Final answer:
The French and Indian War's two main consequences include Great Britain's ascension as the preeminent power in eastern North America and the resulting strife with Native American tribes due to the Treaty of Paris 1763.
Step-by-step explanation:
The two consequences of the French and Indian War were that Great Britain became the dominant European power in eastern North America, and it created significant tension and eventual conflict with the Native American tribes. After the war, as a result of the Treaty of Paris 1763, Britain received all French territories east of the Mississippi River, with some exceptions, such as New Orleans and Louisiana.
However, France's native allies who had supported them during the conflict faced a loss of a trading partner and experienced reduced influence and autonomy under British rule, leading to simmering hostility and violence. This unrest later developed into Pontiac's Rebellion, exposing the racial and territorial tensions on the frontier.
