Question: The King of Mann's father was known as the King of what?
Context: Rǫgnvaldr Óláfsson (died 30 May 1249) was a mid-thirteenth-century King of Mann and the Isles who was assassinated after a reign of less than a month.  As a son of Óláfr Guðrøðarson, King of Mann and the Isles, Rǫgnvaldr Óláfsson was a member of the Crovan dynasty.  When his father died in 1237, the kingship was assumed by Haraldr Óláfsson.  The latter was lost at sea late in 1248, and the following year Rǫgnvaldr Óláfsson succeeded him as king. Mentuhotep was the non-royal father of the Ancient Egyptian king Sobekhotep III who ruled for about three years in the Thirteenth Dynasty, around 1750 BC.  Mentuhotep is mainly known from monuments of his son while he was king.  On these monuments appears also his wife Iuhetibu, who was called "king's mother".  On the monuments relating to Sobekhotep III, Mentuhotep bears the title "god's father".  The latter title is often given to non-royal fathers of kings.  Furthermore, from a high number of scarab seals there is known a military official with the title "commander of the ruler's crew".  This official had a son with the same title named Sobekhotep.  It seems possible that these scarabs belong to the "god's father" Mentuhotep before his son became king.  It is not known under which circumstances Sobekhotep III became king.  However, his father Mentuhotep had no known royal connections.  Two further sons are known, Seneb and Khakau.  They were bearing the title "king's son", albeit being evidently not the son of a king, but brothers of one. Haraldr Guðrøðarson was a mid thirteenth-century King of the Isles.  He was the son of Guðrøðr Rǫgnvaldsson, King of the Isles, son of Rǫgnvaldr Guðrøðarson, King of the Isles.  Haraldr Guðrøðarson and his predecessors were members of the Crovan dynasty, and ruled an island-kingdom that encompassed the Mann and portions of the Hebrides, variously known as the Kingdom of the Isles or the Kingdom of Mann and the Isles. Haraldr Óláfsson (died 1248) was a thirteenth-century King of Mann and the Isles, and a member of the Crovan dynasty.  He was one of several sons of Óláfr Guðrøðarson, King of the Isles, although the identity of his mother is uncertain.  When his father died in 1237, Haraldr succeeded to the kingship as a fourteen-year-old, and held the kingship for about a decade afterwards. Lǫgmaðr Guðrøðarson (] ) was a late eleventh-century King of the Isles, whose rise, reign, and fall from power are obscure.  He was the eldest son of Guðrøðr Crovan, King of Dublin and the Isles, a Norse-Gaelic dynast who conquered and ruled the kingdoms of the Isles and Dublin, before dying in 1095.  Three years after the latter's death, the Isles was conquered by Magnús Óláfsson, King of Norway, whose regime in the region lasted until his death in 1103.  The chronology of Lǫgmaðr's reign is uncertain: he may have begun his reign either before Magnús' conquest, during his regime, or after his demise. Bernice Albertine King (born March 28, 1963) is an American minister best known as the youngest child of civil rights leaders Martin Luther King Jr. and Coretta Scott King.  She was five years old when her father was assassinated.  In her adolescence, King chose to work towards becoming a minister after having a breakdown from watching a documentary about her father.  King was 17 when she was invited to speak at the United Nations.  Twenty years after her father was assassinated, she preached her trial sermon.  Inspired by her parents' activism, she was arrested multiple times during her early adulthood. Magnús Óláfsson (died 1265) was a King of Mann and the Isles.  He was a son of Óláfr Guðrøðarson, King of the Isles, and a member of the Crovan dynasty.  Magnús' realm encompassed Mann the parts of the Hebrides.  Some leading members of Magnús' family—such as his father—styled themselves "King of the Isles"; other members—such as Magnús and his brothers—styled themselves "King of Mann and the Isles".  Although kings in their own right, leading members of the Crovan dynasty paid tribute to the Kings of Norway and generally recognised a nominal Norwegian overlordship of Mann and the Hebrides. Aung Thet Mann (Burmese: အောင်သက်မန်း , ] ; born 19 June 1977), also known as Shwe Mann Ko Ko (ရွှေမန်းကိုကို ), is a Burmese businessman and currently CEO of Ayer Shwe Wah, a major Burmese company.  Aung Thet Mann's father is Shwe Mann, a former military general and currently Speaker of the Pyithu Hluttaw.  He graduated from the Yangon Institute of Economics.  Aung Thet Mann is married to Khin Hnin Thandar. The Kingdom of the Isles comprised the Hebrides, the islands of the Firth of Clyde and the Isle of Man from the 9th to the 13th centuries AD.  The islands were known to the Norse as the "Suðreyjar", or "Southern Isles" as distinct from the "Norðreyjar" or Northern Isles of Orkney and Shetland.  The historical record is incomplete, and the kingdom was not a continuous entity throughout the entire period.  The islands concerned are sometimes referred to as the Kingdom of Mann and the Isles, although only some of the later rulers claimed that title.  At times the rulers were independent of external control, although for much of the period they had overlords in Norway, Ireland, England, Scotland or Orkney.  At times there also appear to have been competing claims for all or parts of the territory.  The islands involved have a total land area of over 8300 km2 and extend for more than 500 km from north to south. Óláfr Guðrøðarson (] ), commonly known in English as Olaf the Black, was a mid 13th century sea-king who ruled the Isle of Man (Mann) and parts of the Hebrides.  Óláfr was the son of Guðrøðr Óláfsson, King of the Isles, King of Dublin, and his wife Finnguala, granddaughter of Muirchertach Mac Lochlainn, High King of Ireland, King of Cenél nEógain.  Óláfr was a younger son of his father; his elder brother Rögnvaldr more than likely had a different mother.  According to the "Chronicle of Mann", Guðrøðr appointed Óláfr as heir since he had been born "in lawful wedlock".  Whether or not this is the case, on Guðrøðr's death in 1187 the Manxmen instead appointed Rögnvaldr as king, as he was a capable adult and Óláfr was a mere child.  Rögnvaldr ruled the Crovan dynasty's island-kingdom for almost 40 years, during which time the half-brothers vied for the kingship.
