The Erie people (also Erieehronon, Eriechronon, Riquéronon, Erielhonan, Eriez, Nation du Chat) were a Native American people historically living on the south shore of Lake Erie. An Iroquoian group, they lived in what is now western New York, northwestern Pennsylvania, and northern Ohio before 1658.  Their nation was decimated in the mid-17th century by five years of prolonged warfare with the powerful neighboring Iroquois for helping the Huron in the Beaver Wars for control of the fur trade." 
Their villages were burned as a lesson to those who dared oppose the Iroquois. This destroyed their stored maize and other foods, added to their loss of life, and threatened their future, as they had no way to survive the winter. The attacks likely forced their emigration. The Iroquois League was known for adopting captives and refugees into their tribes. The surviving Erie are believed to have been largely absorbed by other Iroquoian tribes, particularly families of the Seneca, the westernmost of the Five Nations. Susquehannock families may also have adopted some Erie, as the tribes had shared the hunting grounds of the Allegheny Plateau and Amerindian paths that passed through the gaps of the Allegheny. The members of remnant tribes living among the Iroquois gradually assimilated to the majority cultures, losing their independent tribal identities. 
The Erie were also called the Chat ("Cat" in French) or "Long Tail" (referring, possibly, to the raccoon tails worn on clothing or the Eastern Panther which played a role in Erie cosmology). Like all the Iroquoian stock, they lived in multi-family long houses in villages enclosed in palisades. These defensive works often encompassed their fields for crops. They cultivated the "Three Sisters": varieties of corn, beans, and squash, during the warm season. In winter, tribal members lived off the stored crops and animals taken in hunts.
While indigenous peoples lived along the Great Lakes for thousands of years in succeeding cultures, historic tribes known at the time of European encounter began to coalesce by the 15th and 16th centuries. The Erie were among the several Iroquoian peoples sharing a similar culture, tribal organization, and speaking an Iroquoian language which emerged around the Great Lakes, but with elements that may have originated in the south. [a] Traditional rivalries and habitual competition among Amerindian tribes for resources (especially fire arms) and power was escalated by the lucrative returns of the fur trade with French and Dutch colonists beginning settlements in the greater area before 1611. Violence to control the fur-bearing territories, the beginnings of the long-running Beaver Wars, began early in the 17th century [b] so the normal peace and trading activity decreased between the tribes, who had responded to demand for beaver and other furs by over-hunting some areas.
The Erie encroached on territory which other tribes considered theirs.  During 1651,  they'd angered their eastern neighbors, the Iroquois League, by accepting Huron refugees from villages which had been destroyed by the Iroquois. Though reported as using poison-tipped arrows ( Jesuit Relations 41:43, 1655–58 chap. XI), the Erie were disadvantaged in armed conflict with the Iroquois because they had few firearms.  [c] By the mid-1650s, the Erie became a broken tribe— beginning in 1653  the Erie launched a preemptive attack on western tribes of the Iroquois, and did well in the first year of a five-year war. 
Consequently, in 1654 the whole Iroquois Confederacy went to war against the Erie and neighboring tribes such as the Neutral people along the northern shores of Lake Erie and across the Niagara River, the Tabacco people between the Erie and Iroquois, neighbors to all three groups. As a result, over five years of war they destroyed the Erie confederacy, the Neutrals, the Tobacco, with the tribes surviving in remnants. Dispersed groups survived a few more decades before being absorbed into the Iroquois, especially the westernmost Seneca nation.
Anthropologist Marvin T. Smith ( 1986:131–32) theorized that some Erie fled to Virginia and then South Carolina, where they became known as the Westo. Some were said to flee to Canada. Members of other tribes claimed later to be descended from refugees of this defunct culture, who intermarried with other peoples. Among those are members of the Seneca people in Oklahoma and Kansas.
Because the Erie were located further from the coastal areas of early European exploration, they had little direct contact with Europeans. Only the Dutch fur traders from Fort Orange (now Albany, New York) and Jesuit missionaries in Canada referred to them in historic records. The Jesuits learned more about them during the Beaver Wars, but most of what they learned, aside from a single in-person encounter, was learned from the Huron who suffered much reduction before the Erie did.  What little is known about them has been derived from oral history of other Native American tribes, archaeology, and comparisons with other Iroquoian peoples.
- In Virginia, visiting Susquehannocks were described by an admiring Captain John Smith. Further, Tuscarora and Cherokee lived in the south from before Jamestown was founded, and the powerful Susquehanna had a lock on the Susquehanna basin into the upper Chesapeake Bay shores, probably into the northern Shenandoah Valley. The editors of New American Heritage state the various confederacies of Iroquoian tribes migrated from south to the Great Lakes regions and in between well before pre-Columbian times. Conversely, others such as the editors of the 1911 Encyclopædia Britannica suggest the tribes originated in what became Algonkian territories along the Saint Lawrence and moved west and south when the Algonquian tribes moved north up the coast and spread west. By the time of European encounter, Algonquian and Iroquoian tribes were competitive, although they were known to conduct trading and spent most years in uneasy peace. Separation between tribes living in wilderness ensured contacts were mainly small affairs before the use fire arms tipped the balance of warfare to enhance the killing ability of a people who could not out run a bullet, a limitation which existed before guns and the ability to kill at range.
- Beaver Wars are usually blamed upon the Iroquois who were believed to have a joint population dwarfed by surrounding tribes.
- If the Erie tribe had used poison on their arrows, they would have been the only tribe in North America to do so.

- According to The American Heritage Book of Indians the Susquehannock were poised to wipe out the Iroquois after administering severe drubbings into 1668, only to be laid low by multi-year disease epidemics in 1669-1671. By 1672-1673 they were beset on all sides and, like the Erie, went extinct as a tribe because of their high mortality rate. Their small percentage of survivors had to disperse among kindred tribes. The Iroquois adopted their remnants under the terms of a formal treaty in 1678. Some of the Susquehannock fleeing during 1676 triggered Bacon's Rebellion in the south.
