Meanwhile, the English continued to expand along the James riverfront. The aged Powhatan's final years have been called "ineffectual" (Rountree 1990). Opchanacanough became the greater Native power in the region. Upon the death of Wahunsunacock in 1618, his next younger brother Opitchapam officially became paramount chief. However, Opchanacanough, the youngest brother, had achieved the greatest power and effectively became the Powhatan. By initiating the Indian Massacre of 1622, and attacks in 1644, he attempted to force the English from Virginia. These attempts met with strong reprisals from the English, ultimately resulting in the near destruction of the tribe.
