Final answer:
Bacon's Rebellion was caused by economic disparity between planters, high taxes exacerbated by falling tobacco prices, and discontent with Governor Berkeley's policies towards Native Americans and frontier defense.
Step-by-step explanation:
The primary causes of Bacon's Rebellion can be identified as economic disparity, high taxes, and Governor Berkeley's policies. Firstly, resentment was building against Governor Berkeley, who favored the wealthy, which created an economic rift between the larger planters and the smaller planters and landless tenants. These commoners ended up with the worst land while also shouldering high taxes to support the governor and the burgesses. Secondly, these high taxes became increasingly burdensome as the price of tobacco plummeted due to the Navigation Acts and trade wars with the Dutch. Lastly, Berkeley's refusal to allow retaliation against Native American attacks, along with his defense policies during the Susquehannock War, which potentially meant further tax increases, led the colonists to rally behind Bacon in rebellion against the colonial government.
