Question

How did nationalism affect the political goals of the country of Serbia?

Serbs wanted to unify all of the Slavic countries of the Balkan Peninsula with the Austro-Hungarian Empire.
Serbs wanted to declare independence from the Ottoman Empire, as other Slavic countries had done.
Serbs wanted the Slavic areas of Austria-Hungary to separate from the empire and become a part of Serbia.
Serbs wanted to overthrow the government of Austria-Hungary, unify the Slavic people, and take over the empire's territory.

Answer 1

I'm not sure about this answer but anyway...

Step-by-step explanation:

Nationalism is basically identifying with one's country's interests and culture and also eliminating and discouraging foreign influences.

So, the nationalists of Serbia wanted to save their culture and possibly some form of "race" from the Ottoman empire.
