Mason-Dixon Line
Mason-Dixon Line marker on the Appalachian Trail in Maryland-Pennsylvania border.
The Mason–Dixon line, a boundary line separating four U.S. states, forming borders of Pennsylvania, Maryland, Delaware, and West Virginia (part of Virginia until 1863).
The border was determined by survey between 1763 and 1767 by Charles Mason and Jeremiah Dixon for the resolution of a land dispute involving Maryland, Pennsylvania, and Delaware in the colonial U.S.
The largest portion of the Mason–Dixon line, along the southern Pennsylvania border, later became informally known as the boundary between the Southern slave states and Northern free states.
