It is often associated with the region of Lorraine in northeastern France and has historical significance dating back to the medieval period. The design is commonly used in various flags, emblems, and coats of arms. In modern times, the Cross of Lorraine has been adopted as a symbol of resistance and freedom, particularly during World War II. It was used by the Free French Forces led by Charles de Gaulle to represent their fight against Nazi occupation.
