politician who in 1937 became the first Burmese premier under British rule; he later was head of state in the pro-Japanese government during World War II (August 1943–May 1945).

Ba Maw was educated at Rangoon College, Calcutta University, the University of Cambridge, and the University of Bordeaux, Fr., where he received a doctorate in 1924. Admitted to the English bar the same year, he first came into prominence as defense lawyer for the Burmese rebel leader Saya San in 1931.

During the early 1930s Ba Maw became a prominent opponent of Britain's plan to remove Burma (Myanmar) from the jurisdiction of the Indian viceroy, since he believed that a separate Burma would receive a much smaller measure of self-rule than India as a result. In 1934, however, he reversed his position, agreeing to support the pro-separationists in a coalition government. That year he was made minister of education for Burma. When the new constitution, providing for separation of Burma from India, went into effect on April 1, 1937, he became the first premier, and he held office until he was defeated by a coalition in February 1939.

After his defeat, Ba Maw allied with other Burmese leaders to form the Freedom Bloc, which opposed Burma's participation with the Allies in World War II. In August 1940 he was arrested by the British for sedition and remained in prison until the Japanese invasion in 1942. During the Japanese occupation (1943–45), he was adipati (head of state) of a theoretically independent Burma, although the country was actually a Japanese satellite. He fled to Japan when the Allies reentered Burma. After a brief time in an Allied prison, he returned and unsuccessfully attempted to reenter politics. He later retired to private life.
