International Mother Language Day
Every language is a unique window on the world — preserve them all.
About
International Mother Language Day on February 21 promotes linguistic and cultural diversity and multilingualism. It is estimated that more than half of the approximately 7,000 languages spoken worldwide are at risk of disappearing by the end of this century, with one language lost on average every two weeks. UNESCO uses the day to advance the understanding that languages and multilingualism foster inclusion and the achievement of quality education for all.
History
The date commemorates the killing of students in Dhaka, Bangladesh (then East Pakistan) on February 21, 1952, who demonstrated for the right to use their native Bengali language. UNESCO proclaimed the day in November 1999, and it has been observed globally since February 2000. Bangladesh's Language Movement is now a powerful symbol of linguistic rights worldwide.
Where It's Observed
Cultural Context
US United States
The US is home to over 400 languages, including Indigenous tongues many of which are critically endangered. The day prompts discussions about language education policy, bilingual schooling, and the preservation of Native American languages.
KR South Korea
South Korea's Hangul script — invented by King Sejong in 1443 — is celebrated as one of the world's most scientific writing systems. The day reinforces pride in Korean linguistic identity and prompts advocacy for Korean language preservation among diaspora communities worldwide.
JP Japan
Japan's linguistic identity is complex: Japanese coexists with Ryukyuan languages and the endangered Ainu language of Hokkaido. The day prompts awareness campaigns about Ainu cultural preservation and respect for linguistic diversity within Japan.
