What were the Anglo-Powhatan Wars?

The Anglo-Powhatan Wars were a series of battles fought between the Powhatan Native American tribe and English colonists of the Virginia Colony. Virginia historians believe the Powhatan tribe may have represented more than one tribe, similar to the Iroquois Federation in its structure and the breadth of the number of tribes represented.
The first war lasted five years, 1609–1614. The battles took place at the Jamestown Colony. The colonists were forced by drought to ask for the survival assistance of the local Indigenous tribes, creating a conflict over the use of the natural resources in the area with English settlers. The increasing tensions and conflicts resulted in a siege of sorts of the English fort by the Powhatan member tribes. The period is sometimes known as the "starving time," as the English were unable to leave their fort to search for food.
Before the English were forced to surrender the fort, reinforcements arrived from England. The soldiers relentlessly attacked the Native American tribes, exacting a significant toll on them. English soldiers burned villages and killed Natives, including women and children. In an attempt to end the conflict, the English settlers kidnapped and held Pocahontas, the daughter of the tribal leader of the Powhatan tribe, for ransom.
The second war began in 1622. It was prolonged by constant attack and retaliation by both sides until 1632. The first war ended in a marriage between John Rolfe and Pocahontas, which for a time resulted in a tense peace between the English and Powhatans. This period of the war was the result of the Powhatan wanting to take back control over lands ceded to the English as the English continued to press inward up the James River. In a coordinated series of attacks, Powhatan warriors were able to defeat the English at various strategic points. Historians believe these attacks resulted in the death of about one-third of the English settlers, and rather than press forward, the Powhatan decided to stop their attacks, believing the English would no longer attempt to colonize inland.
This turned out not to be the case, as the English regrouped and for the next ten years continually attacked the food supplies of the Native tribes. An uneasy peace began to take shape as the Powhatan tribes recognized they were only postponing the deeper incursion of the land by English settlers. English soldiers proved to be relentless and ruthless, leaving the Native tribes decimated from war and not being able to protect their way of life from the waves of settlers.
The third and final war occurred in 1644 and lasted about two years. The Powhatan, in a last effort to restore tribal rule over disputed lands, attacked the outlying tobacco farms not close to the principal forts and settlements. The English mustered a significant amount of military force, essentially quelling the continued attacks and ending the war. Powhatan warriors captured during the battles were sold as slaves, and tribal leaders were executed. A peace treaty was signed, ending the two-year conflict. The agreement required Native tribes to be relocated to areas a considerable distance from English settlements and is viewed by historians as the first forced relocation of tribes, establishing a template for more aggressive tribal relocations in the future.
