Detroit was founded by Europeans in 1701 when the colonial French established a fort here as a center for trading. The European population numbered 100 French soldiers, farmers and merchants. The first women arrived in September. The fort attracted Native Americans of the region, and bands of various tribes settled nearby, including the Huron. They soon far outnumbered the French.

Detroit developed as the most important French city between Montreal and New Orleans, two major areas of colonial settlement.

Its European population was 800 people in 1765, shortly after France ceded its territory east of the Mississippi River to Great Britain after being defeated in the Seven Years’ War. By that time, most or all of the Native Americans had moved from the area.

By 1773, the population of Detroit was 1,400.

By 1778, its population was 2,144 and it was the third largest city in the British Province of Quebec. At this time, the British considered it part of Quebec rather than the Thirteen Colonies.

According to a census conducted in 1750, more than a quarter of the 96 French families in Detroit owned Indian slaves, who constituted about 7% of the enumerated population.

Detroit took another census under the orders of the British commandant, Henry Hamilton, on April 26, 1778.  According to that tally, Detroit’s population stood at 2,144 people, excluding military personnel and prisoners.
