Major Pre-Revolutionary Conflicts Among Native People

While wars between the Indian people and settlers prior to the Revolution are certainly noteworthy and some even played an important role in setting the stage for the American Revolution, these wars were very different than the conflicts that would take place after the Revolution. Reading the Wikipedia summary of wars with the American Indians should help clarify this. See the question at the end of this article.

Bacon's Rebellion began as a conflict between settlers of the Jamestown area and the native people of the region. During its course it deteriorated even further to a broader conflict between the classes, with the Indian people ancillary to the conflict.

Beaver (Iroquois) Wars I (1535-1650) Indian against Indian
The history of this war chronicles the phenomenal rise of the Iroquois Confederacy during the "Beaver Wars" of the 17th century. In what were perhaps the greatest series of military victories in Native American history, the Five Nations of the Iroquois (the Mohawks, Oneidas, Onondagas, Cayugas, and Senecas) defeated, destroyed, and absorbed enemy tribes stretching over a vast area from eastern Canada to Virginia to Illinois--forever changing the cultural map of eastern North America. During this period, the Iroquois emerged as a dominant force that was both respected and dreaded by neighboring tribes and the European colonial powers alike. While the end result of these Iroquois wars was the famed Iroquois confederacy, the Beaver wars were actually waged over hunting grounds vital to a growing fur trade with Europeans. Most of the primary sources of information from this war come from Jesuit Priests who were living with the Iroquois.

The Pequot War (1634-1638)
Often said to be the first real war between settlers and the Indian people, this characterization is more ethnocentrism than fact. (-ed)

(Source: Wikipedia) The Pequot war was an armed conflict in 1634-1638 between an alliance of Massachusetts Bay and Plymouth colonies with Native American allies (the Narragansett and Mohegan tribes) against the Pequot tribe. The result was the elimination of the Pequot as a viable polity in what is present-day Southern New England.
Most of the Pequot people, warriors or otherwise, were killed by the colonists and their allies, or captured and sold into slavery in Bermuda. Other survivors were dispersed. It would take the Pequot more than three and a half centuries to regain political and economic power in their traditional homeland region along the Pequot (present-day Thames) and Mystic rivers in what is now southeastern Connecticut.

Beaver (Iroquois) Wars II (aka French and Indian Wars) (1650-1675)
Involved both Indian and French Settlers
The Beaver wars continue to foster the rise of the Iroquois Confederacy beginning with a series of victories won by the Iroquois over neighboring tribes following the defeat and collapse of their Huron enemies in 1650. Iroquois war parties fought wide-ranging campaigns against enemy tribes and Europeans alike in practically every state east of the Mississippi. In doing so, they destroyed or displaced dozens of tribes, many of which are known to history by their names alone.

King Phillips War <1675-1677> This bitter conflict, pitting the New England colonies against the Narraganset and Wampanoag tribes, was fought from 1675-1677. The colonial militias suffered severe reverses before finally conquering Philip with the help of the Mohegans and other Indian allies.

The French & Indian Wars <175(4)6-1763> (In Canada The Seven Years War) was actually a series of wars between the colonial powers battling over portions of the American and Canadian frontiers. Native peoples were recruited as combatants by both sides. Note the important role that this war played in fostering a climate for the American Revolution.

Dramatic Declines in Indian Populations After Colonization

Genocide or Democide?

Debate still rages about the specific reasons for a dramatic decline in the population of American Indian people, particularly those in the Northeast, following the establishment of European Colonial settlements.

Estimates of the decline in a period of only about 20-40 years in the early 1500's amount to as much as a 90%+ decline. Given the small number of settlements and the lack of conflict over territory at this earlier period, it is probably safe to assume that little of this decline can be attributed to outright conflict, and most historians concur with this.

The decline was precipitated by rapidly spreading diseases introduced purposefully or by virtue of simple accidental exposure among the tribes. Diseases like smallpox, influenza, bubonic plague and pneumonic plagues, spread like wildfire among Indian populations. There is evidence that such plagues were purposeful among Indians in the western US during the period of westward expansion of the American population, but it seems likely that most of the original decline of Northeast tribes were naturally occurring as a result of exposure of the Indian people to diseases that they had no natural immunities to.

Bi-directional infections: There is also evidence that some venereal diseases originated in the US and were carried back to Europe by explorers but this seems to be the only health related diseases carried from the American colonies to Western Europe.
