What is the Instrument of Accession?

The Instrument of Accession was a legal document used in 1947 to enable rulers of princely states under British paramountcy to join one of the new dominions of India or Pakistan created by the Partition of British India. It was the constitutional mechanism through which 565 princely states were integrated into independent India.

Under the Indian Independence Act 1947, British suzerainty over the princely states ended on 15 August 1947. Since these states were not British possessions but tied to the Crown through treaties, they could not be partitioned; each ruler had the technical right to join India, join Pakistan, or remain independent. The Instrument required accession on only three subjects: defence, external affairs, and communications, leaving all other matters to the states.

Through the efforts of Sardar Vallabhbhai Patel (Home Minister and Deputy PM) and V.P. Menon (Secretary, States Department), almost all princely states within India's geographical limits had acceded by 15 August 1947. The three notable holdouts were Hyderabad (integrated through Operation Polo, September 1948), Junagadh (acceded after plebiscite), and Jammu & Kashmir (acceded on 26 October 1947 during the Pakistan-backed tribal invasion).
