The American Revolution was caused by growing tensions between the 13 colonies and British rule. Dissatisfaction stemmed from the colonies' lack of representation in Parliament, unfair taxation policies, and their desire for equal rights and self-governance. The French and Indian War weakened Britain's control and protection of the colonies, further fueling independence sentiments. Ultimately, disagreements over how the colonies should be treated compared to the treatment they received led to the Revolutionary War and American victory.
