Although the Indian states were alternately requested or forced into union with either India or Pakistan, the real death of princely India came when the Twenty-sixth Amendment Act (1971) abolished the princes' titles, privileges, and privy purses.
The crucial document was the Instrument of Accession by which rulers ceded to the legislatures of India or Pakistan control over defence, external affairs, and communications. In return for these concessions, the princes were to be guaranteed a privy purse in perpetuity and certain financial and symbolic privileges such as exemption from customs duties, the use of their titles, the right to fly their state flags on their cars, and to have police protection. ... By December 1947 Patel began to pressure the princes into signing Merger Agreements that integrated their states into adjacent British Indian provinces, soon to be called states or new units of erstwhile princely states, most notably Rajasthan, Patiala and East Punjab States Union, and Matsya Union (Alwar, Bharatpur, Dholpur and Karaulli).
