When British India was partitioned and the independent dominions of India and Pakistan were created in 1947, the region of Bengal was divided along religious lines. The predominantly Muslim eastern half was designated East Pakistan—and made part of the newly independent Pakistan—while the predominantly Hindu western part became the Indian state of West Bengal. Dominion status was rejected in 1956
in favor of an "Islamic republic within the Commonwealth." Attempts at civilian political rule failed, and the government imposed martial law between 1958 and 1962, and again between 1969 and 1971. Almost from the advent of independent Pakistan in 1947, frictions developed between East and West Pakistan, which were separated by more than 1,000 miles of Indian territory. East Pakistanis felt exploited by the West Pakistan-dominated central government. Linguistic, cultural, and ethnic differences also contributed to the estrangement of East from West Pakistan. Bengalis strongly resisted attempts to impose Urdu as the sole official language of Pakistan. Responding to these grievances, Sheikh Mujibur Rahman on January 4, 1948 formed a students' organization called the Chatra League.
