Answer:
Founded on January 19, 1946 by Senate President Manuel Roxas, Senate President Pro-Tempore Elpidio Quirino, and former 9th Senatorial District Senator José Avelino from the breakaway liberal wing of the old Nacionalista Party, the Liberal Party remains the second-oldest active political party in the Philippines after the Nacionalistas, and the oldest continually-active party. The Liberals served as the governing party of four Philippine presidents: Manuel Roxas, Elpidio Quirino, Diosdado Macapagal, and Benigno Aquino III. As a vocal opposition party against the regime of Ferdinand Marcos, the party reemerged as a major political party after Marcos's overthrow in the People Power Revolution and the establishment of the Fifth Republic. It subsequently served as a senior member of President Corazón Aquino's UNIDO coalition. Upon Corazón Aquino's death in 2009, the party regained popularity, winning the 2010 Philippine presidential election under Benigno Aquino III. The Liberal Party returned to government, serving from 2010 to 2016. The party lost control of the presidency to Rodrigo Duterte of PDP–Laban in the 2016 presidential election and became the leading opposition party; however its vice presidential candidate Leni Robredo won, narrowly beating Nacionalista candidate Ferdinand Marcos, Jr.
