The States Reorganisation Act of 1956 was a major reform of the boundaries and governance ofIndia's states and territories. The act reorganised the boundaries of India's states along linguistic lines, and amended the Indian Constitution to replace the three types of states, known as Parts A, B, and C states, with a single type of state.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.
