Jacques Marquette and Louis Jolliet claimed several significant discoveries during their exploration in the 17th century. They are best known for their expedition to the Mississippi River, where they mapped portions of the river and its tributaries, providing vital information about the geography and Native American tribes in the region. Their journey helped establish French claims to the territory and laid the groundwork for future exploration and colonization in North America. Jolliet's detailed accounts contributed to European knowledge of the central United States.
