Final answer:
Nathaniel Bacon contended that Governor William Berkeley had established a monopoly over the lucrative Indian trade, favoring wealthy colonists, which was among the central grievances leading to Bacon's Rebellion in 1676.
Step-by-step explanation:
One of Nathaniel Bacon's grievances during Bacon's Rebellion was that Governor William Berkeley had what Bacon perceived as a monopoly over the Indian trade. Berkeley had used his power to grant the best public office, best public land, and nearly exclusive access to the Indian trade to the wealthiest colonists. This left smaller planters and landless tenants at a significant disadvantage.
They received poor land, were subject to high taxes, which became increasingly difficult to afford due to the falling price of tobacco, and felt neglected when it came to colonial protection from Native American tribes. Bacon's Rebellion in 1676 was a direct result of this growing discontent among the more impoverished colonists, who saw Berkeley's policies as favoring the established elite at their expense.
