Which of the following states joined the Indian Union in 1949?

Manipur joined the Indian Union in 1949. Key Points Manipur: Manipur, a princely state, acceded to the Indian Union on 15th October 1949, when its Maharaja signed the Instrument of Accession with the Indian government. This northeastern state has a rich cultural history and played a significant role in India's independence struggle against the British. Andhra Pradesh: Andhra Pradesh was formed on 1st October 1953, not in 1949. It was the first state in India to be formed on a linguistic basis, by carving it out from the Madras Presidency. Assam: Assam was already a part of British India and continued to be a state of the Indian Union post-independence in 1947. It did not join the Indian Union in 1949 like Manipur. Additional Information Integration of Princely States: The process of integrating the princely states into the Indian Union was a complex and critical task handled by Sardar Vallabhbhai Patel, the then Home Minister, and his secretary, V.P. Menon. By 1949, most princely states had acceded to India, with Manipur being one of the significant additions in that year.
