The Mississippi River Valley received its first significant European mapping in 1673, when Jacques Marquette collaborated with explorer Louis Jolliet. A member of the Society of Jesus, Marquette spent his career navigating the Great Lakes region and establishing mission outposts, bridging the gap between his religious duties as a Catholic priest and the practical demands of frontier exploration.
Ecclesiastical Education and Arrival
Born in Laon, Kingdom of France, in 1637, Marquette entered the Jesuit College of Reims at age nine. He joined the Society of Jesus at 17, refining his philosophy studies at Pont-à-Mousson until 1659. Following his ordination in Toul on March 7, 1666, he travelled to Quebec, arriving that September to begin his work as a missionary.

His initial training occurred at the mission of Saint Michel at Sillery, where he learned the customs and languages of the Algonquin, Abenaki, and Iroquois. During a subsequent two-year tenure at Trois-Rivières, he achieved fluency in six dialects. In 1668, he moved into the Great Lakes region, founding the Sault Ste. Marie mission alongside Claude-Jean Allouez and Louis Broeme.
Regional Transitions and Migrations
In 1669, Marquette replaced Allouez at the La Pointe du Saint Esprit mission after a difficult 500-mile journey across Lake Superior. Tensions with the Lakota eventually forced a relocation; Marquette facilitated the migration of his followers to a new site, ultimately establishing the St. Ignace Mission on the Michigan mainland in the autumn of 1671.
Mississippi River Expedition
Granted leave from his missionary duties in 1673, Marquette accompanied Louis Jolliet on an expedition departing St. Ignace on May 17. Utilizing two canoes, the party travelled through Lake Huron and Lake Michigan into Green Bay. They continued up the Fox River, documenting encounters with the Menominee, Miami, Mascouten, and Kickapoo tribes before reaching the Mississippi.
