Join Cliveden on #GivingTuesday as we kick-off 12 Ways at Cliveden! Beginning December 1st, we will highlight all that we were able to accomplish this year. 2020 certainly brought challenges, but there were surprising rewards as well. Be sure to follow us on social media and on our website: there will be videos detailing Cliveden’s year, the various ways your support made it all possible, and how you can help us continue sharing Cliveden’s diverse history in 2021. Feel free to share with your family and friends.
We hope you’ll participate with us for the international day of giving on December 1st. Thank you and we wish you a safe and healthy holiday season.
November 1865: Benjamin Chew IV (1830-1885), the great-grandson of Benjamin Chew, Sr. (1722-1810), presented the original survey map of the Mason-Dixon line to the Historical Society of Pennsylvania. The Mason-Dixon line established the border between Pennsylvania and Maryland and was named after British surveyors Charles Mason (1728-1786) and Jeremiah Dixon (1733-1779).
The Mason-Dixon line ended the conflict between the Penn and Calvert families: both were granted land in ...the colonies by the British King, but the land grants overlapped, which made collecting taxes complicated. Mason and Dixon were hired to survey the boundaries between the two colonies, which they completed in 1767. Their work changed the geography of both PA and MD, making the Mason-Dixon line the first artificial boundary not marked by natural features such as a mountain or body of water. The Mason-Dixon line was later used as the border separating the North and the South prior to the Civil War and into the 20th century.
