Eastern Europeans dislike Islam for a lot of reasons most Americans never learn about in high school or college history classes — here is Raymond Ibrahim:
Why Eastern Europeans are much more reluctant to accept Muslim migrants than their Western counterparts can be traced back to circumstances surrounding a pivotal battle, that of Kosovo, which took place today, June 15, exactly 630 years ago today in 1389. It pitted Muslim invaders against Eastern European defenders, or the ancestors of those many Eastern Europeans today who are resistant to Islam.
Because the jihad is as old as Islam, it has been championed by diverse peoples throughout the centuries — Arabs in the Middle East, Moors (Berbers and Africans) in Spain and Western Europe, etc. Islam’s successful entry into Eastern Europe was spearheaded by the Turks, specifically that tribe centered in westernmost Anatolia (or Asia Minor) and thus nearest to Europe, the Ottoman Turks, so-named after their founder, Osman Bey. As he lay dying in 1323, his parting words to his son and successor, Orhan, were for him “to propagate Islam by your arms.”
This his son certainly did; the traveler Ibn Batutua, who once met Orhan in Bursa, observed that although the jihadi had captured some one hundred Byzantine fortresses, “he had never stayed for a whole month in any one town,” because he “fights with the infidels continually and keeps them under siege.” Christian cities fell like dominoes: Smyrna in 1329, Nicaea in 1331, and Nicomedia in 1337. By 1340, the whole of northwest Anatolia was under Turkic control. By now and to quote a European contemporary, “the foes of the cross, and the killers of the Christian people, that is, the Turks, [were] separated from Constantinople by a channel of three or four miles.”
By 1354, the Ottoman Turks, under Orhan’s son, Suleiman, managed to cross over the Dardanelles and into the abandoned fortress town of Gallipoli, thereby establishing their first foothold in Europe: “Where there were churches he destroyed them or converted them to mosques,” writes an Ottoman chronicler. “Where there were bells, Suleiman broke them up and cast them into fires. Thus, in place of bells there were now muezzins.”
