The House of Andechs was a feudal line of German princes in the 12th and 13th centuries. The counts of Dießen-Andechs (1100 to 1180) obtained territories in northern Dalmatia on the Adriatic seacoast, where they became Margraves of Istria and ultimately dukes of a short-lived imperial state named Merania from 1180 to 1248. They were also self-styled lords of Carniola.
