Why did the USA wish to further expand its interests overseas?

Up until 1890, as the USA was emerging as one of the world’s greatest economic and military powers, they had been pursuing a policy of Isolationism.

Following the War of Independence with Britain, which had lasted from 1775-1783, the US was focusing on developing its own political system and fighting for economic stability.
