Philippine Declaration of Independence
Following the end of World War II, the United States granted independence to the Philippines on 4 July 1946 via the Treaty of Manila. July 4 was observed in the Philippines as "Independence Day" until August 4, 1964 when, upon the advice of historians and the urging of nationalists, President Diosdado Macapagal signed into law Republic Act No. 4166 designating June 12 as the country's "Independence Day". June 12 had previously been observed as "Flag Day" and many government buildings are urged to display the Philippine Flag in their offices.
History of the Philippines (1898–1946)
Following the passage of the Philippine Independence Act in 1934, a Philippine presidential election was held in 1935. Manuel L. Quezon was elected and inaugurated second President of the Philippines on November 15, 1935. The Insular Government was dissolved and the Commonwealth of the Philippines was brought into existence. The Commonwealth of the Philippines was intended to be a transitional government in preparation for the country's full achievement of independence in 1946.
