The British government also came to the conclusion that colonists and Native Americans must be kept apart. On October 7, 1763, the Crown issued the Royal Proclamation of 1763, an effort to reorganize British North America after the Treaty of Paris. The Proclamation had already been worked on when Pontiac's War erupted. It was hurriedly issued after news of the uprising reached London. Officials drew a boundary line between the British colonies along the seaboard, and Native American lands west of the Allegheny Ridge (i.e., the Eastern Divide). This created a vast 'Indian Reserve' that stretched from the Alleghenies to the Mississippi River and from Florida to Quebec. It also confirmed the demarcation line that had been set before the war by the Treaty of Easton in 1758. By forbidding colonists from trespassing on Native lands, the British government hoped to avoid more conflicts like Pontiac's Rebellion. "The Royal Proclamation," writes historian Colin Calloway, "reflected the notion that segregation not interaction should characterize Indian-white relations."
