Daulatabad Fort, originally Devagiri Fort, is a historic fortified citadel located in Daulatabad village near Aurangabad, Maharashtra, India. It was the capital of the Yadavas (9th century – 14th century CE), for a brief time the capital of the Delhi Sultanate (1327–1334), and later a secondary capital of the Ahmadnagar Sultanate (1499–1636).
Around the 6th century CE, Devagiri emerged as an important uplands town near present-day Aurangabad, along caravan routes going towards western and southern India. The historical triangular fortress in the city was initially built around 1187 by the first Yadava monarch, Bhillama V. In 1308, the city was annexed by Alauddin Khalji of the Delhi Sultanate, which ruled over some parts of the northern India. In 1327, Muhammad bin Tughluq of the Delhi Sultanate renamed Devagiri as Daulatabad and shifted his imperial capital to the city from Delhi, ordering a mass migration of Delhi's population to the now Daulatabad. However, Muhammad bin Tughluq reversed his decision in 1334 and the capital of the Delhi Sultanate was shifted back to Delhi.
