Jeremiah Dixon and Charles Mason started to survey the Mason-Dixon Line in 1763. This line marked the border between Pennsylvania and Maryland. They finished their work on December 26, 1767. Originally their work was to settle a very contentious land dispute between the Penn family (Pennsylvania) and the Calvert family (Maryland). Later, as the Civil War approached, the line somewhat divided the country into the north and the south. Older children could read about the history of the Mason-Dixon Line at: Mason-Dixon Line.
