In page Montenegro:

"

Montenegrin territories were controlled by warlike clans. Most clans had a chieftain (knez), who was not permitted to assume the title unless he proved to be as worthy a leader as his predecessor. An assembly of Montenegrin clans (Zbor) was held every year on 12 July in Cetinje, and any adult clansman could take part.[4] In 1515, Montenegro became a theocracy led by the Metropolitanate of Montenegro and the Littoral, which flourished after the Petrović-Njegoš of Cetinje became the prince-bishop (whose title was "Vladika of Montenegro").[citation needed]
