Ahmedabad is the largest city in the state of Gujarat and the seventh-largest urban agglomeration in India. Located on the banks of the River Sabarmati, the city is the administrative centre of Ahmedabad district, and was the capital of Gujarat from 1960 to 1970; the capital was shifted to Gandhinagar thereafter. Although incorporated into the Bombay Presidency during the British rule in India, Ahmedabad remained the most important city in the Gujarat region. The city established itself as the home of a booming textile industry, which earned it the nickname "the Manchester of the East.” The city was at the forefront of the Indian independence movement in the first half of the 20th century.
