There is little difference between the usage of Bangla, Bangla and Bangla in West Bengal and its use, pronunciation and phonology:
Today, Bangla and its various dialects are the main languages of Bangladesh and the second most popular language in India. This language has created a rich tradition of Bengali literature created by the renaissance of Bengal and the cultural diversity of Bengal, not only this language but also Bengali One of the most important roles have been played in the formation of nationalism.
In 1951-52, the Bangla Language Movement organized in East Pakistan established links to Bengali existence with this language. On February 21, 1952, students and protesters protested at the University of Dhaka sacrificed their life in the name of demanding rights of speaking and writing in Bangla. In recognition of their sacrifices for mother tongue, in the year 1999, UNESCO announced the 21st February as the International Mother Language Day.
