What drives Royal Oak’s History grade
On its age, its old homes and the National Register, Royal Oak is more historic than 78% of U.S. towns, #142 of 701 in Michigan. All 3 inputs are above most U.S. towns; its age ranks highest and its National Register listings lowest.
A−
HistoryA character grade: shown, never part of Royal Oak’s overall grade.
Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Royal Oak’s 0.3 sits near the middle of its state (64% of Michigan towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A−. The pre-1940 share (±1.4 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1891.

What stands out about Royal Oak’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Royal Oak was named in 1819, during one of the surveying expeditions led by Territorial Governor Lewis Cass. A large oak tree at this small settlement reminded Cass of the story of the Royal Oak, where King Charles II of England, Scotland and Ireland hid to escape capture by the Roundheads after the Battle of Worcester, so he chose that name for the settlement.
Royal Oak was not incorporated as a village until 1891. It was reincorporated a city in 1921.
Royal Oak developed as a suburb of Detroit in the early 20th century, following Detroit's booming growth as a result of industrialization and its auto industry.
