8. So what was everyone’s problem? Ethnic Groups! Many ethnic groups made up large empires in Europe (Austria-Hungary Empire) Each ethnic group wanted to be free of their empire to form their own country (Bosnia-Herzegovina or “Black Hand”) Each ethnic group felt nationalism towards their group not their country

9. Other problems in Europe Countries felt they needed strong militaries to be safe. As one country’s military increased, other countries felt unsafe and increased their military. This lead to countries making alliances with each other and becoming allies, incase a war ever broke out.
