Overview

An ecclesiastical principality in Friuli (northeastern Italy) whose patriarchs ruled as temporal princes over a substantial feudal state from the 11th century, having received extensive regalian rights from the Holy Roman Emperors (notably 1077). The patriarchate held a distinctive parliament (the Parlamento della Patria del Friuli, one of Europe's early representative assemblies). Weakened by feudal conflict and by rivalry with Venice and the counts of Gorizia, the temporal principality was conquered by the Republic of Venice in 1420, though the patriarchs retained ecclesiastical dignity until the see was suppressed in 1751 and replaced by the archbishoprics of Udine and Gorizia.
