GERMAN WAR ENSIGN WWI

The German War Ensign flag was in common use in World War I. It had Prussia's national colours of white, the eagle of Prussia, with the German imperial black-white red tricolour in the upper canton with an Iron Cross.

In 1919, the flags of the German Empire were scrapped and replaced by those of the Weimar Republic. German nationalists used the old flag in protest against the Weimar Republic during the 1920s and 1930s.
