Well, “America” as a whole was a series of separated colonies with different founding dates. The oldest (Virginia) was founded in 1607 and the united colonies which became the United States declared independence in 1776, but really didn't achieve it until 1783. So I would say about 170 years, give or take.
Similarly one may ask, when did the British arrive in America?
The first colony was founded at Jamestown, Virginia, in 1607. Many of the people who settled in the New World came to escape religious persecution. The Pilgrims, founders of Plymouth, Massachusetts, arrived in 1620. In both Virginia and Massachusetts, the colonists flourished with some assistance from Native Americans.
When was the US under British rule?
The result of this view was the American Revolution, which began in 1776 and resulted in the defeat of the British in 1783. The Thirteen Colonies became the United States of America. The British did not leave North America, however.
