Answer:
Taxing without representation
Step-by-step explanation:
Taxing without representation without representation is one of the biggest reasons leading up to the American revolution.
At that time , the British government imposed a really high tax rate for American colonies in order to pay for it war debt. But, they did not give the colonies with any seats within the government. This made the American colonies have no legal measures that they can pursue to negotiate for their behalf within the government.
Thomas Jefferson was one of the figure that popularized this British Government's flaw. He stated in his writings that the only way for the colonists to erase this unfair taxation is through military's revolution.
