How did the States Reorganization Act of 1956 shape Rajasthan?

The States Reorganization Act of 1956 was the final step in the administrative consolidation of the region, allowing Rajasthan to assume its present-day geographical form on November 1, 1956.1

Following India's independence in 1947, the region—formerly known as Rajputana—consisted of approximately two dozen princely states, chiefships, and the British-administered province of Ajmer-Merwara. These territories were integrated into a single entity in stages, moving through the formation of smaller unions like the Matsya Union and the Rajasthan Union, before creating "Greater Rajasthan" in 1949.12

The implementation of the 1956 Act finalized these boundaries, formally incorporating areas such as the former chief commissioner’s province of Ajmer-Merwara into the state. This reorganization solidified the state's identity as an integral part of India, concluding the transition from a collection of princely states to a unified administrative unit.231
