The alliance was formed in July 1932 by parties that were not in favour of Burma being separated from British Raj in order to contest the 1932 general elections,[1] as the British government had indicated that it would take the outcome of the elections as an indication of Burmese opinion.
The alliance was also backed by Buddhist monks,[1] who the Separation League sought to ban from political involvement.
[2] The League soon split into two groups; the Chit Hlaing faction led by Chit Hlaing, U Myat Tha Dun and U Paw Tun and the Ba Maw faction led by Ba Maw, Kyaw Myint and Ramree U Maung Maung.
[1] In the elections the League won 42 seats, defeating the Separationists.
However, when the Legislative Council met, the alliance refused to support a motion calling for Burma to remain part of India.
