Commonwealth of the Philippines
After the War in the Philippines the Commonwealth was restored and a one-year transitional period in preparation for independence began. Elections followed in April 1946 with Manuel Roxas winning as the first president of the independent Republic of the Philippines and Elpidio Quirino winning as vice-president. In spite of the years of Japanese occupation, the Philippines became independent exactly as scheduled a decade before, on July 4, 1946.
History of the Philippines (1898–1946)
Philippine independence came on July 4, 1946, with the signing of the Treaty of Manila between the governments of the United States and the Philippines. The treaty provided for the recognition of the independence of the Republic of the Philippines and the relinquishment of American sovereignty over the Philippine Islands. From 1946 to 1961, Independence Day was observed on July 4. On 12 May 1962, President Macapagal issued Presidential Proclamation No. 28, proclaiming Tuesday, June 12, 1962 as a special public holiday throughout the Philippines. In 1964, Republic Act No. 4166 changed the date of Independence Day from July 4 to June 12 and renamed the July 4 holiday as Philippine Republic Day.
