Bahmani Sultanate
The fall of Warangal to Muhammad bin Tughluq's forces from the Delhi Sultanate in 1321 AD brought anarchy to the region. Later, the Golkonda fort came under the control of the Musunuri Nayaks, who defeated the Tughlaqi army occupying Warangal. For the next few decades, the Bahmani Sultanate of the Deccan fought the Musunuri Nayakas on the north and the Vijayanagara Rayas on the south for control of the region. The Golkonda fort was ceded by the Musunuri Kapaya Nayak to the Bahmani Sultanate as part of a treaty in 1364. By the middle of the 15th century, the region was under the firm control of the Bahmani Sultanate, which controlled the Deccan north of the Krishna River from coast to of sultanate.
