Many here claim that the Jews who migrated to the region known as "Palestine" starting in the late 19th century claim that they are an invented people and have no ties to Israel at all. They all follow the theory that they are all converts from the country of Khazar to Judaism.

However, that theory has been debunked or at the very least been shown to be just a theory.
Here is a couple of much more plausible timelines:
History of the Jews in Europe - Wikipedia the free encyclopedia
Jews in the Middle Ages - Wikipedia the free encyclopedia
Both of these mention the Ashkenazi, however the second one follows that they migrated to that area due persectution. I will not quote either of the two articles, I hope you read them before commenting, but another thing of note is in the second article, the Ottomans did help the Jews to migrate to the Ottoman empire.
