International Mother Language Day is celebrated every year on 21st February. It was first announced by UNESCO on November 17, 1999. The main purpose of celebrating this day is to promote the awareness of language and cultural diversity all across the world.

Languages are the most powerful way to preserve and develop our tangible and intangible heritage. Azerbaijani language is the state official language of the Republic of Azerbaijan. There are over 50 million speakers of Azerbaijani at present.

The National Leader Heydar Aliyev made a great contribution to the state language development. A law “On the official language in the Republic of Azerbaijan” was adopted on September 30, 2002.

The language policy has been successfully continued by President Ilham Aliyev. A decree of the President of the Republic of Azerbaijan “On the carrying out of mass publications in Azerbaijani language with Latin script”, a decree “On the publication of the Azerbaijan National Encyclopedia”, “The State Program on the use of the Azerbaijani language in the context of globalization and the development of linguistics”, a decree "On measures to protect the purity of the Azerbaijani language and further improve the use of the state language", Order of the President of the Republic of Azerbaijan “On a number of measures to ensure wider use of Azerbaijani language in electronic space”, Order “On approval of the new composition of the State Language Commission of the Republic of Azerbaijan” are the most vivid illustrations of the state attention to the Azerbaijani language.
