The holiday was established by the decision of the 30th session of the General Conference of UNESCO in November 1999 and it has been annually celebrated since 2000 on February 21to promote awareness of linguistic and cultural diversity.
The decision to declare International Mother Language Day was supported by the UN General Assembly. It called on member states of the UN and the UN Secretariat to promote the preservation and protection of all languages used by peoples of the world.
According to UNESCO, half of the approximately 6 thousand languages of the world may soon lose their last native speakers. Every two weeks, one language disappears in the world.
Every year, events are held on this day to promote the protection of all languages and multilingualism.
