Telangana Rashtra Samithi (TRS) is a regional political party in the southern Indian state of Andhra Pradesh. Its main agenda is the separation of the region of Telangana from Andhra Pradesh. Chandrashekhar Rao was a member of the Telugu Desam Party until he quit the party and formed the TRS in 2001. The party won one third of Mandal Parishad Territorial Constituencies (MPTC) and one quarter of Zilla Parishad Territorial Constituencies (ZPTC) in Telangana . In the 2004 assembly elections, the TRS formed an alliance with Congress (I) and won 26 state assembly seats. The party also won 5 parliament seats at the national level. It joined the governments at both state and central level. In September 2006 the party withdrew support for the central government on the grounds of indecision by the government over the delivery of its electoral promise to create Telangana, which was also put in the Common Minimum Program (CMP).
Rao assured the people of Telangana that the formation of the new state is on the cards and it can happen 'any moment'. On 13th September 2006, Rao triggered a by-election in his Lok Sabha constituency of Karimnagar. He was re-elected with a majority of more than 200,000.
