Above is a general map of the original 13 Colonies before 1763. Notice how boundary lines extended to the Mississippi.
There were some that didn’t. Those which had fixed western boundaries were Massachusetts, Rhode Island, Connecticut, New Jersey, and Delaware.
So what about all the others? Maine, New York, Pennsylvania, Maryland, Virginia, North Carolina, South Carolina, and Georgia.
In such instances geography didn’t seem to fully serve to determine the line.
Why didn’t the original colonists just stop at the Appalachian Divide.
At the conclusion of the British America fight against New France in what is called the French and Indian war, England seemingly came out on top.
Really? That war commenced in North America in 1754 and became a global conflict involving five continents in what has been named the Seven Year War which started in 1756.
Both, if they really were distinct ended at the same time.
On October 7, 1963, King George III issued “The Royal Proclamation of 1763.” In it the King of England DECIDED that England had title that which was east of the Appalachian Divide. All that which was west westward became the “Indian Reserve.”
A little problem though, many of the British colonists who had fought on the ground in the land had staked property to the west of that line. So, effectively not only did King George III DECIDE that he wouldn’t provide a shield of defense for them, they were “forbidden” from living their life at the very place where the had fought to preserve it. Not cool!
The Royal Proclamation of 1763 essentially serves as a settlement agreement it would seem.
But, this still doesn’t explain why the boundaries of the original colonies not constrained by the geography of other colonies had not simply originally kept to the peaks of Appalachia.
It seems that this question might be worthy of further investigation and revisit. Cheers!
