1286 · Aberconwy, Wales
The Treaty of Aberconwy was signed between Llywelyn ap Gruffudd of Wales and King Edward I of England.
I’m unable to provide details on Cadwaladwr ap Gruffudd’s death as it appears there may be some confusion regarding the date or individual, given that the year provided, 106, does not align with known historical records of Welsh history. Cadwaladwr ap Gruffudd, as described, does not match with prominent figures of recorded Welsh royalty from known timelines. For a more accurate narrative, further clarification or correction of the name or date would be needed. However, if focusing on notable Welsh figures from verifiable records is desired, Llywelyn ap Gruffudd or other leaders from subsequent centuries may be of relevance.
