Battle of Talikota
The Bijapur Sultanate's borders changed considerably throughout its history. Its northern boundary remained relatively stable, straddling contemporary Southern Maharashtra and Northern Karnataka. The Sultanate expanded southward, first with the conquest of the Raichur Doab following the defeat of the Vijayanagar Empire at the Battle of Talikota in 1565. Later campaigns, notably during the reign of Mohammed Adil Shah (1627–1657), extended Bijapur's formal borders and nominal authority as far south as Bangalore. Bijapur was bounded on the West by the Portuguese state of Goa and on the East by the Sultanate of Golconda, ruled by the Qutb Shahi dynasty.
