What has been a direct effect of nationalism in europe

Nationalism is characterized as distinguishing proof with one's very own country and support for its regard, especially to the avoidance or weakness of the interests of different countries.

The break apart of the Austro-Hungarian Empire has been an immediate impact of nationalism in Europe.

The Austro-Hungarian Empire was separated because of a few ethnicities residing in the empire with various beliefs and cultures. Nationalists made various cultural groups in order to join their efforts and call for autonomy to make country states.
