The document summarizes the major European powers that led maritime exploration during the Age of Exploration: Portugal improved its navy under Prince Henry and was able to lead exploration in this era, controlling the east coast of South America.

France and England also competed for new lands, with France controlling the North American fur trade and England establishing colonies along the eastern United States coast.
