Final answer:
Nationalism can either divide or unify societies. It can lead to conflicts between different groups but also create a shared sense of identity and purpose.
Step-by-step explanation:
Nationalism can both divide and unify societies. On one hand, nationalism can divide people by creating conflicts between different national or ethnic groups. For example, World War I was fueled by nationalism as various nations sought to assert their dominance. On the other hand, nationalism can also unify people by creating a shared sense of identity and purpose. For instance, the American Revolution was driven by a desire for independence and the establishment of a new nation.
