Commonwealth of the Philippines (1935–1946)

Government and institutions

The Commonwealth operated under a constitution that established an executive president, a judiciary led by a Supreme Court, and a legislature. Manuel L. Quezon was elected the first president in 1935 and led efforts to build civil institutions, a national bureaucracy, and public services. Initially the lawmaking body was a single National Assembly, dominated by the Nacionalista Party; constitutional amendments and political developments later restored a bicameral Congress with a Senate and House of Representatives.

Key policies and social changes

During the Commonwealth period the government pursued policies to strengthen administration, promote economic development, and define national identity. In 1937 a national language commission selected Tagalog as the basis for a national language, a decision promoted by leaders based in Manila. The Commonwealth also expanded political participation: women gained the right to vote after a 1937 plebiscite. The economy remained largely agricultural, but planners emphasized infrastructure, education, and public health to modernize society.

War, occupation, and restoration

The planned transition to independence was disrupted by World War II. Japanese forces occupied the islands from 1942 to 1945; the Commonwealth government evacuated and operated in exile for part of the war. During the occupation a Japanese-sponsored regime was installed, while Filipino and American forces, together with guerrilla movements, resisted. After liberation by Allied forces the Commonwealth government was restored on the islands and resumed preparations for sovereignty.

End of the Commonwealth and legacy

The Commonwealth formally ended when full independence was granted in 1946, marking the start of the Third Republic of the Philippines. The Commonwealth era is remembered for its role in institution building, debates over language and national identity, and efforts to prepare public administration and the economy for self-rule. It also remains significant for how the interruption of war reshaped the political transition and postwar reconstruction.

Notable facts

• The Commonwealth was established by U.S. legislation to provide a defined path toward independence.
• Its presidency combined strong executive powers with a constitutional judiciary.
• Wartime occupation created competing claims to authority and delayed independence until 1946.
