Berkeley finally did face a rebellion in 1676. Indians had begun attacking encroaching settlers as they expanded to the north and west. Serious fighting broke out when settlers responded to violence with a counter-attack against the wrong tribe, which further extended the violence. Berkeley did not assist the settlers in their fight. Many settlers and historians believe Berkeley's refusal to fight the Indians stemmed from his investments in the fur trade. Large scale fighting would have cut off the Indian suppliers Berkeley's investment relied on. Nathaniel Bacon organized his own militia of settlers who retaliated against the Indians. Bacon became very popular as the primary opponent of Berkeley, not only on the issue of Indians, but on other issues as well. Berkeley condemned Bacon as a rebel, but pardoned him after Bacon won a seat in the House of Burgesses and accepted it peacefully. After a lack of reform, Bacon rebelled outright, captured Jamestown, and took control of the colony for several months. The incident became known as Bacon's Rebellion. Berkeley returned himself to power with the help of the English militia. Bacon burned Jamestown before abandoning it and continued his rebellion, but died of disease. Berkeley severely crushed the remaining rebels.
