International Mother Language Day, proclaimed by the UNESCO General Conference on November 17, 1999, has been celebrated every year on February 21 since 2000 to promote linguistic and cultural diversity and multilingualism.
In turn, the UN General Assembly in its resolution declared 2008 the International Year of Languages. 2010 was proclaimed the International Year for the Rapprochement of Cultures.
The date for the Day was chosen to commemorate the events that took place in Dhaka (now the capital of Bangladesh) on February 21, 1952, when students who demonstrated in defense of their native language Bengali, which they demanded to be recognized as one of the state languages of the country, were killed by police bullets. .
