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.
Philippine Declaration of Independence
Sometime in the 1980s or 1990s the Declaration was stolen from the National Library. As part of a larger investigation into the widespread theft of historical documents and a subsequent public appeal for the return of stolen documents, the Declaration was returned to the National Library in 1994 by historian and University of the Philippines professor Milagros Guerrero, who mediated the return of the documents.
