21st February is observed with pride in Bangladesh. This day is memorable for the language movement that took place in 1952. Then, Bangladesh was known as East Pakistan. After the British rule was over or after the partition of 1947, the Pakistani rulers declared Urdu as the only state language. Majority of the people of East Pakistan spoke Bangla as their Mother language. They could not accept this declaration and started protesting seriously. Fie! Fie upon the then Pakistan rulers!
