Dvořák, the Czech composer, wrote a song cycle named Three Modern Greek Poems: the first one is entitled "Koljas - Klepht Song" and tells the story of Koljas, the klepht who killed the famous Ali Pasha.
In the 19th century, he achieved a prominent position among the other klepht leaders, and led the fight against Ali Pasha, the powerful and semi-independent Ottoman governor of Yanina.
