Answer:
King George made the Proclamation of 1963 in response to Pontiac's Rebellion. (Rebellion lead by Ottwa Chief)
Explanation:
Dissatisfied with British rule, a rebellion rose up from the Ottawa chief Pontiac. His warriors attacked about a dozen British forts, and raided many frontier settlements. Hundreds died in the skirmish. In response, the British handed out small-pox infected blankets to Pontiac's warriors. Recognizing that the lands to the west were too dangerous, King George made a proclamation, known as the Proclamation of 1763, that forbid any settlement of western land.
