With American Indians randomly attacking the colonies, grave economic problems, corruption in the government, a desire for a representative government, and no help from Great Britain, the American colonies were on the brink of rebellion. All that was left to ignite the rebellion was a leader and a spark. Both of these came in the years to follow 1675. There were great economic problems in the colonies at the time. For one thing, the prices of tobacco, the major economic base of the colonies, were falling fast. To add to the decrease in tobacco price, Great Britain was also increasing taxes on the Americans. This did not help the situation in the colonies.
