much of Burma laid waste by the fighting. Overall, the Japanese lost some 150,000 men in Burma. Only 1,700 prisoners were taken.
Although many Burmese fought initially for the Japanese, some Burmese, mostly from the ethnic minorities, also served in the British Burma Army. The Burma National Army and the Arakan National Army fought with the Japanese from 1942 to 1944, but switched allegiance to the Allied side in 1945.
Following World War II, Aung San negotiated the Panglong Agreement with ethnic leaders that guaranteed the independence of Burma as a unified state. In 1947, Aung San became Deputy Chairman of the Executive Council of Burma, a transitional government. But in July 1947, political rivals assassinated Aung San and several cabinet members.
Independence
On 4 January 1948, the nation became an independent republic, named the Union of Burma, with Sao Shwe Thaik as its first President and U Nu as its first Prime Minister. Unlike most other former British colonies and overseas territories, it did not become a member of the Commonwealth. A bicameral parliament was formed, consisting of a Chamber of Deputies and a Chamber of Nationalities, and multi-party elections were held in 1951–1952, 1956 and 1960.
The geographical area Burma encompasses today can be traced to the Panglong Agreement, which combined Burma Proper, which consisted of Lower Burma and Upper Burma, and the Frontier Areas, which had been administered separately by the British.
In 1961, U Thant, then the Union of Burma's Permanent Representative to the United Nations and former Secretary to the Prime Minister, was elected Secretary-General of the United Nations, a position he held for ten years. Among the Burmese to work at the UN when he was Secretary-General was a young Aung San Suu Kyi, who went on to become winner of the 1991 Nobel Peace Prize.
On 2 March 1962, the military led by General Ne Win took control of Burma through a coup
