The history of New York begins around 10,000 B.C. when the first people arrived. By 1100 A.D. two main cultures had become dominant as the Iroquoian and Algonquian developed. European discovery of New York was led by the Italian Giovanni da Verrazzano in 1524 followed by the first land claim in 1609 by the Dutch. As part of New Netherland, the colony was important in the fur trade and eventually became an agricultural resource thanks to the patroon system. In 1626 the Dutch thought they had bought the island of Manhattan from Native Americans. In 1664, England renamed the colony New York, after the Duke of York and Albany, brother of King Charles II. New York City gained prominence in the 18th century as a major trading port in the Thirteen Colonies.
