Fort Massac (Massac County, Illinois)

Massac County · Illinois · French and Indian War, American Revolutionary War, Northwest Indian War

Quick BriefBuilt by the French in 1757 during the French and Indian War and originally called Fort de L'Ascension, the fort was renamed in 1759 to honor the French Colonial Affairs minister. Though the British anglicized the fort's name and briefly occupied it, they did not rebuild it, leaving it abandoned when Colonel George Rogers Clark led his "Long Knives" regiment into Illinois in 1778, enabling the capture of Kaskaskia and the entire Illinois Territory for Virginia and the United States. In 1794, President George Washington ordered the fort rebuilt, and it protected American military and commercial interests in the Ohio Valley for the next twenty years. The site became the first Illinois state park in 1908.

History & Significance

The French built Fort De L'Ascension on the site in 1757 during the French and Indian War, when France and Great Britain fought for ultimate control of central North America. Rebuilt in 1759–1760, the structure was renamed Massiac in honor of the French Minister of Colonial Affairs and endured one unsuccessful attack by Cherokee forces.

Following the war's end in 1763, the French abandoned the fort and a band of Chickasaws burned it to the ground. Though the British anglicized the name to "Massac," they neither rebuilt nor re-garrisoned the fort, an oversight that proved costly when Colonel George Rogers Clark arrived in 1778 with his regiment.

Clark captured Kaskaskia one hundred miles north without firing a shot, securing the entire Illinois Territory for the United States. President George Washington ordered the fort rebuilt in 1794, and it served for twenty years to protect American military and commercial interests in the Ohio Valley.

Vice President Aaron Burr and General James Wilkinson met at the fort in summer 1805. The fort was damaged by the New Madrid earthquakes of 1811–1812 but was rebuilt in time to play a minor role in the War of 1812 before being abandoned in 1814. In 1903, through efforts of the Daughters of the American Revolution, the state purchased 24 acres, and the fort was officially dedicated as Illinois's first state park on November 5, 1908.
