That's kind of difficult, seeing as how 1200 AD is after
I assume you meant no earlier then 700 BC and no later then 1200 AD? In any case, having the Jewish Khazars survive and even thrive could work.
Or have medieval Christians have less of a "CONVERT OR DIE" mindset regarding the Jews. Maybe a writing by an early Christian author that is pro-Jewish?
