The Mughal empire is conventionally said to have been founded in 1526 by Babur, a warrior chieftain from what is today Uzbekistan, who employed military aid in the form of matchlock guns and cast cannon from the Ottoman Empire, and his superior strategy and cavalry to defeat the Sultan of Delhi, Ibrahim Lodhi, in the First Battle of Panipat, and to sweep down the plains of Upper India, subduing Rajputs and Afghans. The Mughal imperial structure, however, is sometimes dated to 1600, to the rule of Babur's grandson, Akbar, This imperial structure lasted until 1720, until shortly after the death of the last major emperor, Aurangzeb, during whose reign the empire also achieved its maximum geographical extent. Reduced subsequently, especially during the East India Company rule in India, to the region in and around Old Delhi, the empire was formally dissolved by the British Raj after the Indian Rebellion of 1857.
