The Treaty of Paris ended the French and Indian War that took place between Great Britain and France. It also culminated in Great Britain gaining control over the colonies in North America.
The Treaty of Paris ceded all of the French North American colonies to Great Britain, putting an end to any further threat from France on the continent. Spain, France's ally, gave Florida to Great Britain in exchange for Cuba. Spain kept the Port of New Orleans and took over France's territories to the west of the Mississippi River. All of the other colonies in North America became British. The French kept three Caribbean islands: Martinique, St. Lucia and Guadeloupe.
The party that lost the most with the treaty was neither the British, French or Spanish; it was the Native Americans. During the war, the Native Americans played both sides in an attempt to preserve their own lands and people. After the treaty was signed, they no longer had that option.
The Treaty of Paris resulted ultimately in the independence of the American colonies. With France no longer a threat to Great Britain in North America and Spain far away, Great Britain removed many of its soldiers from the continent. In addition, the colonists no longer had to depend on the British for protection from the French.
