How did the United States attempt to avoid future wars in
the years following World War I?

To prevent an arms race that could lead to another world war, America signed a number of disarmament treaties to limit the size of naval fleets among Britain, France, Italy, Japan, and the United States.

Contributing factors  leading  to the harlem renaissance were the great migration of african americans to northern cities, which concentratedambitious  people in places where they could encourage each  other, and the first world war, which had created new industrial work opportunities for tens of thousands of people.
