Maryland's charter, granted in 1632, included old Philadelphia since it made the 40th parallel, which crosses the river near this point, her northern boundary. This charter conflicted with the charter given William Penn in 1681. After more than eighty years of legal disputes, a survey in 1763-67 fixed the boundary at the 39-43' parallel. This boundary acquired national fame as the Mason and Dixon line.
