This excerpt is from the Proclamation of 1763: "And We do further declare it to be Our Royal Will and Pleasure, for the present as aforesaid, to reserve under our Sovereignty, Protection, and Dominion, for the use of the said Indians, all the Lands and Territories not included within the Limits of Our said Three new Governments, or within
the Limits of the Territory granted to the Hudson’s Bay Company, as also
all the Lands and Territories lying to the Westward of the Sources of the
Rivers which fall into the Sea from the West and North West as aforesaid.
And We do hereby strictly forbid, on Pain of our Displeasure, all our loving
Subjects from making any Purchases or Settlements whatever, or taking
Possession of any of the Lands above reserved.” What effect did this provision of the proclamation have in the colonies?
