During the 16th century, European fishermen, whalers, traders, adventurers, and explorers visited the eastern seaboard of North America and established a lucrative fur trade by the early 1600s. While fishermen and whalers had generally co-operated with First Peoples in exchanging goods, permanent European settlement and involvement in the fur trade with Hurons and Algonkians soon led the French to join these nations in their war with the Iroquois Confederacy.
