The French had settled in the New World and wished to gain prominence in colonization. When the British approached their settlements and colonies, they became very defensive, believing that they would be forced into a fight and hoping to win. The Natives just wanted the colonists to leave them be and for them to get their land back.
Effects of the war
It's OUR land now, so move out.
Prominent figures in the war were important to the future of North America were on all three opposing sides, the British, the French, and the Natives. On the British side, William Pitt turned the war around for the British, and is partly responsible for their victory. British general later George Washington became the first President of the United States of America. De Montcalm commanded the French forces in North America during the war. Finally, Tanaghrisson was a very effective native leader and helped his people during the war.
The French and Indian War lasted for a long time, with many battles. The Battle of the Monongahela was an unexpected victory for a small French force against a stronger British group. The Battle of Minorca was the first naval battle of the war, also won by the French. But in time, the British won and forced the French out of North America, taking control of the lands and its resources.
With the French forced out and all of this new land in British control, they wanted to keep and drove the Native peoples away. They took their land, many times by force, and moved in once they were gone. The British victory was very bad news for the Natives, whom would be treated unfairly for many years after.
