How did the Spanish take control of the land in the Americas?

The two powers vied for domination through the acquisition of the new land. The treaty in 1494 drew a north to south line through South America. Spain gained territory west of the line, while Portugal retained the lands east of the line including east coast of Brazil

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.
