Benigno Simeon "Ninoy" Aquino Jr., QSC (November 27, 1932 – August 21, 1983) was a Filipino politician who served as a Senator of the Philippines (1967–1972) and governor of the province of Tarlac. He was the husband of Corazon Aquino—who, after his death, eventually became President of the Philippines—and father of a later President, Benigno Aquino III. Aquino, together with Gerardo Roxas and Jovito Salonga, helped form the leadership of the opposition towards then President Ferdinand Marcos. He was the aggressive leader who together with the intellectual leader Sen. Jose W. Diokno led the overall opposition. Shortly after the imposition of martial law, Aquino was arrested in 1972 along with others associated with the New People's Army's armed insurgency and incarcerated for seven years. He founded his own party, Lakas ng Bayan and ran in the 1978 Philippine parliamentary election, but all the party's candidates lost in the election. In 1980, he was permitted by Marcos to travel to the United States for medical treatment following a heart attack. During the early 1980s he became one of the most notable critics of the Marcos regime, and enjoyed popularity across the US due to the numerous rallies he attended at the time. As the situation in the Philippines worsened, Aquino decided to return to face Marcos and restore democracy in the country, despite numerous threats against it. He was assassinated at the Manila International Airport on August 21, 1983, upon returning from his self-imposed exile. His death revitalized opposition to Marcos; it also catapulted his widow, Corazon, into the political limelight and prompted her to successfully run for a six-year term as president as a member of the United Nationalist Democratic Organization (UNIDO) party in the 1986 snap election.
