Background: The Powhatan People (sometimes Powhatans) (also spelled Powatan) are an Indigenous group traditionally from Virginia. In some instances, The Powhatan, may refer to one of the leaders of the people. This is most commonly the case in historical writings by the English. The Powhatans have also been known as Virginia Algonquians, as the Powhatan language is an eastern-Algonquian language also known as Virginia Algonquian.
Context: In November 1609, Captain John Ratcliffe was invited to Orapakes, Powhatan's new capital. After he had sailed up the Pamunkey River to trade there, a fight broke out between the colonists and the Powhatan. All of the English ashore were killed, including Ratcliffe, who was tortured by the women of the tribe. Those aboard the pinnace escaped and told the tale at Jamestown.  During that next year, the tribe attacked and killed many Jamestown residents. The residents fought back, but only killed twenty. However, arrival at Jamestown of a new Governor, Thomas West, 3rd Baron De La Warr, (Lord Delaware) in June 1610 signalled the beginning of the First Anglo-Powhatan War. A brief period of peace came only after the capture of Pocahontas, her baptism, and her marriage to tobacco planter John Rolfe in 1614. Within a few years both Powhatan and Pocahontas were dead. Powhatan died in Virginia, but Pocahontas died while in England. Meanwhile, the English settlers continued to encroach on Powhatan territory.  After Wahunsunacawh's death, his younger brother, Opitchapam, briefly became chief, followed by their younger brother Opechancanough. In 1622 (Indian massacre of 1622) and 1644 he attacked the English to force them from Powhatan territories. Both these attempts were met with strong reprisals from the English, ultimately resulting in the near destruction of the tribe. The Second Anglo-Powhatan War that followed the 1644 incident ended in 1646, after Royal Governor of Virginia William Berkeley's forces captured Opechancanough, thought to be between 90 and 100 years old. While a prisoner, Opechancanough was killed, shot in the back by a soldier assigned to guard him. He was succeeded as Weroance by Necotowance, and later by Totopotomoi and by his daughter Cockacoeske.  The Treaty of 1646 marked the effective dissolution of the united confederacy, as white colonists were granted an exclusive enclave between the York and Blackwater Rivers. This physically separated the Nansemonds, Weyanokes and Appomattox, who retreated southward, from the other Powhatan tribes then occupying the Middle Peninsula and Northern Neck. While the southern frontier demarcated in 1646 was respected for the remainder of the 17th century, the House of Burgesses lifted the northern one on September 1, 1649. Waves of new immigrants quickly flooded the peninsular region, then known as Chickacoan, and restricted the dwindling tribes to lesser tracts of land that became some of the earliest Indian reservations.  In 1665, the House of Burgesses passed stringent laws requiring the Powhatan to accept chiefs appointed by the governor. After the Treaty of Albany in 1684, the Powhatan Confederacy all but vanished.
