Context: President of India and Prime Minister of India congratulated the people of Tripura, Manipur, and Meghalaya on the occasion of their Statehood Day.
Emergence of new States:
Fazl Ali Commission: It suggested the abolition of the four-fold classification of states and territories under the original Constitution and creation of 16 states and 3 centrally administered territories.
States Reorganisation Act (1956) and the 7th Constitutional Amendment Act (1956): The distinction between Part A and Part B states was done away with and Part C states were abolished. As a result, 14 states and 6 union territories were created on November 1, 1956.
Later changes: Even after the large-scale reorganisation of the states in 1956, the political map of India underwent continuous changes due to the pressure of popular agitations and political conditions.
Manipur, Tripura and Meghalaya
In 1972, the political map of Northeast India underwent a major change.
The two union territories of Manipur and Tripura and the sub-state of Meghalaya got statehood and the two union territories of Mizoram and Arunachal Pradesh (originally known as North-East Frontier Agency–NEFA) came into being.
Initially, the 22nd Constitutional Amendment Act (1969) created Meghalaya as an ‘autonomous state’ or ‘sub-state’ within the state of Assam with its own legislature and council of ministers.
However, this did not satisfy the aspirations of the people of Meghalaya. The union territories of Mizoram and Arunachal Pradesh were also formed out of the territories of Assam.
