Benigno Simeon "Ninoy" Aquino, Jr. (November 27, 1932 – August 21, 1983) was a Filipino Senator (1967–1972) and a former Governor of Tarlac. Aquino, together with Gerry Roxas and Jovito Salonga, formed the leadership of the opposition to the government of PresidentFerdinand Marcos. Shortly after the imposition of martial law, he was arrested in 1972 along with other dissidents and incarcerated for seven years. In 1980 Aquino was permitted to travel to the United States for medical treatment following a heart attack. He was assassinated at the Manila International Airport in 1983 upon returning from his self-imposed exile. His death catapulted his widow, Corazon Aquino, into the political limelight, and prompted her to run for president as member of the UNIDO party in the 1986 snap elections.
