A bilingual (Latin/English) royal letter granting safe conduct to Reginald, King of the Isles, when visiting the English King to do homage and address grievances caused by his subjects in England and Ireland. The document establishes a 15-day protection period after Easter in the second year of Henry III's reign (1218) and instructs the Justice of Ireland not to harm the Isles' king or his people. This is an early medieval example of Man's relationship with the English Crown.
