===Native peoples===
Prior to the arrival of Europeans in the early 17th century, the [[Lenape]], an [[Native Americans in the United States|Indian tribe]] also known as the Delaware Indians, lived in the village of [[Treaty of Shackamaxon|Shackamaxon]] in present-day Philadelphia and the surrounding area.<ref name=josephy>Josephy 188–189</ref> The Lenape historically lived along the [[Delaware River]] [[Drainage basin|watershed]], western [[Long Island]], and the [[Hudson Valley|Lower Hudson Valley]].{{efn|1= Description of the Lenape peoples (Delaware nations) historic territories inside the [[divides]] of the frequently mountainous [[landforms]] flanking the [[Delaware River]]'s [[drainage basin]]. These terrains encompass from South to North and then counter-clockwise:

| portions of Western Connecticut up to the latitude of the Massachusetts corner of today's boundaries—making the eastern bounds of their influence, thence their region extended:
| westerly past the region around [[Albany, New York]] to the [[Susquehanna River]] side of the [[Catskills]], then
| southerly through the eastern [[Pocono Mountains|Poconos]] outside the rival [[Susquehannock]] lands past [[Province of Pennsylvania|Eastern Pennsylvania]] then southerly past the site of [[History of Philadelphia|Colonial Philadelphia]] past the west bank mouth of the Delaware and extending south from that point along a stretch of sea coast in northern colonial [[Delaware]].

The [[Susquehanna River|Susquehanna]]-[[Delaware River]] system's [[Drainage basin|watershed]] divided the frequently contested hunting grounds between the rival [[Susquehannock]]  people and Lenape peoples, and the Catskills and Berkshires played a similar boundary role in the northern regions of their original colonial era range.}} Most Lenape were pushed out of the region during the 18th century as the original [[Thirteen colonies]] expanded, which was further exacerbated by losses from intertribal conflicts.<ref name=josephy/> Lenape communities were also weakened by newly introduced diseases, mainly [[smallpox]], and conflicts with Europeans. The [[Iroquois]] occasionally fought the Lenape. Surviving Lenape moved west into the upper [[Ohio River]] basin. Following the [[American Revolutionary War]] and the subsequent establishment of the United States, the Lenape began moving further west. In the 1860s, the [[Federal government of the United States|U.S. federal government]] sent most remaining Lenape in the [[East Coast of the United States|eastern United States]] to the [[Indian Territory]] in present-day [[Oklahoma]] and surrounding territories as part of the [[Indian removal]] policy.
