Mackinaw City's first European settlement came in 1715 when the French built Fort Michilimackinac. They lost it to the British during the Seven Years' War, and the British abandoned the fort in 1783, after the American Revolutionary War resulted in independence of its Thirteen Colonies. The site of the fort in present-day Mackinaw City is a National Historic Landmark and is now preserved as an open-air historical museum. As with the forts at other settlements of the era and region such as Detroit, Michilimackinac was a fairly small post. It housed French civilians inside the fort, and allowed them to garden, hunt, and fish outside the walls. It was a trading post for the fur trade.
