The Mason-Dixon line.
No, it happened to follow the border of Maryland and Pennsylvania, and divided slave country from free soil.And it wasn't the origin of 'Dixie', which was named after the widely-distributed ten-franc coin ('DIX') from when Louisiana was French.NEW ANSWER:The Mason and Dixon Line is usually thought of as the line that divides the North and South. Actually it is the east-west boundary line that separates Pennsylvania from Maryland and part of West Virginia, and the north-south boundary between Maryland and Delaware. Before the Civil War, the southern boundary of Pennsylvania was considered the dividing line between the slave and non-slave states.In the 1700's a boundary quarrel arose between Pennsylvania and Maryland. The two agreed to settle the dispute by having the land surveyed. In 1763, they called in two English astronomers, Charles Mason and Jeremiah Dixon. They completed the survey in 1767. The line was named after them.The surveyors set up milestones to mark the boundary. Through the years souvenir hunters removed many of the stones and used them as doorsteps and curbstones. Authorities finally recovered many of them, however, and nearly replaced all of the stolen markers.

"The Arc" that forms most of Delaware's northern boundary with Pennsylvania was defined as an arc 12 miles in radius from the then-New Castle County courthouse in the town of New Castle. Delaware's southern border was set by agreement between the Penn and Calvert families of Pennsylvania and Maryland respectively as a line (the Transpeninsular Line) which basically ran 35 miles west from Fenwick Island to the mid-point of the DelMarVa peninsula. Delaware's western boundary, which makes up the first 86 miles of the Mason-Dixon Line, runs generally northward to a tangent point on the 12-mile arc and then continues north to Pennsylvania's southern border. This actually left a small "wedge" between the arc and Pennsylvania's southern boundary; it was claimed by both Delaware and Pennsylvania until agreement was reached in 1893 and it became part of Delaware.
