The Central Lowland is a flat-lying regionlocated between the Appalachian Mountains to the east and the GreatPlains to the west (Figure 4.5). It extends from the Canadian Shield in the north to the Atlantic Coastal Plain in the south and is part of the North American craton (the older, stable part of the continent).
In 1763, at ethe end of the French and Indian War, the British issued a proclamation,mainly intended to conciliate the Indians by checking the encroachment of settlers on their lands. In the centuries since the proclamation, it has become one of the cornerstones of Native American law in the United States and Canada.
