The Lenape (English:  or ), also called the Leni Lenape, Lenni Lenape and Delaware people, are an indigenous people of the Northeastern Woodlands, who live in Canada and the United States. Their historical territory included present-day New Jersey and eastern Pennsylvania along the Delaware River watershed, New York City, western Long Island, and the Lower Hudson Valley. Today, Lenape people belong to the Delaware Nation and Delaware Tribe of Indians in Oklahoma, the Stockbridge-Munsee Community in Wisconsin, and the Munsee-Delaware Nation, Moravian of the Thames First Nation, and Delaware of Six Nations in Ontario. The Lenape have a matrilineal clan system and historically were matrilocal.
New Amsterdam was founded in 1624 by the Dutch in what would later become New York City. Dutch settlers also founded a colony at present-day Lewes, Delaware on June 3, 1631 and named it Zwaanendael (Swan Valley). The colony had a short life, as in 1632 a local band of Lenape killed the 32 Dutch settlers after a misunderstanding escalated over Lenape defacement of the insignia of the Dutch West India Company. In 1634, the Iroquoian-speaking Susquehannock went to war with the Lenape over access to trade with the Dutch at New Amsterdam. They defeated the Lenape, and some scholars believe that the Lenape may have become tributaries to the Susquehannock. After the warfare, the Lenape referred to the Susquehannock as "uncles." The Iroquois added the Lenape to the Covenant Chain in 1676; the Lenape were tributary to the Five Nations (later Six) until 1753, shortly before the outbreak of the French and Indian War (a part of the Seven Years' War in Europe).  The Lenape's quick adoption of trade goods, and their need to trap furs to meet high European demand, resulted in their disastrous over-harvesting of the beaver population in the lower Hudson Valley. With the fur sources exhausted, the Dutch shifted their operations to present-day upstate New York. The Lenape who produced wampum in the vicinity of Manhattan Island temporarily forestalled the negative effects of the decline in trade. Lenape population fell sharply during this period, due to high fatalities from epidemics of infectious diseases carried by Europeans, such as measles and smallpox, to which they had no natural immunity, as the diseases had arisen on the Asian continent and moved west into Europe, where they had become endemic in the cities.  The Lenape had a culture in which the clan and family controlled property. Europeans often tried to contract for land with the tribal chiefs, confusing their culture with that of neighboring tribes such as the Iroquois. The Lenape would petition for grievances on the basis that not all their families had been recognized in the transaction (not that they wanted to "share" the land). After the Dutch arrival in the 1620s, the Lenape were successful in restricting Dutch settlement until the 1660s to Pavonia in present-day Jersey City along the Hudson. The Dutch finally established a garrison at Bergen, which allowed settlement west of the Hudson within the province of New Netherland. This land was purchased from the Lenape after the fact.  In 1682, William Penn and Quaker colonists created the English colony of Pennsylvania beginning at the lower Delaware River. A peace treaty was negotiated between the newly arriving English and Lenape at what is now known as Penn Treaty Park. In the decades immediately following, some 20,000 new colonists arrived in the region, putting pressure on Lenape settlements and hunting grounds. Although Penn endeavored to live peaceably with the Lenape and to create a colony that would do the same, he also expected his authority and that of the colonial government to take precedence. His new colony effectively displaced many Lenape and forced others to adapt to new cultural demands. Penn gained a reputation for benevolence and tolerance, but his efforts resulted in more effective colonization of the ancestral Lenape homeland than previous ones. CANNOTANSWER
17th century
At the time of sustained European contact in the 16th centuries and 17th centuries, the Lenape were a powerful Native American nation who inhabited a region on the mid-Atlantic coast spanning the latitudes of southern Massachusetts to the southern extent of Delaware in what anthropologists call the Northeastern Woodlands. Although never politically unified, the confederation of the Delaware roughly encompassed the area around and between the Delaware and lower Hudson rivers, and included the western part of Long Island in present-day New York. Some of their place names, such as Manhattan ("the island of many hills"), Raritan, and Tappan were adopted by Dutch and English colonists to identify the Lenape people that lived there. Based on the historical record of the mid-17th century, it has been estimated that most Lenape polities consisted of several hundred people but it is conceivable that some had been considerably larger prior to close contact, given the wars between the Susquehannocks and the Iroquois, both of whom were armed by the Dutch fur traders, while the Lenape were at odds with the Dutch and so lost that particular arms race.  During the Beaver Wars in the first half of the 17th century, European colonists were careful to keep firearms from the coastally located Delaware, while rival Iroquoian peoples such as the Susquehannocks and Confederation of the Iroquois became comparatively well armed. Subsequently, the Lenape became subjugated and made tributary to first the Susquehannocks, then the Iroquois, even needing their rivals' (superiors') agreement to initiate treaties such as land sales. Like most tribes, Lenape communities were weakened by newly introduced diseases originating in Europe, mainly smallpox but also cholera, influenza and dysentery, and recurrent violent racial conflict with Europeans. Iroquoian peoples occasionally fought the Lenape. As the 18th century progressed, many surviving Lenape moved west--into the (relatively empty) upper Ohio River basin.  Smallpox devastated Native American communities even located far from European settlements by the 1640s. The Lenape and Susquehannocks fought a war in the middle of the 17th century that left the Delaware a tributary state even as the Susquehannocks had defeated the Province of Maryland between 1642-50s.
