The treaty that ended hostilities between England and France in 1763 was the **Treaty of Paris**. This agreement significantly reshaped North American territorial claims by granting Britain control over Canada and vast territories east of the Mississippi River. As a result, France ceded its North American holdings, which diminished its influence in the region. The treaty also planted the seeds of colonial discontent, as Britain's war debts led to increased taxation on American colonies. This ultimately contributed to the revolution’s causes and reshaped the geopolitical landscape of North America, establishing British dominance.
