The Hare-Hawes Cutting Act, passed by Congress in 1932, provided for complete independence of the islands in 1945 after 10 years of self-government under U.S. supervision. The bill had been drawn up with the aid of a commission from the Philippines, but Manuel L. Quezon, the leader of the dominant Nationalist party, opposed it, partially because of its threat of American tariffs against Philippine products but principally because of the provisions leaving naval bases in U.S. hands. Under his influence, the Philippine legislature rejected the bill. The Tydings-McDuffie Independence Act (1934) closely resembled the Hare-Hawes Cutting Act, but struck the provisions for American bases and carried a promise of further study to correct “imperfections or inequalities.”

The Philippine legislature ratified the bill; a constitution, approved by President Roosevelt (Mar., 1935) was accepted by the Philippine people in a plebiscite (May); and Quezon was elected the first president (Sept.). When Quezon was inaugurated on Nov. 15, 1935, the Commonwealth of the Philippines was formally established. Quezon was reelected in Nov., 1941. To develop defensive forces against possible aggression, Gen. Douglas MacArthur was brought to the islands as military adviser in 1935, and the following year he became field marshal of the Commonwealth army.
