In 1701, French explorer and army officer Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit or "Fort Pontchartrain on-the-Strait" on the strait, known as the Detroit River, between lakes Saint Clair and Erie. Cadillac had convinced King Louis XIV's chief minister, Louis Phélypeaux, Comte de Pontchartrain, that a permanent community there would strengthen French control over the upper Great Lakes and discourage British aspirations.
