Mason–Dixon Line, Border line in the United States
The Mason-Dixon line is a demarcation line separating four U.S. states.
It was surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon to resolve a border dispute involving Maryland, Pennsylvania, and Delaware.
In popular culture, it is often seen as the cultural boundary between the Northern and Southern United States.
Nowadays, it is considered part of the informal boundary between the Southern and Northern United States.
The line is named after two Englishmen, Charles Mason and Jeremiah Dixon, who were hired to solve a violent border dispute.
