Anti-German sentiment (also known as anti-Germanism, Germanophobia or Teutophobia) is fear or dislike of Germany, its people, and its culture. Its opposite is Germanophilia.
Traces of anti-German sentiment can be found in the High Middle Ages, with Ekkehard of Aura and Odo of Deuil writing about frictions between the Germans and the French. After Germany completed its unification in 1871, anti-Germanism grew among the other great powers, fueled largely by fears of Germany's rapid industrialisation. Germanophobia reached its height in the Allied countries during World War I and World War II. Anti-German and anti-Austrian sentiments were generally held together, as Austrians worked with and were involved in the German military, especially in Nazi Germany, with most Austrians considering themselves German until the end of World War II in Europe.
