Reply To: An ancient Jewish Kehilah in Turkey – since around 3,460 – ceased to exist this

First of all, you’re off by 1000 years – you probably meant 2460.
Second, jews today there are Sphardic, not native Antochians. The natives were killed / expelled by the Christians in the late 300’s. They mostly moved further west (Italy etc..) where the persecution of the church was less. The expelled Byzantine jews founded / joined early European communities. They wrote the Yotzros / Piyutim that Ashkenazim use to this day.
