Metz

The Prince-Bishopric of Metz was an ecclesiastical state of the Holy Roman Empire, distinct from the free imperial city of Metz. In 1337 its bishop was Aymar Adhémar de Monteil de La Garde.

Aymar fought for Philip VI of France at Crécy in 1346; Charles IV confirmed the bishopric's imperial immediacy in 1357. Lorraine princes held the see from 1484. Under the Treaty of Chambord, Henry II of France occupied Metz, Toul and Verdun in 1552; the Empire recognized their loss in the 1648 Peace of Westphalia.
