The States Reorganisation Commission (SRC) was a body constituted by the Central Government of India in 1953 to recommend the reorganization of state boundaries along the linguistic lines. Some of its recommendations were implemented in the States Reorganisation Act of 1956. Although additional changes to India’s state boundaries have been made since 1956, the States Reorganisation Act of 1956 remains the single most extensive change in state boundaries since the independence of India in 1947. The Act came into effect at the same time as the Constitution (Seventh Amendment) Act, 1956, which (amongst other things) restructured the constitutional framework for India’s existing states.
