With the introduction of 14 Indian languages in an officially recognized category named "scheduled languages" by the
Government of India in the year 1950, in which
Meitei language was not included, there was a language movement advocated by the literary, political and social associations as well as organizations, from
Northeast India (especially from
Manipur,
Assam and
Tripura), spearheaded especially by the
Manipuri Sahitya Parishad and the "All Manipur Students' Union" (AMSU), demanding the "scheduled language" status for
Meitei language (officially called
Manipuri language) for more than four long decades. In the year 1992,
Meitei language (officially called
Manipuri language) was given the "scheduled language" status with the
"71st Constitutional Amendment Act" of the
Indian Constitution. The day of the inclusion of Meitei language in the
Eighth Schedule to the Constitution of India and making it one of the
official languages of the Indian Republic is annually commemorated as
Meitei Language Day (also called
Manipuri Language Day) on August 20. == Classical language movement ==
