Present day Lonavla was a part of the Yadava dynasty. Later, the Mughals realized the strategic importance of the region and kept the region for an extended time. The forts in the region and the "Mavla" warriors played an important role in the history of the Maratha and Peshwa empires. In 1871, the Lonavla and Khandala hill stations were discovered by Lord Elphinstone, who was the Governor of Bombay Presidency at the time.
