The Relationship Between Yemen and the Yerud

Yemen was a land where there were a lot of Christians in Jews, only Yemen. And the Yemeni Jews were the largest quantity of Jews in the Arabian Peninsula. One theory has it that the people from Jerusalem are wandering down and small pockets remain in Yathreb and the bulk goes to Yemen. The second theory is that they are the descendants of the Yemeni Jews. This makes complete sense as we're going to come to now.
