ON THIS DAY IN UNITED STATES HISTORY
May 25, 1738
A Treaty is Signed in London Ending
a War Between Pennsylvania and Maryland
On this day in 1738, the Cresa's War (also known as the Conojocular War) officially came to an end with the signing of a treaty arranged and encouraged by King George II. The conflict started in 1730 after a disupte over property rights and escalated in 1736 and 1737 when both sides involved their militias.
The fighting ended on May 25 with the signing of the treaty and both sides agreed to a temporary border and a swap of prisoners. The final border was not determined until 1767 when the Mason-Dixon line was recognized as the permanent border. The area of dispute is now known as York County, Pennsylvania.
