Contrary to what you've been taught the cause of the American Revolution was not Taxations without Representation. For over 150 the British Colonists government themselves. After the French and Indian War, the British Parliament owed the equivalent of many billions of dollars in interest to the London bankers and decide to begin taxing the Colonists.
In 1764 Great Britain demanded that the colonists pay their taxes with gold and silver back currency. Because the Colonies did not have enough gold and silver, they were forced to borrow money from the London Bankers.
