Masinloc became the province's first capital. However, the capital was moved among the last three towns above during its history before finally settling in Iba, due to its strategic location. Seven of the province's original northern towns, which included Bolinao, Infanta and Alaminos were later transferred under the jurisdiction of Pangasinan because of their distance from the capital. The first civil governor of Zambales during the colonial American era was Potenciano Lesaca from 1901-1903. During the dictatorship of Ferdinand Marcos, Zambales was one of the most militarized areas in the Philippines as majority of the people were against martial rule. Many opposition Sambals were detained, tortured, killed, electrocuted at the genitalia, or were listed as 'missing'. The province was one of the main supporters of the People Power Revolution in Manila, which topped the 21-year dictatorship and installed Corazon Aquino as president, bringing back democracy to the country. The province was heavily affected by the 1991 eruption of Mount Pinatubo. Due to this, the economy of the province weakened for some time, but regained vitality a few years after the government ordered the revitalization of the province and established growth in its southern towns, which later became a significant economic zone in the country by 1995.
