The Prince-Bishopric of Liège was a significant ecclesiastical principality in what is now modern-day Belgium. Established in the early Middle Ages, it was ruled by a prince-bishop who held both spiritual and temporal authority. The region was known for its rich cultural heritage and played a vital role in the political landscape of the Holy Roman Empire. Liège was an important center for trade and industry, particularly during the late medieval period. The prince-bishops were influential figures, often involved in regional conflicts and alliances. The city of Liège itself became a hub for education and the arts, contributing to the area's historical significance.
