The Cross of Lorraine (French: Croix de Lorraine) was originally a heraldic cross. The two-barred cross consists of a vertical line crossed by two shorter horizontal bars. In most renditions, the horizontal bars are "graded" with the upper bar being the shorter, though variations with the bars of equal length are also seen. The Lorraine name has come to signify several cross variations, including the patriarchal cross with its bars near the top.
The Cross of Lorraine consists of one vertical and two horizontal bars.
The Cross of Lorraine came from the Kingdom of Hungary to the Duchy of Lorraine. In Hungary, Béla III was the first monarch to use the two-barred cross as the symbol of royal power in the late 12th century. He probably adopted it from the Byzantine Empire, according to historian Pál Engel.
René II, Duke of Lorraine inherited the two-barred cross as a symbol from his ancestors from the House of Anjou. His grandfather, René the Good, who used it as his personal sigil, laid claim to four kingdoms, including Hungary. The cross was still known as the "cross of Anjou" in the 16th century. René II placed the symbol on his flag before the Battle of Nancy in January 1477. In the battle, René defeated the army of Charles the Bold, Duke of Burgundy, who had occupied the Duchy of Lorraine, and regained his duchy. All coins struck for René bore the symbol thereafter.
The Cross of Lorraine is an emblem of Lorraine in eastern France. Between 1871 and 1918 (and again between 1940 and 1944), the north-eastern quarter of Lorraine was annexed to Germany, along with Alsace. During that period the Cross served as a rallying point for French ambitions to recover its lost provinces. This historical significance lent it considerable weight as a symbol of French patriotism. During World War II, Capitaine de corvette Thierry d'Argenlieu suggested the Cross of Lorraine as the symbol of the Free French Forces led by Charles de Gaulle as an answer to the Nazi swastika.
