Answer: Taxation without the representation
Explanation: After the French and Indian War, in which Britain won along with still its American colonies, it turned out that this victory would represent the beginning of the struggle of the colonists for independence and the American Revolution. Namely after the war, it was shown that the costs were very large for the British monarchy and one of the ways to recover was to introduce unreasonable fees for colonists. On the other hand, colonists who were outraged also by the other actions of Britain, reasoned that if they already paid high taxes, they should have their representatives in the British Parliament. Thus, the expression "taxation without representation" arose, which further angered the colonists, in addition to the already established humiliating attitude of Britain towards them.
