It was a pivotal moment in British history. On 25 September 1237, Alexander II of Scotland and Henry III of England signed a formal agreement officially defining the border between their kingdoms - a boundary that largely endures to this day. This treaty, which aimed to resolve long-standing territorial disputes, also laid the foundation for more stable relations.
