The County of Bar, from 1354 the Duchy of Bar, was a principality of the Holy Roman Empire comprising the pays de Barrois and centred on the city of Bar-le-Duc. Part of the county—the so-called Barrois mouvant—became a fief of the Kingdom of France in 1301, while the Barrois non-mouvant remained a part of the Empire. From 1480 it was united to the imperial Duchy of Lorraine. Both imperial Bar and Lorraine were ceded to France in 1738. With the death of the last duke, Stanislaus Leszczynski, in 1766 the duchy escheated to the French crown.
