Answer 2

The Spanish-American War began in Cuba in 1898 and soon reached the Philippines when Commodore George Dewey defeated the Spanish squadron at Manila Bay. Aguinaldo declared the independence of the Philippines on June 12, 1898, and was proclaimed head of state. As a result of its defeat in the War, Spain ceded the Philippines, together with Cuba, Guam and Puerto Rico to the United States. By 1899, the Philippine-American War ensued between the United States and the Philippine revolutionaries, which continued the violence of the previous years. The US proclaimed the war ended when Aguinaldo was captured by American troops on March 23, 1901, but the struggle continued until 1913. The country's status as a colony changed when it became the Commonwealth of the Philippines in 1935, which provided for more self-governance. Plans for increasing independence over the next decade were interrupted during World War II when Japan invaded and occupied the islands. After the Japanese were defeated in 1945, the Philippines achieved independence from the United States on July 4, 1946.
