Final answer:
The primary cause of Nathaniel Bacon-led rebellion was the vast differences in land ownership between the choice tidewater land and western interior lands in the Virginia colony.
Step-by-step explanation:
The Nathaniel Bacon-led rebellion in Virginia was primarily fueled by stark disparities in land ownership between the coveted tidewater areas and the less desirable western interior lands. Wealthy landowners monopolized the prime locations, leaving smaller farmers, aspiring landowners, and marginalized groups like landless men, indentured servants, and slaves with limited options. This unequal distribution of land resources created a discontented class that was dissatisfied with the lack of support and protection from Governor Berkeley.
In response to these grievances, Nathaniel Bacon emerged as the leader of the disenchanted group, articulating their frustrations and echoing their concerns about the governor's perceived failure to safeguard the colonists, especially against Native American threats. The Bacon-led rebellion thus symbolized a socio-economic uprising, highlighting issues of land inequality and a perceived neglect by the colonial government, with Bacon rallying a diverse coalition of discontented individuals against the existing power structures.
