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.
Manuel Roxas
On August 5, 1946, the Congress of the Philippines ratified the Treaty of General Relations that had been entered into by and between the Republic of the Philippines and the United States on July 4, 1946. Aside from withdrawing her sovereignty from the Philippines and recognizing her independence, the Treaty reserved for the United States some bases for the mutual protection of both countries; consented that the United States represent the Philippines in countries where the latter had not yet established diplomatic representation; made the Philippines assume all debts and obligations of the former government in the Philippines; and provided for the settlement of property rights of the citizens of both countries.
