In 2014, these merged areas of Hyderabad State were bifurcated from United Andhra Pradesh to form the new state Telangana. The present form of Andhra is similar to Andhra state, but some mandalas like Bhadrachalam are still included in Telangana. Amaravati serves as the capital of the state with the largest city being Visakhapatnam.[18]
