IV. Telengana:

On 17 September 17 1948 Hyderabad state, which included Telangana, was merged into the Indian Union. It is well known fact that the States Reorganization Commission (SRC) did not favour the idea of merging Telangana with Andhra Pradesh and it provided various safeguards to protect the interests of the people of the region for some years to come. Telangana was merged with Andhra to form Andhra Pradesh in 1956. In 1969, an agitation began in the region under Marri Channa Reddy under the banner of Telengana Praja Samiti. The struggle continued without any success for a long time.

The Telengana Rashtra Samiti then took the cause of separate Telengana is 2001. On November 29, 2009, the TRS launched an indefinite hunger strike. On 9 December 2009, the centre announced that it was "initiating the process for formation of Telengana State". Finally in 2014, the demand was fulfilled, after much dilly-dallying, Telangana became 29th State of India on. `
