Since the independence of India, the Scheduled Castes (SC) and Scheduled Tribes (ST) have been given Reservation status, guaranteeing political representation, and the Constitution lays down the general principles of positive discrimination for STs and SCs.

[5][6] The Scheduled Tribes have been granted a reservation of 39 seats in the Mizoram assembly, leaving only one (Aizawl East-I) unreserved.

[7] Mizoram became a Union Territory of India in 1972, at which time it was assigned a 30-member legislative assembly and it had its first election.

[8] In 1986, after the Mizoram Peace Accord was signed, the 53rd Amendment to the Constitution of India was passed.

Mizoram was officially converted into a state in February 1987, and the number of constituencies for its legislative assembly was increased to 40.
