Dutch trade in the New York area led to the establishment of trade posts as early as 1613. Permanent settlers arrived in 1617 at what is now Albany, New York. New Amsterdam was settled in 1625. In 1629, Dutch officials tried to expand the northern colony through a plan that promised "Liberties and Exemptions" to anyone who would ship fifty colonists to America at his own expense. Anyone who did so would be allowed to buy a stretch of land along the Hudson River from the Dutch West India Company of about twelve miles, extending as far inland as the owner wanted. The landowners were called patroons and had complete jurisdiction over their domains as well as extensive trading privileges. They also received these rights in perpetuity. That was a form of feudalism, which had vanished in the Dutch Republic but was introduced in North America. The Patroonships were not a success; by 1635, the Dutch West India Company had bought back four of the five patroonships originally registered in Amsterdam.
