Leo Gabalas

Leo Gabalas (Greek: Λέων Γαβαλᾶς) was a Byzantine Greek magnate and independent ruler of a domain, centered on the island of Rhodes and including nearby Aegean islands, which was established in the aftermath of the dissolution of the Byzantine Empire by the Fourth Crusade in 1204. He acknowledged some form of suzerainty by the Empire of Nicaea, but remained virtually independent until his death, sometime in the early 1240s.
