Question

How did nationalism contribute to the unrest in Europe that led to World War 1?

Answer 1

No, something more extreme than nationalism started World War I.

A beast called jingoism. It is the fiercest kind of nationalism. It spawns the kind of people who get testy when ANYONE questions the authority, power, and/or superiority of their country.

Yeah, pretty crazy s**z I know.

Answer 2

Germans wanted to expand the fatherland, so they invaded other countries. Then the nationalist group, called the black hand, shot the Archduke of Austria, Franz Ferdinand. That event was the straw that broke the camel's back and started war.

Answer 3

Nationalistic interests in Germany and the Balkans intervened. The Germans wanted to expand to gain more territory for their country, and the Serbia and Bosnia wanted to unite as slavic brothers. Germany's ally Austria-Hungary would not allow this, and eventually Bosnian-Serb assassin Gavrilo Princip, a member ot the "Black Hand", assassinated Archduke Franz Ferdinand of Austria-Hungary. This sparked an ultimatum to surrender to the Serbs from the Austrians, and the nationalistic interests intervened, causing the start of WWI.
