The first non-Native settlers in the Chicago region were primarily explorers aligned with the Jesuits, a religious order within the Catholic Church. The order was founded in 1540 and sought to evangelize and “save the souls” of non-Christians around the world through the establishment of missions. In the Great Lakes, the Jesuits who traveled throughout the region were primarily French. Jesuit expeditions throughout the region were ordered and approved by the Catholic Church, which was closely tied to the French government. The primary purpose of Jesuit expeditions was to establish missions and evangelize Native people, but that did not stop them from noticing the land’s natural resources and its potential for settlement, trade, and exploitation. The most famous Jesuit missionaries associated with Chicago are Father Jacques Marquette and Louis Jolliet, who traveled up the Illinois River and through the Chicago portage in 1673. Marquette returned to and camped at Chicago again in 1674 after becoming ill.
The vast majority of our written records from the late 17th century come from Jesuit materials, These accounts must be read with a careful eye, but they can also provide rich information about Native cultures and peoples. For example, this passage describes how Native people Marquette had previously encountered brought him food and supplies during his illness, including corn, pumpkins, meat, blueberries, and beaver skins, all of which were essential to his survival.
