Maria Corazon Sumulong Cojuangco-Aquino (January 25, 1933 – August 1, 2009) was the 11th President of the Philippines and the first woman to hold that office in Philippine history. She is best remembered for leading the 1986 People Power Revolution, which toppled Ferdinand Marcos and restored democracy in the Philippines. She is considered an icon of democracy, and was titled by TIME Magazine in 1986 as its 'Woman of the Year'.

A self-proclaimed "plain housewife", Aquino was married to Senator Benigno Aquino, Jr., the staunchest critic of then President Ferdinand Marcos. Senator Aquino was assassinated on August 21, 1983 upon returning to the Philippines after three years in exile in the United States. After her husband's assassination, Aquino emerged as the leader of the opposition against the Marcos administration. In late 1985, when President Marcos called for a snap election, Aquino ran for president with former senator Salvador Laurel as her vice-presidential running mate. After the elections were held on February 7, 1986, and the Batasang Pambansa proclaimed Marcos the winner in the elections, Aquino called for massive civil disobedience protests, declaring herself as having been cheated and as the real winner in the elections. Filipinos enthusiastically heeded her call and rallied behind her. These series of events eventually led to the ousting of Marcos and the installation of Aquino as President of the Philippines on February 25, 1986 through the People Power Revolution.
