Proclamation of 1763. In the aftermath of the French and Indian War, the British crown issued this proclamation, which severely limited colonists' access to land west of an imaginary line running down the crest of the Appalachain Mountains. With this attempt to reorganize British control in North America and maintain orderly relations with Native peoples, George III further alienated colonists who saw western expansion as an inevitable process. Many provisions in the Proclamation remained intact until 1776, although incursions by colonists into land west of the Proclamation Line were common.
