New Netherland

New Netherland (Dutch: Nieuw Nederland) was a 17th-century colonial province of the Dutch Republic located on the east coast of what is now the United States of America. The claimed territories extended from the Delmarva Peninsula to Cape Cod. Settlements were established in what became the states of New York, New Jersey, Delaware, and Connecticut, with small outposts in Pennsylvania and Rhode Island.

The colony was originally conceived by the Dutch West India Company (GWC) in 1621 to capitalize on the North American fur trade. Settlement initially stalled because of policy mismanagement by the GWC, and conflicts with Native Americans. The settlement of New Sweden by the Swedish South Company encroached on its southern flank, while its eastern border was redrawn to accommodate an expanding New England Confederation.

The colony experienced dramatic growth during the 1650s, and became a major center for trade across the North Atlantic. The Dutch conquered New Sweden in 1655, but during the Second Anglo-Dutch War, surrendered New Netherland to the English following the capture of New Amsterdam. In 1673, the Dutch retook the colony but relinquished it under the Treaty of Westminster (1674) that ended the Third Anglo-Dutch War.

The inhabitants of New Netherland (New Netherlanders) were European colonists, Native Americans, and Africans imported as slave laborers. Not including Native Americans, the colonial population, many of whom were not of Dutch descent, was 1,500 to 2,000 in 1650, and 8,000 to 9,000 at the time of transfer to England in 1674.
