From AD 839, Viking Varangian mercenaries who were in the service of the Byzantine Empire, notably Harald Sigurdsson, campaigned in North Africa, Jerusalem and other places in the Middle East during the Byzantine-Arab Wars. They interbred with the local population as spoils of warfare or through eventual settling with many Scandinavian Viking men taking Arab or Anatolian women as wives. There is archaeological evidence the Vikings had established contact with the city of Baghdad, at the time the center of the Islamic Empire, and connected with the populace there. Regularly plying the Volga with their trade goods (furs, tusks, seal fat, seal boats and notably female slaves; the one period in the history of the slave-trade when females were priced higher than males), the Vikings were active in the Arab slave trade at the time. These slaves, most often Europeans that were captured from the coasts of Europe or during war periods, and sold to Arabic traders in Al-Andalus and the Emirate of Sicily.
Viking FK
Viking was founded in Stavanger in 1899 and played mainly local games in the early years. From the 1930s, the club established itself at the national level, playing in the 1933 cup final, which it lost to Mjøndalen. During the 1930s the club produced several of its best known players, most prominently Reidar Kvammen, who played in Norway's bronze medal winning 1936 olympic team. His brother Arthur Kvammen was also capped for Norway, while Bernhard Lund later went on to write the club anthem.
