Following is a brief history of Andhra Pradesh and chronology of the movement for Telangana state:
The region, now being called Telangana, was part of the erstwhile Hyderabad state which was merged into the Indian Union on September 17, 1948.
Central government appointed a civil servant, M K Vellodi, as the first Chief Minister of Hyderabad state on 26 January 1950. In 1952, Burgula Ramakrishna Rao was elected Chief Minister of Hyderabad state in the first democratic election.
Andhra was the first state to be carved out (from erstwhile Madras state) on linguistic basis on November 1, 1953. It had Kurnool town (in Rayalaseema region) as its capital after the death of Potti Sriramulu who sat on a 53-day fast-unto-death demanding the new state.
The proposal for amalgamation of Hyderabad state with Andhra state came up in 1953 and the then Chief Minister of Hyderabad state, Burgula Ramakrishna Rao, supported the Congress central leadership's decision in this regard though there was opposition in Telangana region.
Accepting the merger proposal, Andhra assembly passed a resolution on November 25, 1955 promising to safeguard the interests of Telangana.
An agreement was reached between Telangana leaders and Andhra leaders on February 20, 1956 to merge Telangana and Andhra with promises to safeguard Telangana's interests. A 'Gentlemen's Agreement' was then signed by Bezawada Gopala Reddy and Burgula Ramakrishna Rao to the effect.
Eventually, under the States Re-organisation Act, Telugu-speaking areas of Hyderabad state were merged with Andhra state, giving birth to the state of Andhra Pradesh on November 1, 1956.
The city of Hyderabad, the then capital of Hyderabad state, was made the capital of Andhra Pradesh state.
In 1969, an agitation began in Telangana region as people protested the failure to implement the Gentlemen's Agreement and other safeguards properly.
Marri Channa Reddy launched the Telangana Praja Samiti espousing the cause of a separate state. The agitation intensified and turned violent with students in the forefront of the struggle and about 300 of them were killed in violence and police firing that ensued.
Following several rounds of talks with leaders of the two regions, the then Prime Minister Indira Gandhi came up with an eight-point plan on April 12, 1969. Telangana leaders rejected the plan and protests continued under the aegis of Telangana Praja Samiti.
