The 1763 Proclamation flag was first hoisted along the original line as defined by King George III. This Royal Proclamation was issued on October 7, 1763 during the George Greenville administration of Original Congress (Parliament). Among several things, it became the border for several English Colonies from West Florida to Quebec. During this time Canada, Quebec, and the 13+ North American Colonies were united under one government.
The 1763 Proclamation used water sheds to set the western border of the several colonies, as well as the northern borders for the lost colonies of East and West Florida and southern borders of Quebec. Basically the Eastern Mississippi Valley and Great Lakes were supposed to become an Indian Reserve/Reservation. Before the American Revolution these borders would move, but as a heritage trail, the original 1763 borders is demarcated and honored with this flag.
The 1763 Proclamation Flag uses the old UK flag pattern of Scotland and England, without St. Patrick's Cross since it was not included until 1801, after 'Ireland' became a part of the UK. Likewise there is a red border with white broken edges to represent a fence.
This is a cultural heritage flag, that does not have any irredential connotation. It can be used to underscore this moment in history to educate Americans, Canadians, and the British about their common heritage. It is an educational-geographic flag that can be flown anywhere in Canada and the United States that made up this border in 1763.
