Corazon Aquino was married to Senator Benigno Aquino Jr., who was one of the most prominent critics of President Marcos. After the assassination of her husband on 21 August 1983, she emerged as leader of the opposition against the president. In late 1985, Marcos called for a snap election, and Aquino ran for president with former Senator Salvador Laurel as her running mate for vice president. After the election held on 7 February 1986, the Batasang Pambansa proclaimed Marcos and his running mate Arturo Tolentino as the winners, which prompted allegations of electoral fraud and Aquino's call for massive civil disobedience actions. Subsequently, the People Power Revolution, a non-violent mass demonstration movement, took place from 22 February to 25 February. The People Power Revolution, along with defections from the Armed Forces of the Philippines and support from the Philippine Catholic Church, successfully ousted Marcos and secured Aquino's accession to the presidency on 25 February 1986. Prior to her election as president, Aquino had not held any elected office. Corazon Aquino was the first female president of the Philippines.
