How did sovereignty change the way that european countries interacted with one another?

The correct answer is the following.

After many years of being part of one territory or belonging to the same empire, sovereignty changed the way European countries interacted with one another.

Powerful European nations started to divide, territories were split after war and treaties, and people started to live in different conditions. They became citizens of sovereign countries and had to get used to this new situation. Through diplomacy and accords, European countries began a new process in foreign affairs, politics, and trade. It was not an easy step for the social conditions then, but it represented a good step in autonomy and international relationships.
