The 1770 Ottoman Invasion of Mani was one of a series of invasions by the Ottomans to subdue the Maniots. Mani was one region of Greece that the Ottomans had not occupied due to the rough terrain and the rebellious spirit of Maniots. The Maniots caused damage to the Ottomans by allying with the Venetians whenever there was a war between Venice and the Ottomans, and also habitually engaged in piracy.
