Principality of Galilee
The Principality of Galilee was established by Tancred in 1099. The principality became the fief of the families of St. Omer, Montfaucon (Falcomberques), and then Bures, and its main seat was in Tiberias; thus it was sometimes also called the Principality of Tiberias or the Tiberiad. The Principality was destroyed by Saladin in 1187, although the title was used by relatives and younger sons of the kings of Cyprus (the titular kings of Jerusalem) afterwards.
The Principality also had its own vassals, the Lordships of Beirut, Nazareth, and Haifa, which often had their own sub-vassals.
