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.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
