Rǫgnvaldr's papal submission may have also been linked to his feud with Óláfr. For example, in the last hours of his life, John appealed to Pope Innocent III to ensure the succession of his young son, Henry III. Although the chronology of dissension between Rǫgnvaldr and Óláfr is not entirely clear, the hostilities which entangled Rǫgnvaldr's son broke out in the 1220s. Rǫgnvaldr, therefore, may have intended to secure, not only his own kingship, but also the future succession of his son. In any case, it is unknown how well Rǫgnvaldr kept his obligations to the papacy. The limited surviving evidence of communications between Mann and Rome appear to show that his commitments were not taken up by his successors. Nevertheless, centuries after his death, Rǫgnvaldr's deal with the papacy was commemorated by a fresco in the Vatican Archives.
