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.
Independence Day (Philippines)
The United States of America granted independence to the Philippines on July 4, 1946 through the Treaty of Manila. July 4 was chosen as the date by the United States because it corresponds to the United States' Independence Day, and that day was observed in the Philippines as "Independence Day" until 1962. On May 12, 1962, President Diosdado Macapagal issued Presidential Proclamation No. 28, which declared June 12 a special public holiday throughout the Philippines, "... in commemoration of our people's declaration of their inherent and inalienable right to freedom and independence." On August 4, 1964, Republic Act No. 4166 renamed July 4 holiday as "Philippine Republic Day", proclaimed June 12 as "Philippine Independence Day", and enjoined all citizens of the Philippines to observe the latter with befitting rites.
