# Fortifications of New Netherland

New Netherland, or Nieuw-Nederland in Dutch, was the 17th century colony of the Republic of the Seven United Netherlands on the northeastern coast of North America. The claimed territory included southern Cape Cod to parts of the Delmarva Peninsula. Settled areas are now part of the Mid-Atlantic states of New York, New Jersey, Connecticut, Delaware and Pennsylvania. Its capital, New Amsterdam, was located at the southern tip of the island of Manhattan on Upper New York Bay.
Explored in 1609 by Henry Hudson while sailing on an expedition for the Dutch East India Company, the region was later surveyed, charted and given its name in 1614. The Dutch named the three main rivers of the province the Zuyd Rivier or "South River", the Noort Rivier or "North River", and the Versche Rivier or "Fresh River", and intended to use them to gain access to the interior, to the Native Americans and to the lucrative fur trade.
International law required not only discovery and a charter, but also the founding of forts and villages to confirm a territorial claim. Large-scale settlements were rejected by the Dutch in favor of the factorijen, a trading post with soldiers and a small group of settlers. During the first decade the New Netherland Company built Fort Nassau in Mahican/Mohawk territory on the North River. Among the places it is believed factorijen were set up are Schenectady, Schoharie, Esopus, Manhattan, Communipaw, Roodenburg, and Ninigret.
The Dutch West India Company (WIC) was granted a charter by the Republic of the Seven United Netherlands on June 3, 1621, forming a joint venture to exploit trade in New Netherland. The first settlers landed on Noten Island in 1624 and began the fortification and population of the colony. The names Fort Nassau and Fort Orange were used by the Dutch in the 17th century for several fortifications around the world in honor of the House of Orange-Nassau.
New Sweden was first settled in 1637 on territory claimed by the Dutch Republic, which was unable to prevent the incursion and did not officially recognize the colony. It was brought under Dutch control in a military expedition led by Director-General of New Netherland Peter Stuyvesant in 1655. In that year the government enacted regulations requiring settlers throughout the province to construct stockades to which they could withdraw if attacked, the most extensive being at Wiltwyck.
