Seven Years’ War (Plain-Language Summary)

 The Seven Years’ War (1756–63) was the first global war. In North America, Britain and France fought each other with the help of Indigenous allies. At the end of the war, France gave Canada (Quebec) and Ile Royale (Cape Breton) to Britain, among other territories. This is the reason that Canada has a British monarch but three founding peoples — French, British and Indigenous.

Seven Years' War, Map

The Seven Years’ War (1756–63) was the first global war. It was fought in Europe, India and North America. In Europe, Britain, Prussia, and Hanover fought against France, Austria, Sweden, Saxony, Russia, and Spain. In India and North America, Britain fought against France. One of the main causes of the war was the competition between France and Britain for colonies and trade.

In North America, both Britain and France had Indigenous allies. The French and their allies won some important victories early in the war. They won battles at Fort Oswego (located on Lake Ontario) and at Fort William Henry (located on Lake George). For awhile, France had complete control of the Great Lakes. In 1758, however, the British and their allies began to win the war.

That summer, the British captured Louisbourg (Cape Breton). This was a very important victory. The French fort at Louisbourg had prevented the British from entering the St. Lawrence River. Now, the British could sail down the St. Lawrence and attack Quebec. In August 1758, the British also destroyed Fort Frontenac (Kingston, Ontario).

In January 1759, the British navy captured the Island of Guadeloupe in the Caribbean. In July, they won a victory at Fort Niagara. They now controlled the entire Niagara region. Then, in September, the British and their Indigenous allies won a key victory on the Plains of Abraham (located in Quebec City). One year later, the British and their Indigenous allies won yet another important victory in Montreal. This victory effectively ended the war. France no longer wanted to continue fighting.

In 1763, France and Britain signed the Treaty of Paris to formally end the Seven Years’ War. France gave control of Ile Royale (Cape Breton), Canada (Quebec), the Great Lakes Basin and the east bank of the Mississippi to Britain. Britain gave Guadeloupe back to France and allowed France to keep the islands of Saint-Pierre and Miquelon (located on the St. Lawrence River). Thanks to the Treaty of Paris, Britain became the leading colonial power in North America.
