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 Cruises
The company was established by Torstein Hagen in Leningrad as Viking River Cruises in 1997. Hagen had become involved in cruising as a McKinsey and Co. consultant who helped the Holland America Line survive the 1973 oil crisis, then was briefly CEO of Royal Viking Line in the early 1980s, made money in the Russian private equity markets, then bought a controlling stake in a Dutch shipping company that failed in the mid-1990s, leaving him almost bankrupt. Around that time he helped some Russian oligarchs buy a shipping company, and in exchange they sold him four river cruise ships cheaply, which were the founding fleet of Viking.
