History of slavery - Wikipedia the free encyclopediaFrom the 1440s into the 18th century, as many as 1.5 million white Europeans from Italy, Spain, Portugal, France and EnglandUkrainians were sold into slavery by North Africans.[44] In 1575, the Tatars captured over 35,000 Ukrainians; a 1676 raid took almost 40,000. About 60,000 Ukrainians were captured in 1688; some were ransomed, but most were sold into slavery.[45][46] Some of the Roma people were enslaved over five centuries in Romania until abolition in 1864 (see Slavery in Romania).[47]
Muslims continued to trade in European slaves into the Modern time-period.[43] Muslim pirates, primarily Algerians with the support of the Ottoman Empire, raided European coasts and shipping from the 16th to the 19th centuries, and took thousands of captives, whom they sold or enslaved. Many were held for ransom, and European communities raised funds to buy back their citizens. The raids gradually ended with the naval decline of the Ottoman Empire in the late 16th and 17th centuries, as well as the European conquest of North Africa throughout the 19th century.[43] The United States conducted a war in North Africa to defeat the Barbary Pirates in its early Federal period, 1803-05. State piracy of the North African Arab states continued until France colonized Algeria in 1835.
Oh God, again Wikipedia. I have took a look your Wikipedia and it bases its claims on a few books but I cant read any of them ? So how I would discuss about the issue ? Your claim has no available sources, there are a few book names without any online links to read them and their own sources ?
We also say ISIS was created by intelligence agencies but noone cares about it on the pretext of "there are no links proven."
So, the same goes for here, please provide various sources to me ? or you are lying.
I provided that link as a starting point for you. Feel free to research it more in depth. It's not my job to educate you. Your ignorance does not make those who know about history liars.
Based on your reaction I think it is safe to say you have no interest in finding out the truth about Islamic history. Just because our history classes didn't address Islamic conquest doesn't mean it didn't happen.
