as well as the ruler of Dublin. Sigurd was to marry Muirchertach's daughter Bjaðmunjo, a young Irish princess and for a short period, queen. The marriage might not even have been consummated. When King Magnus was ambushed and killed in Ulaid by an Irish army in 1103, the 14-year-old Sigurd returned to Norway along with the rest of the Norwegian army, leaving his child-bride behind. Upon arriving in Norway, he and his two brothers, Øystein and Olav, were proclaimed kings of Norway and jointly ruled the kingdom together for some time. The expeditions conducted by Magnus were somewhat profitable to the Kingdom of Norway, as the many islands under Norwegian control generated wealth and manpower. However the Hebrides and Man quickly re-asserted their independence after Magnus' death. Norwegian Crusade In 1107, Sigurd led the Norwegian Crusade to support the newly established Kingdom of Jerusalem which had been founded after the First Crusade. He was the first European king to personally lead a crusade, and his feats earned him the nickname Jorsalafari. Sigurd possessed a total force of about 5000 men in about 60 ships, as recorded by the sagas. The two kings, Øystein and Sigurd, initially disputed about who should lead the contingent and who should remain home to rule the kingdom. Sigurd was eventually chosen to lead the crusade, possibly because he was a more experienced traveler, having been on several expeditions with his father, Magnus III, to Ireland and islands in the seas around Scotland. Sigurd fought in Lisbon, various Mediterranean islands and Palestine. He would often fight the enemies himself, amongst his loyal soldiers and kinsmen; they were continually victorious and vastly successful, gaining considerable amounts of treasure and booty. However, the loot probably never reached Norway, as Sigurd left almost everything he had gained in Constantinople. On his way to Jerusalem (Jorsala) he visited the Norman King Roger II of Sicily in his castle at Palermo. Upon arriving in the Holy Land he was greeted by King Baldwin I of Jerusalem. He received a warm welcome, and spent much time with the king. The two kings rode to the Jordan River, where Sigurd might have been baptized. King Baldwin asked Sigurd to join him and Ordelafo Faliero, Doge of Venice in the capture of the coastal city of Sidon, which had been re-fortified by the Fatimids in 1098. The Siege of Sidon was a great success
