King Ragnald of the Isle of Man, referred to in some texts as Reginald, was the younger brother of the rightful successor to the throne and illegitimately rose to power, usurping his brother's right.
In the year 1219, he resigned his rulership to the Holy See, imitating King John of England, though he remained as king of the island.
In the year 1226 he was killed by his brother Olaf, the rightful heir to the throne.
His brother succeeded him as King Olaf II of the Isle of Man.
