The 22 states that formed the state of Rajasthan 22 months after independence in 1947 were part of the Rajputana Agency under the British Empire in India. It spanned 330,000 square kilometres with an agent under the Governor General in charge at Mount Abu. All had Hindu rulers except Tonk and most of them were Rajput except for Jat rulers in Bharatpur and Dholpur. These states were not affected by the 1857 revolt against British rule because they remained loyal to the British.

Sardar Patel, deputy prime minister, headed the States Ministry with VP Menon as Secretary. The integration to form the new state happened in stages. The first union was the Matsya Union of Alwar, Bharatpur, Dholpur, Karauli, at the eastern edge of the Rajputana Agency by March 18, 1948. Nine other states near Udaipur in the south east merged to form the Rajasthan Union by March 25, 1948. On March 30, 1949, Patel pulled in 4 states bordering Pakistan, Jodhpur, Jaisalmer, Jaipur, and Bikaner into Greater Rajasthan. The Matsya Union was merged into this state. In 1956 under States Reorganization Act Ajmer was added from federal rule and Abu Taluk was integrated into Rajasthan.
