About International Mother Language Day

International Mother Language Day is the UNESCO observance held on 21 February to promote linguistic and cultural diversity, multilingualism and the importance of learning and public life in languages people understand.

A mother language can be deeply connected to family, identity, memory and community knowledge. The observance also highlights the practical importance of multilingual education and access to information across languages.

Why International Mother Language Day matters

Language diversity matters both culturally and practically. People participate more fully in education and public life when language barriers are recognized, and communities can preserve knowledge and traditions through continued use of their languages.

The day should not be used to rank languages as more or less valuable. Respectful observance supports multilingualism and the choices communities make about maintaining, teaching and documenting their languages.

History of International Mother Language Day

The idea for International Mother Language Day was initiated by Bangladesh and approved at UNESCO’s General Conference in 1999. It has been observed internationally since 2000.

The date, 21 February, commemorates the 1952 language movement in what was then East Pakistan, when demonstrators in Dhaka campaigning for recognition of Bangla were killed. That history explains Bangladesh’s proposal and the choice of date.

On 15 February 2002, the United Nations General Assembly adopted resolution A/RES/56/262 on multilingualism, welcoming UNESCO’s 1999 decision to proclaim 21 February as International Mother Language Day. The guide stores that UN action as later recognition rather than rewriting UNESCO’s original establishing role.
