How did nationalism kill archduke Franz Ferdinand?

Nationalism allows the people of the country to govern and design their government structure. Monarchism has a royal family that rules a nation or many nations. The Monarch has the right to do whatever he or she feels to the people of his or her nation or nations. The people of Europe were fed up with the way they were treated by the aristocracy and the Monarchs of Austria/Hungary and Germany. They wanted their own self rule and government design. Some Serbians, who the Monarchs of Austria and Hungry treated like dirt (and some Bosnians I think), plotted together to kill the Archduke Ferdinand of Hungary. They wanted the monarchs gone and no longer able to rule and harm them. This his how nationalism killed Archduke Ferdinand. It was also the spark of the crazy war of World War 1.
