I just discovered that today is International Mother Language Day, and found this video about it:
According the the UN website,
“International Mother Language Day has been observed every year since February 2000 to promote linguistic and cultural diversity and multilingualism. The date represents the day in 1952 when students demonstrating for recognition of their language, Bangla, as one of the two national languages of the then Pakistan, were shot and killed by police in Dhaka, the capital of what is now Bangladesh.”
The theme for this year is books for mother tongue education.
