Answer:
The Serbs and Bosnians showed Nationalism because they had strong feelings of pride about their Ethnic Group, and they wanted their own independent Slavic country.
Step-by-step explanation:
Nationalism is the term used to describe a strongly positive feeling about the members of a nation, about everything that is generated in it, whether people or objects. Nationalists have a strong sense of belonging and a powerful and influential national identity in their lives.
The struggle of Serbs and Bosnians for independence of their territories is a strong example of nationalism, where these two peoples defended their ethnic groups and claimed that they were strong, unstoppable and that they deserved to have a free and sovereign nation.
