The European settlers in Virginia built their society also on the effective suppression of the local Indians. For two years in the 1610s, Sir Thomas Dale, De La Warr's successor as governor, commanded unrelenting assaults againt the Powhatan Indians, led by (and named for) their formidable chief, Powhatan. In the process, Dale kidnapped Powhatan's young daughter Pocahontas. Several years earlier, Pocahontas had played a role in mediating differences between her people and the Europeans. But now, Powhatan refused to ransom her. By the time of Pocahontas's marriage with John Rolfe, Powhatan had ceased his attacks on the English in the face of overwhelming odds. But after his death several years later, his brother, Opechancanough, began secretly to plan the elimination of the English intruders. On a March morning in 1622, tribesmen called on the white settlements as if to offer goods for sale; then they suddenly attacked. Not until 347 whites of both sexes and all ages (including John Rolfe) lay dead did the Indian warriors finally retreat. And not until over twenty years later were the Powhatans finally defeated.
