Treaty of Montgomery
The Treaty of Montgomery was agreed on 29 September 1267 between Henry III of England and Llywelyn ap Gruffudd, brokered by the papal legate Ottobuono. Henry recognised Llywelyn as Prince of Wales, with overlordship over the other Welsh lords, in return for homage and a large payment. It marked the height of the native Welsh principality, but disputes over the payments and homage led to Edward I's invasion of 1277.
