Fort Mackinac (Mackinac Island, Michigan)

Mackinac Island · Michigan · American Revolutionary War, War of 1812

Quick BriefLieutenant Governor Patrick Sinclair constructed Fort Mackinac in 1780–1781 as a limestone structure on 150-foot bluffs above the Straits of Mackinac. The British built it to control the strategic Straits of Mackinac between Lake Michigan and Lake Huron, and by extension the fur trade on the Great Lakes. The fort later became the scene of two strategic battles for control of the Great Lakes during the War of 1812. Closed in 1895, the fort has been adapted as a museum on the grounds of Mackinac Island State Park.

History & Significance

After the Treaty of Paris (1763), the British occupied the French fort but considered the wooden structure too difficult to defend. Lieutenant Governor Patrick Sinclair constructed a new limestone fort in 1780–1781 on the 150-foot limestone bluffs of Mackinac Island.

The British held the outpost throughout the American Revolutionary War. Despite the Treaty of Paris (1783), the British did not officially relinquish the fort to the United States until the Jay Treaty was ratified in 1796.

The fort became pivotal during the War of 1812. On the morning of July 17, 1812, a combined British and Native American force of seventy war canoes and ten bateaux under British Captain Charles Roberts attacked Fort Mackinac.

Fearing a massacre by the Natives, Hanks capitulated without a fight. British control of Fort Mackinac was not seriously challenged until 1814 when a large American force was dispatched to retake control, but the American force was defeated in the Battle of Mackinac Island.

Following the Treaty of Ghent, American forces reoccupied Fort Mackinac in July 1815. During most of the 19th century, it served as an outpost of the United States Army. In 1895, Congress transferred the fort and park to the State of Michigan, which created Mackinac Island State Park, the first state park in Michigan.
