I am not an expert, but I think most people begin the timing in 1492, when the Turks (I think it was Suleiman I) invited the Jews expelled from Spain by Isabella The Catholic to seek refuge in Turkey.
Almost singularly so, there was no oppression of that small community since then: no oppressive legislation singling out the Jews, no pogroms from the public.
Let us not forget that both Jews and Moslems were expelled from Spain in 1492. The Moslems and Jews had colloborated in the oppression of the native Spanish Christian population. No one seems to understand this. The Jews colloborated with the Turks in the enslavement of the Christians in the Balkans. Can anyone seriously deny this? Remember that the Turks also murdered up to 2 million Armenian Christians during World War I. They have never owned up to that fact. British prisoners captured at Kut during the Great War in what is now Iraq were subjected to the most horrible war crimes imaginable. Many were raped by their Turkish captors. Let the truth be known by all.
