I am guessing that you mean the war debt from the French andIndian War (Seven Years War) which ended in 1763. This debt was thereason the British tried to impose taxes on their American coloniesin ways they never had before, beginning the train of events thatled to the Revolution.The fact was that most of the troops fighting for the Britishcause in America during the French and Indian War were colonists,raised and equipped at the expense of the colonies. The coloniststhus thought they had ALREADY been taxed to pay the costs of thewar, and that the war in North America would not have been wonwithout their participation as soldiers. The result of the war wasthe complete expulsion of the French from North America and vastnew territories for Great Britain, including the entire massiveprovince of Quebec. To now present the colonies with a bill foradditional costs of the war seemed greedy and ungrateful.
