Question: King of Norway Magnus Barefoot launched aggressive military campaigns in this region that was at times independent of external control and was known to the Norse as what?

<P0-S0> 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. <P0-S1>  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. <P0-S2>  The historical record is incomplete, and the kingdom was not a continuous entity throughout the entire period. <P0-S3>  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. <P0-S4>  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. <P0-S5>  At times there also appear to have been competing claims for all or parts of the territory. <P0-S6>  The islands involved have a total land area of over 8300 km2 and extend for more than 500 km from north to south. <SEP> <P1-S0> Radama I "the Great" (1793–1828) was the first Malagasy sovereign to be recognized as King of Madagascar (1810-1828) by a European state. <P1-S1>  He came to power at the age of 18 following the death of his father, King Andrianampoinimerina. <P1-S2>  Under Radama's rule and at his invitation, the first Europeans entered his central highland Kingdom of Imerina and its capital at Antananarivo. <P1-S3>  Radama encouraged these London Missionary Society envoys to establish schools to teach tradecraft and literacy to nobles and potential military and civil service recruits; they also introduced Christianity and taught literacy using the translated Bible. <P1-S4>  A wide range of political and social reforms were enacted under his rule, including an end to the international slave trade, which had historically been a key source of wealth and armaments for the Merina monarchy. <P1-S5>  Through aggressive military campaigns he successfully united two-thirds of the island under his rule. <P1-S6>  Abuse of alcohol weakened his health and he died prematurely at age 35. <P1-S7>  He was succeeded by his highest-ranking wife, Ranavalona I. <SEP> <P2-S0> 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. <P2-S1>  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. <P2-S2>  The historical record is incomplete and the kingdom was probably not a continuous entity throughout the entire period. <P2-S3>  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. <P2-S4>  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. <P2-S5>  At times there also appear to have been competing claims for all or parts of the territory. <P2-S6>  The islands involved have a total land area of over 8300 km2 and extend for more than 500 km from north to south. <SEP> <P3-S0> Magnus Olafsson (Old Norse: "Magnús Óláfsson", Norwegian: "Magnus Olavsson"; 1073 – 24 August 1103), better known as Magnus Barefoot (Old Norse: "Magnús berfœttr", Norwegian: "Magnus Berrføtt"), was King of Norway (as Magnus III) from 1093 until his death in 1103. <P3-S1>  His reign was marked by aggressive military campaigns and conquest, particularly in the Norse-dominated parts of the British Isles and Ireland, where he extended his rule to the Kingdom of the Isles and Dublin.
