Some claim that Jews lived in a virtual paradise under Islamic rulers in North Africa and the Middle East. Some claim that Jews and Muslims have lived peacefully side-by-side since the spread of Islam by sword. The "benevolence" of Muslims toward their non-Muslim neighbors included such things as making Jews wear yellow badges and Christians blue ones. Jews were forced to live in ghettos. Non-Muslims lived at the whim of mobs. They faced pogroms which were as devastating as any seen in Eastern European countries. The Meccan army slaughtered Jews in 665ad. The "benevolence" continues to this day.
Much like early Christians, Mohammed was infuriated that Jews refused to accept the teachings of Mohammed. The Koran describes Jews in such glowing terms as the descendants of pigs and apes. Anti-semitism runs rampant in Arab Muslim countries. There are those that will try to explain this hatred resulted from Zionism and the establishment of the Jewish State of Israel. This flies in the face of historic facts.
Solomonia has a great round-up of books in which Jews lived under the "benevolence" of Muslims for the past 1,400 years.
