Why did Pontiac stage an uprising in 1763?

Pontiac's uprising in 1763 was driven by Native American dissatisfaction with British policies and encroachments following the French and Indian War. After the British gained control of former French territories, they imposed restrictions on trade and land use, which angered various tribes. Pontiac, a leader of the Ottawa tribe, sought to unite several tribes to resist British expansion and protect their lands and way of life. The uprising aimed to expel British settlers and restore Native autonomy in the Great Lakes region.
