International Mother language Day

Mother language Day:
21 February was proclaimed the International Mother Language Day by UNESCO on 17 November 1999. Its observance was also formally recognized by the United Nations General Assembly in its resolution establishing 2008 as the International Year of Languages. International Mother Language Day originated as the international recognition of Language Movement Day, which has been commemorated in Bangladesh (formerly East Pakistan) since 1952, when a number of Dhaka university students were killed by the Pakistani police and army in Dhaka during the Bengali Language Movement.
Around 1950-52, the emerging middle classes of East Bengle underwent an uprising known later as the Bangla language. Movement. Bangladeshis (then East Pakistanis) were initially agitated by a decision by the Central Pakistan Government to establish Urdu, a minority language spoken only by the supposed elite class of West Pakistan, as the sole national language for all of Pakistan. The situation was worsened by an open declaration that "Urdu and only Urdu will be the national language of Pakistan" by the governor, Khawaja Nazimuddin
Protest:
Police declared Section 144 which banned any sort of meeting. Defying this, the students of University of Dhaka and Dhaka Medical College and other political activists started a procession in February 21, 1952. Near the current Dhaka Medical College Hospital, police fired on the protesters and numerous people, including Abdus Salam, Rafiq Uddin Ahmed, Sofiur Rahman, Abul Barkat and Abdul Jabbar, died. The movement spread to the whole of East Pakistan and the whole province came to a standstill. Afterwards, the Government of Pakistan relented and gave Bangla equal status as a national language.
Effects:
This movement is thought to have sown the seeds for the independence movement which resulted in the liberation of Bangladesh in 1971.To commemorate this movement, Shaheed Minar a solemn and symbolic sculpture, was erected in the place of the massacre. The day is revered in Bangladesh and, to a somewhat lesser extent, in West Bengal as the Martyrs' Day. UNESCO decided to observe as International Mother language Day. The UNESCO General Conference took a decision to that took effect on 17 November 1999 when it unanimously adopted a draft resolution submitted by Bangladesh and co-sponsored and supported by 28 other countries.
