The Adil Shahi or Adilshahi, was a Shia Muslim dynasty, founded by Yusuf Adil Shah, that ruled the Sultanate of Bijapur, centered on present-day Bijapur district, Karnataka in India, in the Western area of the Deccan region of Southern India from 1489 to 1686. Bijapur had been a province of the Bahmani Sultanate (1347–1518), before its political decline in the last quarter of the 15th century and eventual break-up in 1518.
