England
By the end of the 1600s, England controlled most of the eastern seaboard of North America. The English had established several colonies, including Virginia, Massachusetts, and Maryland, among others. This period marked significant territorial expansion and consolidation of English claims, particularly following the defeat of the Spanish Armada in 1588 and subsequent colonization efforts. Other European powers, such as France and the Netherlands, held territories but not to the extent of English control along the coast.
