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.
The Lost Vikings (series)
Their most recent appearance is as playable heroes in Blizzard's crossover multiplayer online battle arena video game, "Heroes of the Storm" (2015). Unlike other heroes in the game, who are played as a single unit, selecting the Lost Vikings gives the player control over all three Vikings, allowing them to control them as individuals or to issue commands to all three at once. Erik is faster than most other heroes, and attacks from range with a slingshot. Baleog has the greatest attack power of the three, and throws swords from a medium range, dealing area damage to enemies near his target. Olaf has the highest health pool, and recovers quickly when out of combat.
