Andhra State
On 1 October 1953, a separate Andhra State, consisting of the Telugu-speaking areas of the composite Madras State, with 167 constituencies with 190 seats in the Assembly, was formed. On 1 November 1956, Andhra State was merged with Hyderabad State under States Reorganisation Act, 1956, to form a single state, Andhra Pradesh. The districts of Raichur, Gulbarga, and the Marathwada district were detached from the Hyderabad State while merging with Andhra State. Besides, the Siruguppa taluk, the Bellary taluk, the Hospet taluk, and a small area of the Mallapuram sub-taluk were transferred from Mysore State to Andhra Pradesh. The districts of Raichur and Gulbarga were transferred to the Mysore State, while the Marathwada district was transferred to the Bombay State. This resulted in re-organization of assembly constituencies of Andhra Pradesh giving way to 85 constituencies with 105 seats in the assembly.
