The Mason–Dixon Line was surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon in the resolution of a border dispute between British colonies in Colonial America.
One hundred years after Mason and Dixon began their effort to chart the boundary, soldiers from opposite sides of the line let their blood stain the fields of Gettysburg, Pennsylvania, in the Southern states’ final and fatal attempt to breach the Mason-Dixon line during the Civil War.
