Early Europeans in this area near Fort Detroit in the 18th century were mostly French Canadians; some traded with the Sauk, Huron, and other Native Americans in the area. After defeating France in the Seven Years' War, Great Britain took control of their territory east of the Mississippi River, including Fort Detroit and environs. After the American Revolutionary War, Britain promoted development of what was then called Upper Canada and Province of Quebec, across the Detroit and St. Clair rivers to the south and east.
Royal Oak was not incorporated as a village until 1891, and as a city in 1921. It was named in 1819, during one of the surveying expeditions led by Territorial Governor Lewis Cass.
