About the Mason Dixon Line
The Mason Dixon line is a property line that was surveyed and was decided in the 1770’s by James Mason and Jeremiah Dixon. In the years that lead up to the The United States Civil War, the majority of states north of the Mason Dixon line had by states votes declared slavery was illegal. In direct opposition, the majority of states south of the Mason Dixon line had voted on slavery and decided it was legal. The majority of these southern states declared they were no longer members of the union that was the United States of America. This declaration began the United States Civil War.
