The causes of the rivalry between France and Britain were the disputes that developed over land in the colonies, control of the fur trade in the colonies, and the balance of power in Europe. These causes led to war. In the end, England became the most powerful nation in the world, and the mercantile system was revamped.
I will write about the wars King William's War, Queen Anne's War, King George's War, and the French and Indian War. Because of these wars, England became the most powerful nation in the world. Two wars were over who would succeed the thrones in Europe that became vacant with the deaths of the reigning monarchs.
King William's War was fought in the New World areas of the Great Lakes, Northern New England, Upper New York, the Ohio Valley, and the Southern frontier. In this war, the colonists bore the brunt of the fighting. The main result of this war was that the French had moved down the Mississippi to New Orleans and built forts along the way. This effectively kept the English colonists on the coast, east of the Appalachian Mountains.
Queen Anne's and King George's War dealt with the Spanish and Austrian Successions to the thrones respectively. The areas of fighting were the southern frontier, Quebec, the Saint Lawrence River, and Lake Champlain in Queen Anne's War; and in King George's War, the area of fighting was the Ohio Valley, the Great Lakes, and Nova Scotia. The results of these wars were that Britain gained possessions from France in the New World and Spain's possession of Gibraltar.
The final war, the French and Indian War, was the war in which England finally got rid of the French totally in Canada and the Mississippi, and Great Lakes line. The English to their detriment took Canada. The reason, the colonies now no longer dependent upon British protection and they could expand into the continent and take over the fur trade. American expansion and independence ruined the mercantile system.
Britain became a world power and no longer could practice the policy of keeping the balance of power on the European continent. The British in an attempt to slow the colonial expansion and calm the Indians down, enacted the Proclamation of 1763, which barred, temporarily, the expansion of the Colonies into the wilderness. This was also a temporary money-saving policy.
The British at first only wanted to have limited objective wars with France but because of the Americans, constant bickering with France and her Indian allies forced Britain to finally, and unequivocally destroy the French presence in North America. However, not all of the colonies wanted the wars because these wars hampered or destroyed their lucrative trade with the Indians. New York is an example. In New England, the war was a cause. The Americans wanted Canada to get rid of the French, not England.
