Trois-Évêchés
The name Trois-Évêchés ( German "three dioceses" ) stood for the three former prince-bishops (Hochstifte) Metz , Toul and Verdun in the church province of Trier . In 1552 the bishoprics were occupied by King Henry II of France, in accordance with the provisions of the Treaty of Chambord . Although in fact now under French control, they nominally remained in the Holy Roman Empire . With the Peace of Westphalia of 1648, France was confirmed the official possession of the Hochstifte.
Until the French Revolution , the Trois-Évêchés formed the province of the three dioceses .
