The present city of Allahabad was founded in 1583 by the Mughal emperor Akbar, who named it al-Ilahābād (“City of God”). It became a provincial capital in the Mughal Empire (Mughal Dynasty), and from 1599 to 1604 it was the headquarters of the rebellious prince Salim (later the emperor Jahangir (Jahāngīr)). Outside Allahabad fort is the tomb built for Jahangir's rebellious son, Khusru. With the Mughal decline, Allahabad changed hands many times before being ceded to the British in 1801. The city was the scene of a great massacre during the 1857–58 Indian Mutiny against British rule. From 1904 to 1949 the city was the capital of the United Provinces (now Uttar Pradesh). It was a centre of the Indian independence movement and was the home of the Nehru family, whose estate is now a museum.

Primarily an administrative and educational centre, Allahabad has some industry (food processing and manufacturing) and is a marketplace for agricultural products. The administrative and professional sector and the military cantonment are located north of the city proper. The city is a major road and rail centre and is served by a nearby airport.
