In 1323 the sultan of Delhi, Ghiyath al-Din Tughluq, sent a large army commanded by Ulugh Khan (later, as Muhammad bin Tughluq, the Delhi sultan) to conquer the Telugu region and lay siege to Warangal. The fall of the Kakatiya Dynasty led to an era with competing influences from the Turkic kingdoms of Delhi, the Chalukya Chola dynasty (1070–1279) in the south and the Persio-Tajik sultanate of central India. The struggle for Andhra ended with the victory of the Musunuri Nayaks over the Turkic Delhi Sultanate.
