Formation of Andhra Pradesh:
In December 1953, the States Reorganisation Commission was appointed to prepare for the creation of states on linguistic lines. Thus, merging the Telugu-speaking region of Hyderabad State (Telangana) with Telugu-speaking state of Andhra state, the Central Government, established a unified Andhra Pradesh on 1 November 1956.
Marri Chenna Reddy formed the Telangana Praja Samiti party to lead the Telangana movement. In November 1969, there was a major split in the party which eventually led to the downfall of the movement. He resigned his position to make room for a leader from Telangana to become the Chief Minister. On 30 September 1971, P. V. Narasimha Rao became the Chief Minister.
