Which was a factor that led to Bacon's Rebellion

Bacon's Rebellion was an armed rebellion organized in 1676. by Virginia settlers, led by Nathaniel Bacon against the rule of Governor William Berkeley. The concrete reason to start Rebellion was Governor's refusal to answer on a series of Native Americans attacks on the frontier settlements. Also, many colonists had an ambition to attack the western frontiers and take away the land from Indians, but they were stopped by Berkeley. Some historians also say that the cause of Rebellion was Bacon's power play against Berkeley and his favoritism towards certain members of court.
