After the conquest of Jerusalem in 1099, one might have expected a visit from a monarch of European Christendom. However, the first king to journey to the Holy Land came from a distant realm not typically associated with deep Christian devotion: Norway. Sigurd I Magnusson (1090–1130), who became king in 1103, embarked on a voyage to the Mediterranean, seeking fame (frægð in Old Norse) and wealth, in line with Viking traditions. Leaving his kingdom in the hands of his two brothers, Sigurd departed in 1107 with 5,000 men, inspired by the news of Jerusalem’s conquest, thus initiating what became known as the Norwegian Crusade.  

This expedition was not solely spiritual but also economic and military, making it unique by blending Viking raiding traditions with Christian faith. Along their journey, Sigurd and his men traveled along the coasts of England, France, Spain, Sardinia, Sicily, and Greece, engaging in trade, raids, and sieges—though only against "infidel" populations.  

According to historical accounts, Sigurd’s journey began with peaceful interactions with English and French Christians. However, he soon encountered conflict in Galicia, where he fought a local count, and later engaged in a naval battle with the Saracens in 1108. Victorious in both encounters, Sigurd gained wealth and glory, attributed to his faith and courage. After successfully besieging and capturing the wealthy city of Lisbon, Sigurd sailed directly to the port of Ascalon, where he was welcomed with honor by King Baldwin I of Jerusalem. Baldwin accompanied Sigurd on a pilgrimage to the holy sites, requesting that the Norwegian king enact religious reforms in Norway—reforms that would not be implemented until 1152, highlighting the dual spiritual and material motivations of Sigurd’s journey.  

In 1110, Sigurd agreed to fight alongside Baldwin against the city of Sidon, contributing significantly to its conquest and demonstrating his military prowess. With his pilgrimage and expedition deemed complete, Sigurd returned to Norway in 1111, bringing with him fame and wealth. He would later be known as "the Crusader."
