"The Els\u00E4ssisches Fahnenlied (\"The Alsatian Flag's song\") was written by Emil Woerth (1870-1926) in German when Alsace was part of the German Empire (1871-1918). It was adopted as the official anthem of Alsace in the same year, in 1911.After World War I the short-lived Independent Republic of Alsace-Lorraine was back to France in late 1918."@en . . .
