The treaty that ended the Seven Years' War was the Treaty of Paris in 1763. This agreement significantly altered territorial claims in North America, asserting British dominance over Canada and vast territories east of the Mississippi River. France ceded most of its North American possessions, greatly affecting the geopolitical landscape. The consequences of the treaty laid the groundwork for future colonial tensions, as the British government sought to recoup war expenses through new taxes on colonies. Thus, this treaty had lasting impacts on the relationship between the colonies and the British crown.
