Final answer:
The French and Indian War was caused by competition for control over the Ohio River Valley between the French and British. Its effects included a shift in power in North America, increased tensions between Britain and its American colonies, and strained relations between Native American tribes and European powers.
Step-by-step explanation:
The French and Indian War, also known as the Seven Years' War, was a conflict between the French and British in North America from 1754 to 1763. The main cause of the war was the competition between the two European powers for control over the Ohio River Valley. The French wanted to maintain their influence over the region, while the British sought to expand their territory and influence.
The war had several effects. Firstly, it led to a significant shift in the balance of power in North America, with the British emerging as the dominant colonial power. As a result, France lost most of its colonies in North America. Secondly, the war left Britain heavily in debt, which ultimately led to increased tensions and taxes on the American colonists, contributing to the eventual outbreak of the American Revolution. Lastly, the war also strained relationships between Native American tribes and European powers, as many Native American groups had allied with the French and suffered consequences after their defeat.
