Of all the feudal lordships, founded in Northern Greece at the time of the Frankish Conquest, the most important and the most enduring was the Marquisate of Boudonitza. Like the Venieri and the Viari in the two islands of Cerigo and Cerigotto at the extreme south, the lords of Boudonitza were Marquesses in the literal sense of the term—wardens of the Greek Marches— and they maintained their responsible position on the outskirts of the Duchy of Athens until after the establishment of the Turks in Thessaly. Apart, too, from its historic importance, the Marquisate of Boudonitza possesses the romantic glamour which is shed over a famous classical site by the chivalry of the middle ages. What stranger accident could there have been than that which made two noble Italian families the successive guardians of the historic pass which is for ever associated with the death of Leonidas.
