Quick Summary

The Treaty of Shrewsbury, signed in 1267, was an agreement between Llywelyn ap Gruffudd, the prince of Gwynedd, and King Henry III of England. This treaty recognized Llywelyn as the prince of Wales, with the authority to receive homage from other Welsh princes.1

Shrewsbury, a town strategically located near the England-Wales border, has a long history of involvement in conflicts between the two regions. The town was a seat for Welsh princes before being incorporated into the Anglo-Saxon kingdom of Mercia. Throughout the subsequent centuries, Shrewsbury frequently experienced wars with the Welsh, and the castle was rebuilt by Edward I. The establishment of law and order in the Marches, the border region, along with trade in Welsh wool, brought prosperity to Shrewsbury in the late Middle Ages.2
