The state of Andhra Pradesh was formed on November 1, 1956, following the implementation of the States Reorganization Act of 1956.12

Under this act, the state of Hyderabad was dissolved. Its Telugu-speaking districts, which constitute the region of Telangana, were merged with the existing Andhra state to create the new, unified state of Andhra Pradesh.12

This development followed the earlier creation of Andhra state on October 1, 1953, which had been formed from the Telugu-speaking districts of the former Madras state after intense public demand for a linguistic state. The 1956 reorganization was part of a broader national effort to redraw India's internal administrative boundaries along linguistic lines.23
