Final answer:
The French and Indian War led to Britain being deeply in debt due to the high costs of war efforts.
Step-by-step explanation:
One effect of the French and Indian War was that Britain was deeply in debt. The expenditures of the war nearly doubled Britain's national debt from £75 million in 1756 to £133 million in 1763.
This significant increase was due to Britain's efforts to gain supremacy in North America and the high costs associated with mobilizing troops and securing alliances.
In the aftermath of the war, Great Britain not only expanded its empire but also grappled with the financial ramifications, which later led to the imposition of taxes on the American colonies, contributing to the unrest that would eventually culminate in the American Revolutionary War.

The expenses of the war, including troop recruitment and payment, led to a financial burden on Great Britain, which needed more revenue to replenish its coffers. This debt was a major cause of concern for the British government.
