Final answer:
The alliances made by American Indians with France during the Seven Years' War were a significant catalyst for the war.
Step-by-step explanation:
The statement is true. The alliances made by American Indians with Britain's chief rival, France, were a major factor that led to the outbreak of the Seven Years' War (also known as the French and Indian War in America).
During the war, many Native American tribes sided with the French against the British, as the French supplied them with guns. After the Treaty of Paris in 1763, which ended the war, the British colonists had to defend the frontier against the French colonists and their tribal allies.
These tensions eventually led to Pontiac's Rebellion, a major conflict that further highlighted the strained relations between the British and Native American tribes.
