German nationalism (German: Deutscher Nationalismus) is an ideological notion that promotes the unity of Germans and of the Germanosphere into one unified nation-state. It emphasises and takes pride in the patriotism and national identity of Germans as one nation and one people. German nationalism, and the concept of nationalism itself, began during the late 18th century, which later gave rise to Pan-Germanism. Advocacy of a German nation-state became an important political force in response to the invasion of German territories by France under Napoleon Bonaparte. In the 19th century, Germans debated the German question over whether the German nation-state should comprise a "Lesser Germany" that excluded the Austrian Empire or a "Greater Germany" that included the Austrian Empire or its German speaking part. The faction led by Prussian Chancellor Otto von Bismarck succeeded in forging a Lesser Germany. Aggressive German nationalism and territorial expansion were key factors leading to both World Wars. Before World War I, Germany had established a colonial empire, which became the third-largest, after Britain and France. In the 1930s, the Nazis came to power and sought to unify all ethnic Germans under the leadership of Adolf Hitler, eventually leading to the extermination of Jews, Poles, Romani, and other people deemed Untermenschen (subhumans) in the Holocaust during World War II. After the defeat of Nazi Germany, the country was divided into East and West Germany in the opening acts of the Cold War, and each state retained a sense of German identity and held reunification as a goal, albeit in different contexts. The creation of the European Union was in part an effort to harness German identity to a European identity. West Germany underwent its economic miracle following the war which led to the creation of a guest worker program; many of these workers settled in Germany which led to tensions around questions of national and cultural identity, especially with regard to Turks who settled in Germany. German reunification was achieved in 1990 following Die Wende, an event that caused some alarm both inside and outside Germany. Germany has emerged as a great power in Europe and in the world; its role in the European debt crisis and the European migrant crisis led to criticism of German authoritarian abuse of its power, especially with regard to the Greek debt crisis, and raised questions within and outside Germany as to its global role. Due to post-1945 repudiation of the Nazi regime and its atrocities, German nationalism has generally been viewed in the country as taboo, and people within Germany have struggled to find ways to acknowledge its past while taking pride in its accomplishments. A wave of national pride swept the country during the 2006 FIFA World Cup. Far-right parties that stress German national identity and pride have existed since the end of World War II but have never governed. According to the Correlates of War project, patriotism in Germany before World War I ranked at or near the top, whereas today it ranks at or near the bottom of patriotism surveys. However, there are also other surveys according to which modern Germany is indeed very patriotic. Source: Wikipedia (en)
