Samuel de Champlain, the founder of New France, commissioned Jean Nicolet to form a peaceful alliance with Native Americans in the western areas, whose unrest interfered with French fur trade, and to search for a shorter trade route to China through Canada. Nicolet and others had learned from other First Nations of the Ho-Chunk (Winnebago) people, who identified as "People of the Sea", and believed they must reside on or near the Pacific Ocean. Champlain had also heard about natural resources in the area, including fertile soil, forests, and animals.
