Additional Information As part of the North Eastern Region (Re-Organisation) Act, 1971, Tripura and Manipur, which had previously been princely states , were united into the Indian Union in October 1949 and were made complete states on January 21, 1972. The same act also led to Meghalaya's statehood, which was once a part of Assam . The princely states that had merged into the Indian Union had begun acquiring statehood soon after the nation had earned independence from British Rule . On the other hand, Meghalaya was still a part of Assam in 1949 , although Tripura and Manipur had been given the status of Union Territories. Later, in 1969, Meghalaya was recognised as an autonomous state due to the Assam Reorganisation (Meghalaya) Act .
