What country colonized most of north American's East coast?

Great Britain colonized most of North America's East Coast, establishing several colonies from the early 17th century onward. The British influence was prominent in areas that would later become the United States, particularly in New England, the Mid-Atlantic, and the Southern colonies. Other European powers, such as France and Spain, also had territories in North America, but Britain's presence was the most significant in shaping the early history and development of the region.
