Sergio Osmena served as the president of the Philippines in the 1940s and founded the Nationalist Party. Prior to his political career, Osmena worked as a newspaper reporter and received a degree in law from the University of Santo Tomas in Manila.
Osmena founded the Nationalist Party in 1907, when he was first delegated as a member of the Philippine National Assembly. Throughout his political career, he held a number of different roles, including speaker of the House of Representatives and Senate. While he worked in Senate, he traveled to Washington, D.C., to help pass the independence bill. It wasn't until 1934 that the Philippines became its own independent state, an initiative that was begun by Osmena.
