How were the borders of Maryland determined?

Answer 1

The borders of Maryland were established through a series of colonial charters and negotiations in the 17th century. The original charter granted to Lord Baltimore in 1632 defined the colony's boundaries, which included a portion of land between the Potomac River and the Chesapeake Bay. The borders were further refined through agreements with neighboring colonies, particularly Virginia and Pennsylvania. The Mason-Dixon Line, established in the 1760s, ultimately defined the northern boundary with Pennsylvania and has historical significance in the context of slavery and sectionalism in the United States.
