Abstract
klephts (Greek κλέφτης, kléftis, pl. κλέφτες, kléftes, which means "thief" and perhaps originally meant just "brigand") were highwaymen turned self-appointed armatoloi, anti-Ottoman insurgents, and warlike mountain-folk who lived in the countryside when Greece was a part of the Ottoman Empire. They were the descendants of Greeks who retreated into the mountains during the 15th century in order to avoid Ottoman rule.
They carried on a continuous war against Ottoman rule and remained active as brigands until the 19th century
