Final answer:
Britain faced a significant problem in the form of accumulated war debt at the end of the French and Indian War, leading to tax measures that strained relations with American colonies.
Step-by-step explanation:
At the end of the French and Indian War, Britain faced accumulated war debt as a major problem. The war nearly doubled the British national debt, with the amount rising from £75 million in 1756 to £133 million by 1763, and interest payments consuming over half the national budget. Alongside managing the enlarged empire, Britain needed to find ways to increase revenue to replenish the treasury, which involved imposing new taxes and regulations on its American colonies. This economic pressure subsequently led to tensions that contributed to the American Revolution.
