Final answer:
The French and Indian War changed society and politics in North America, particularly for Native Americans, by weakening their position in trade and land negotiations with the British and causing increased tensions with the settlers.
Step-by-step explanation:
The French and Indian War, also known as the Seven Years' War, had a significant impact on society and politics in North America, especially for Native Americans. With the French defeat, many Native Americans who had sided with France lost a valued trading partner and bargaining power over the British. Additionally, the British military presence and settlers' encroachment on Native American land worsened relationships. The British reduced the amount of gunpowder and ammunition they sold to Native Americans, leading to further tensions.
