Final answer:
The French provided Native American tribes with European weapons, altering the balance of power during conflicts. They allied with the Mughal Empire in India against the British during the French and Indian War. The post-war treaty reduced French influence and support for Native American tribes.
Step-by-step explanation:
The French introduced several key military resources and strategies into Indian warfare, significantly altering the dynamics of Native American conflicts and European colonial interests in North America. Notably, they provided muskets and other European metal weapons to certain tribes, such as the Algonquian, which led to shifts in power as these tribes gained advantages over rivals like the Iroquois. During the French and Indian War, which is the American name for the broader Seven Years' War, the French supported the Mughal Empire against British expansion in India. The French engaged in military actions such as pressuring the ruler of Bengal to attack British Fort William near Calcutta in 1756. Post-war, the treaty ending the conflict diminished the French presence and influence in North America, which meant a loss of a valuable trade partner and military aid for many Native American tribes who had allied with them.
