Main Street, near here, crosses a barely perceptible ridge line. This line divides water ﬂowing east to the Atlantic Ocean, via the Roanoke River basin, from water ﬂowing west to the Gulf of Mexico, via the New, Ohio, and Mississippi Rivers. In October 1763, by Royal Proclamation, King George III forbade Virginians to settle west of this line. Virginians considered the taking up of western land as their natural right. Shutting off access to this land was a provocation that accelerated the building momentum in Virginia for the coming American Revolution.
