The Treaty of Newcastle was a treaty signed between King Henry III of England and King Alexander II of Scotland on 14 August 1244.
[1] The treaty was signed in the Northumberland village of Ponteland, eight miles northwest of Newcastle upon Tyne.
[2] The armies of England and Scotland were en route to engage in combat after disputes concerning the exact position of the nearby Scottish-English border, dating to the Battle of Alnwick in 1174, could not be resolved.
After the two opposing armies met near Newcastle Upon Tyne hostilities were set aside and a treaty signed.
[1] The treaty was sealed by the arrangement of the future marriage of Henry III's daughter, Margaret to Alexander II's son, Alexander III of Scotland.
