Hyderabad is the capital and largest city of the Indian state of Telangana and the capital of Andhra Pradesh. It occupies 650 km2 (250 sq mi) on the Deccan Plateau along the banks of the Musi River, in the northern part of South India. With an average altitude of 542 m (1,778 ft), much of Hyderabad is situated on hilly terrain around artificial lakes, including the Hussain Sagar lake, predating the city’s founding, in the north of the city centre.

 According to the 2011 Census of India, Hyderabad is the fourth-most populous city in India with a population of 6.9 million residents within the city limits, and has a population of 9.7 million residents in the metropolitan region, making it the sixth-most populous metropolitan area in India. With an output of US$74 billion, Hyderabad has the fifth-largest urban economy in India.

As capital of the princely state of Hyderabad, the city housed the British Residency and cantonment until Indian independence in 1947. Hyderabad was annexed by the Indian Union in 1948 and continued as a capital of Hyderabad State (1948–56). After the introduction of the States Reorganisation Act of 1956, Hyderabad was made the capital of the newly formed Andhra Pradesh. In 2014, Andhra Pradesh was bifurcated to form Telangana and Hyderabad became the joint capital of the two states with a transitional arrangement scheduled to end in 2024. Since 1956, the city has housed the winter office of the President of India.

As of 2018, the most commonly used forms of medium-distance transport in Hyderabad include government-owned services such as light railways and buses, as well as privately operated taxis and auto rickshaws. These altogether serve 3.5 million passengers daily. Bus services operate from the Mahatma Gandhi Bus Station in the city centre with a fleet of 3800 buses serving 3.3 million passengers.
