Europeans began building their empires in the western hemisphere in the early 1500s, but by the 1800s, Spain and Portugal were no longer powerful countries, and the largest British colony had become the United States. Britain, France, Germany, Russia, and the Netherlands continued to colonize during this era, but they also devised other ways to spread their empires. In the late 19th century Japan and the United States joined the European nations as an imperialist power.
