The hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent (about , the equivalent of just under per side) and named it Fort Pontchartrain. Cadillac's wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of the first European women to settle in what was considered the wilderness of Michigan. The town quickly became a major fur-trading and shipping post. The Église de Saint-Anne (Catholic Church of Saint Anne) was founded the same year. While the original building does not survive, the congregation remains active. Cadillac later departed to serve as the French governor of Louisiana from 1710 to 1716. French attempts to consolidate the fur trade led to the Fox Wars, in which the Meskwaki (Fox) and their allies fought the French and their Native allies.
