Answer:
French and Indian War (1754-1763), also known as the Seven Years' War.
Explanation:
(I tried to explain it)
The event that made British people upset both in the American colonies and back in England was called the French and Indian War. This war was fought between the British and French, along with their Native American allies, over control of land in North America.
After the war, the British government needed money to pay for the costs of fighting. To raise this money, they imposed new taxes and rules on the American colonies. This made the American colonists angry because they felt they were being treated unfairly and taxed without having a say in the British government.
In England, the war also caused a lot of financial problems. The government had to borrow a lot of money to pay for it, which led to higher taxes and debt for the British people.
Because of these troubles, the British government started thinking differently about how to manage their colonies and fight wars in the future. They wanted to have more control over the colonies to avoid similar conflicts and to protect their interests against other countries like France and Spain.
So, the French and Indian War changed how Britain treated its colonies and how it fought wars afterward
