north to Namacpacan in the south were discovered during the expedition led by Juan de Salcedo in 1572.
Juan de Salcedo decided to establish his headquarters in a settlement along the Mestizo River, then named “Kabigaan” because of the “gabi”-like plants abundantly growing by the bank of the river. Vigan also became the seat of the Archdiocese of Nueva Segovia and was called “Ciudad Fernandina” in honor of King Ferdinand. Vigan remains to be the capital town of Ilocos Sur.
On February 2, 1818, the Ylocos was divided into two provinces: Ilocos Sur and Ilocos Norte. At that time, Ilocos Sur encompassed what are now the northern towns of La Union up to Luna and Abra. Also annexed were Lepanto and Amburayan in Mt. Province. Act 2683 passed on March 1917 by the Philippine Legislature defined the present geographical boundaries of Ilocos Sur. |
