The Battle of Wai was fought in December of 1687 as a part of the Mughal–Maratha Wars. Maratha king Sambhaji sent his forces to counteract Sarja Khan, sent by Aurangzeb for the purpose of conquering Raigad.

Background In April 1685, Mughal emperor Aurangzeb managed to consolidate his power by first capturing Maratha allies, the Muslim kingdoms of Golconda and Bijapur. He broke his treaties with both kingdoms, attacked them and captured them by September 1686. While Aurangzeb was away at the Siege of Golconda, the Mughals invaded Satara district. And after his victory at Golconda, Aurangzeb was able to concentrate on the Marathas."Maharashtra State Gazetteers: Satara" Maharashtra (India), Gazetteers Dept.
