The Commonwealth of the Philippines was the transitional government that ruled the Philippines from 1935 to 1946, replacing the Insular Government and establishing self-governance. Manuel L. Quezon was elected as the first Filipino president of the Commonwealth. During his term, he tackled issues like land reform, promoting development, and opposing corruption. The Commonwealth established critical institutions and laid the groundwork for an independent nation by enacting laws through the National Assembly and establishing a presidential system of government. It granted more privileges to Filipinos and aimed to achieve full independence from the United States.
