Three Bishoprics
Quick Summary
The "Three Bishoprics" (Trois-Évêchés) refers to the historical territories of Toul, Metz, and Verdun in northeastern France. These areas were captured by the French king Henry II from the Holy Roman Emperor Charles V in 1552. France's ownership of these bishoprics was later confirmed in 1648 by the Peace of Westphalia.12
The Treaty of Verdun in 843, which divided the Carolingian Empire, is also associated with the region, as Verdun was the location where the treaty was signed. This treaty partitioned the empire among Charlemagne's grandsons, laying groundwork for the formation of modern European nations.31
