The Act Summarized
The Royal Proclamation of 1763 was issued October 7, 1763, by King George III after Great Britain's procurement of French region in North America after the end of the French and Indian War/Seven Years' War, in which it restricted all pioneers from settling past a line drawn along the Appalachian Mountains.
How The Colonies Reacted
The colonists were mad about the Proclamation because it gave the crown a monopoly on land west of the Appalachian mountains. So instead of obeying the Proclamation they decided to ignore it.
