Zeta
Zeta was a principality in parts of Montenegro and northern Albania. It was once a Serbian crown land.
After Stefan Dušan's death in 1355, the Balšić family gained control as Serbia fragmented. Balša III passed Zeta to his uncle, the Serbian despot Stefan Lazarević, in 1421. The Crnojevići ruled from 1451; under Ottoman pressure Ivan moved his seat beneath Mount Lovćen in 1482 and founded the monastery around which Cetinje grew. His son Đurađ ruled until 1496.
