Step-by-step explanation:
The French and Indian War lasted from 1754 to 1763. It was known as the Seven Years' War in Europe. The war began in the colonies and eventually spread to Europe and other parts of the world.
The war lasted that long due to various factors. One of the main reasons was the strategic importance of North America for both France and Britain. They were competing for control of valuable fur trade, land, and resources in the region. The war also involved various Native American tribes, who aligned themselves with either the French or the British.
Additionally, the war was characterized by a series of shifting alliances and military campaigns, which prolonged the conflict. The British initially faced challenges and defeats, but with increased reinforcements and native allies, they eventually gained the upper hand. The war came to an end with the signing of the Treaty of Paris in 1763, which resulted in significant territorial changes and solidified British control over North America.
