[2][3][4] Meitei speaking people started living in Assam as a result of migration from Manipur due to the Chahi Taret Khuntakpa (literally, Seven Years' Devastation).

[15][16][17] A unique form of writing system called "Meetei Yelhou Mayek", distinct from the general Meitei script, was developed by Naoriya Phulo in Cachar, Assam.

[22] In the same year, Leishemba Sanajaoba, the titular king and an Indian member of Parliament of Manipur, wrote a letter to the government of Assam, to look into the matter.

The event is celebrated to honour the day on which Meitei was made an official language recognised by the Eighth Schedule to the Constitution of India.

In 2023, a Meitei language movie named "Nine Hills One Valley", directed by Haobam Pabankumar, was shown in the event.
