His maps expanded European knowledge of the region, and were used as the basis for new European maps of North America, according to Hermann and Pearce.
Champlain made seven trips to forge fur-trade alliances, help priests establish missions and assist in founding the New France Colony. But his most important, all-consuming charge from 1608-16, finding the Northwest Passage to open European trade with China, was never realized.
He wanted to go to James Bay, the lower section of Canada's Hudson Bay, for that purpose.
Pearce said the tribes promised again and again to take Champlain to the James Bay in exchange for continued trade and his military alliance against the Iroquois, but they never did.
Champlain ended his search for James Bay after eight years and died in Quebec in 1635.
