The Treaty of York was signed by Henry III of England and Alexander II of Scotland in 1237. The treaty set the border between England and Scotland.
The agreement specifically defined the boundary between the two kingdoms as running between the Solway Firth (in the west) and the mouth of the River Tweed (in the east). It remains the border to this day, with the exception of a small area around Berwick, which was taken by England in 1482.
With the Treaty of York, Alexander II abandoned traditional Scottish claims to the regions of Northumbria, south of the Tweed, and Cumbria. Northumbria had history, predating the competing claims of England and Scotland, as a kingdom strethching from the Humber to the Forth.
