International Mother Language Day

21 February

The idea to celebrate International Mother Language Day was the initiative of Bangladesh. It was approved at the 1999 UNESCO General Conference and has been observed throughout the world since 2000.

UNESCO believes in the importance of cultural and linguistic diversity for sustainable societies. It is within its mandate for peace that it works to preserve the differences in cultures and languages that foster tolerance and respect for others.  

Multilingual and multicultural societies exist through their languages which transmit and preserve traditional knowledge and cultures in a sustainable way.

Linguistic diversity is increasingly threatened as more and more languages disappear.

Globally 40 per cent of the population does not have access to an education in a language they speak or understand. Nevertheless, progress is being made in multilingual education with growing understanding of its importance, particularly in early schooling, and more commitment to its development in public life.

"On  this  International  Mother  Language  Day,  UNESCO  is  calling  for  investment  in  language transmission by placing young people at the heart of the solutions involved. Because linguistic diversity is a pillar of peace, dignity and inclusion. And no voice should be missing from the story of our humanity."

2026 celebrations

This year’s International Mother Language Day highlights the role of young people in shaping the future of multilingual education. Youth voices on multilingual education emphasizes that language is more than a means of communication: it is central to identity, learning, well-being and participation in society. The celebration underscores the importance of education systems that recognise and value every learner’s language to support inclusion and learning outcomes.

Ahead of International Mother Language Day, UNESCO is organizing an online Campus event on 13 February. Students aged 13–18 can participate, engage via chat, and exchange with international experts and peers from all regions. The event offers a space for young people to share experiences and identify concrete actions to promote linguistic diversity in their schools and communities.

Through the UNESCO Campus “Many languages, one future: Youth voices on multilingual education” held on 13 February, students from around the world engaged directly with experts and partners to share why learning in a language learners understand is essential for inclusion, equity and quality education.

By convening young people, educators and international partners, UNESCO continues to promote policies and practices that ensure education systems reflect the linguistic realities of the communities they serve.
