Britain gained large amounts of territory from France primarily through military victories during the Seven Years' War, particularly in North America and India. The Treaty of Paris in 1763 formalized these gains by ceding Canada and various territories east of the Mississippi River to Britain. Additionally, Britain's naval superiority played a crucial role in disrupting French supply lines and colonial efforts. This expansion significantly increased British influence and territory globally.
