East Pakistan renames itself Bangladesh.

East Pakistan was the eastern province of Pakistan between 1956 and 1971, restructured and renamed from the province of East Bengal and covering the territory of the modern country of Bangladesh. Its land borders were with India and Burma, with a coastline on the Bay of Bengal. East Pakistanis were popularly known as "Pakistani Bengalis"; to distinguish this region from India's state West Bengal, East Pakistan was known as "Pakistani Bengal". In 1971, East Pakistan became the newly independent state Bangladesh, which means "country of Bengal" or "country of Bengalis" in the Bengali language.
