Royal Oak was incorporated as a village in 1891, and as a city in 1921. The name originated in 1819, during one of Territorial Governor Lewis Cass' surveying expeditions. A large oak tree located near the present-day intersection of Crooks, Rochester, and Main reminded Cass of the Royal Oak which King Charles II of England hid in to escape capture by the Roundheads after the Battle of Worcester.
