Daulatabad Fort originally Deogiri Fort, is a historic fortified citadel located in Daulatabad village near Chhatrapati Sambhajinagar, 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 Sambhajinagar Maharashtra, 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 the city 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.In 1499, Daulatabad became a part of the Ahmadnagar Sultanate, who used it as their secondary capital. In 1610, near Daulatabad Fort, the new city of Aurangabad, then named Khadki, was established to serve as the capital of the Ahmadnagar Sultanate by the Ethiopian military leader Malik Ambar, who was brought to India as a slave but rose to become a popular Prime Minister of the Ahmadnagar Sultanate. Most of the present-day fortifications at Daulatabad Fort were constructed under the Ahmadnagar Sultanate.
