German Nationalism is a political and cultural movement that emphasizes the unity and identity of the German people. It emerged in the 19th century, particularly during the period of the German Confederation, and played a significant role in the unification of Germany in 1871 under Otto von Bismarck. This movement sought to promote a shared language, culture, and history among Germans. Throughout history, German Nationalism has had various expressions, sometimes leading to positive outcomes like national unity and cultural pride. However, it has also been associated with more extreme ideologies, particularly during the Nazi regime, which used nationalism to justify expansionist policies and discrimination against other groups.
