context_page_description: Magnus Olafsson, better known as Magnus Barefoot, was King of Norway from 1093 until his death in 1103. His reign was marked by aggressive military campaigns and conquest, particularly in the Norse-dominated parts of the British Isles, where he extended his rule to the Kingdom of the Isles and Dublin.
  As the only son of King Olaf Kyrre, Magnus was proclaimed king in southeastern Norway shortly after his father's death in 1093. In the north his claim was contested by his cousin, Haakon Magnusson, and the two co-ruled uneasily until Haakon's death in 1095. Disgruntled members of the nobility refused to recognise Magnus after his cousin's death, but the insurrection was short-lived. After securing his position domestically, Magnus campaigned around the Irish Sea from 1098 to 1099. He raided through Orkney, the Hebrides and Mann, and ensured Norwegian control by a treaty with the Scottish king. Based on Mann during his time in the west, Magnus had a number of forts and houses built on the island and probably also obtained suzerainty of Galloway. He sailed to Wales later in his expedition, winning control of Anglesey after repelling the invading Norman forces from the island.
context_section_description: Magnus sought to re-establish Norwegian influence around the Irish Sea. He attempted to install vassal king Ingemund in the Southern Isles in 1097, but the latter was killed in a revolt. It is unclear what Magnus' ultimate ambitions were, and the significance of his campaign has been downplayed by modern English historians. English chronicler William of Malmesbury believed that Magnus sought to capture the throne from William II of England (in common with the ambitions of his grandfather, Harald Hardrada). Historians have speculated that he wanted to establish an empire which included Scotland and Ireland, although most modern Norwegian and Scottish historians believe his chief aim was simply to control the Norse communities around the Irish Sea. While he may have been influenced by Ingemund's murder, the Orkneyinga saga claims that Magnus was persuaded by a son of an Orkney earl, Haakon Paulsson, who wanted an earldom for himself. It is also possible that Magnus wished to provide a realm outside Norway for his eight-year-old son Sigurd, who accompanied him. Magnus sailed into the Western Sea in 1098, arriving in Orkney with a large fleet. The Chronicles of the Kings of Mann and the Isles claim that he had 160 ships, but English chronicler Orderic Vitalis states that his fleet consisted of 60 ships. Based on this, P. A. Munch suggests an initial fleet of 160 ships, of which 100 were from the leidang (public levy) and returned shortly after arrival; the fleet accompanying Magnus southward in the campaigns consisted of 60 royal and baronial ships. According to Førsund, the low estimate of 120 men per ship means 8,000 men in the royal and baronial ships and 12,000 from the leidang ships. However, many historians believe that ship numbers in old naval campaign accounts are exaggerated.
  After his arrival, Magnus began negotiations with Scottish and Irish kings about the hird and control of land in Scotland, Ireland and the surrounding islands. Upon arriving in Orkney, he sent the earls Paul and Erlend Thorfinnsson away to Norway as prisoners on a leidang ship, took their sons Haakon Paulsson, Magnus Erlendsson and Erling Erlendsson as hostages and installed his own son Sigurd as earl. Magnus then raided Scotland, the Southern Isles and Lewis. Meeting no significant opposition, he continued pillaging the Hebridean islands of Uist, Skye, Tiree, Mull and Islay, and the peninsula of Kintyre; Iona was visited, but not pillaged. Magnus is also recorded as warring in Sanday, although the exact location is unclear (there are three islands with that name in the region). On entering the Irish Sea, he lost three leidang ships and 120 men in Ulster. Magnus then continued to Mann, where the earl Óttar fell in a violent battle; he also chased (or captured) Lagman Godredsson, King of the Isles. Mann came under Norwegian control, and Magnus and his men stayed on the island for a time. During his time there, he organised Norwegian immigration to the island and had several forts and houses built (or rebuilt) using timber from Galloway on the Scottish mainland. This implied he had subdued part of that region too, reducing its chieftains to tributaries.
  Magnus may have intended to invade Ireland next, only to find he had overextended himself. He may have been approached by Gruffudd ap Cynan, King of Gwynedd, who had been driven to Ireland by the Norman earls Hugh of Montgomery and Hugh d'Avranches. With six ships (according to Orderic Vitalis), Magnus steered towards Anglesey in Gwynedd, Wales. Appearing off the coast at Puffin Island, he interrupted a Norman victory celebration after their defeat of the Gwynedd king—for the Welsh, "so opportunely it was ascribed to divine providence" according to historian Rosemary Power (although Magnus had not necessarily intended to side with them). In the ensuing battle (known as the Battle of Anglesey Sound, according to Power "the most widely reported event in the history of Magnus"), Magnus shot Hugh of Montgomery dead with an arrow through his eye and defeated the Norman forces.
