This chapter examines the Dutch mercantile colony located on Manhattan Island and in the Hudson Valley up to Albany, English settlements on Long Island, and a small initially Swedish colony along the lower Delaware River. Its main focus is on the legal system created by the Dutch. It was a sophisticated, centralized, civil law system that reposed ultimate decisional power in the hands of a director-general directing the government from Manhattan Island and in the hands of his superiors in the Netherlands. The English settlements on Long Island, on the other hand, copied the localized power structures of New England, although the Long Islanders operated more informally and less learnedly. Dispute resolution in the tiny colony along the Delaware was unlearned and totally informal.
