The Mughal Empire is conventionally said to have been founded in 1526 by Babur, a ruler from what is today Uzbekistan, who employed aid from the neighboring Safavid and Ottoman Empires to defeat the sultan of Delhi, Ibrahim Lodi, in the First Battle of Panipat and to sweep down the plains of North India. The Mughal imperial structure, however, is sometimes dated to 1600, to the rule of Babur's grandson, Akbar. This imperial structure lasted until 1720, shortly after the death of the last major emperor, Aurangzeb, during whose reign the empire also achieved its maximum geographical extent. Reduced subsequently to the region in and around Old Delhi by 1760, the empire was formally dissolved by the British Raj after the Indian Rebellion of 1857.
