Nieuw-Nederland, or New Netherland, was the seventeenth-century colonial province of the Republic of the Seven United Netherlands on northeastern coast of North America. The claimed territory were the lands from the Delmarva Peninsula to southern Cape Cod. Settled areas are now part of the northeastern states of Delaware, New Jersey, New York, and southwestern Connecticut. There were small outposts in Pennsylvania and Rhode Island. Its capital, New Amsterdam, was located at the southern tip of the island of Manhattan on the Upper New York Bay. The most developed part of the province roughly corresponds to today's Tri-State area (New Jersey, New York, and Connecticut).
