Bangla is the official language of Bangladesh. Bangalees had to sacrifice lives for their mother tongue on 21st February, 1952. The UNESCO has declared 21st February as The International Mother Language Day to be observed globally in recognition of the sacrifices of the Bangla language martyrs who laid their lives for establishing the rightful place of Bangla.
The proclamation came in the form of a resolution unanimously adopted at the plenary of the UNESCO at its headquarters in Paris in November 1999. In its resolution the UNESCO said –
“21st February be proclaimed International Mother Language Day throughout the world to commemorate the martyrs who sacrificed their lives on this very day in 1952”.
The UNESCO in its resolution said the recognition was given bearing in mind that all moves to promote the dissemination of mother tongues will serve not only to encourage linguistic diversity and multilingual education but also to develop fuller awareness about linguistic and cultural traditions throughout the world and to inspire solidarity based on understanding, tolerance and dialogue. Henceforth UN member countries around the world will observe 21st February as the International Mother Language Day.
