The flag of Alsace, known as the Red-and-White (Rot-un-Wiss in the Alsatian dialect), is the original red and white flag of the region, and can be traced to the red and white banner of Gerard, Duke of Lorraine in the 11th century.

The original flag of Alsace, the Rot un Wiss, dates back to the red and white banner[1] of Gerard, Duke of Lorraine in the 11th century.

Perhaps as the Rot un Wiss marks the Germanic roots of Alsace, it was replaced in 1949 by a new flag, representing the union of the two départements of Haut-Rhin and Bas-Rhin, however without real historical relevance.

have erroneously called this a "Nazi invention"[citation needed] — while the Rot un Wiss is still known as the real historical emblem of the region by most of the population and the departments' parliaments.

Subsequently, the Rot un Wiss has been widely used during protests against the creation of a new "super-region" Grand Est, gathering Champagne-Ardennes, Lorraine and Alsace, namely on Colmar's statue of liberty.
