antisemitism has increased in the Muslim world during modern times, there is no doubt about that. but this increase in anti jews has risen ten fold simply due to the establishment of
Israel.
European influence has to be given the blame for this, including that of Nazis and the establishment of Israel as the root causes for antisemitism. also that increased European commercial, missionary and imperialist activities during the 19th and 20th centuries brought anti-Semitic ideas to the Muslim world. Initially these prejudices only found a reception among Arab Christians and were too foreign for any widespread acceptance among Muslims. However, with the rise of the arab-israeli conflict, the anti-jewish has simply ran accross most of the muslim world from north africa to indonesia.
