Fürstentum Achaia
The Barony of Passavant or Passava was a medieval Frankish fiefdom of the Principality of Achaea, located in the mountains between the Mani peninsula and the plain of Laconia, in the Peloponnese peninsula in Greece, centred on the fortress of Passavant or Passava (). It was among the twelve original baronies of the Principality of Achaea, but was conquered by the Byzantines in the early 1260s.
