That Russo-Poland should have elected a Jewish king on two occasions, a
certain Abraham Prochovnik in 842 and the famous Saul Wahl[9] in the
sixteenth century, sounds legendary; but that there was a Jewish queen,
called Esterka, is probable, and that some Jews attained to political
eminence is beyond reasonable doubt.[10] Records have been discovered
concerning two envoys, Saul and Joseph, who served the Slavonic czar
about 960, and an interesting story is told of two Jewish soldiers,
Ephraim Moisievich and Anbal the Jassin, who won the confidence of
Prince Andrey Bogolyubsky of Kiev, and afterwards became leaders in a
conspiracy against him (1174).[11] Henry, Duke of Anjou, the successor
of Sigismud August on the throne of Poland and Lithuania, owed his
election mainly to the efforts of Solomon Ashkenazi. Ivan Vassilyevich,
too, had many and important relations with Jews, and his favorable
attitude towards them is amply proved by the fact that his family
physician was the Jew Leo (1490). Throughout his reign he maintained an
uninterrupted friendship with Chozi Kokos, a Jew of the Crimea, and he
did not hesitate to offer hospitality and protection to Zacharias de
Guizolfi, though the latter was not in a position to reciprocate such
favors.[12]

In addition there are less prominent individuals who received honors at
the hands of their non-Jewish countrymen. Meïr Ashkenazi of Kaffa, in
the Crimea, who was slain by pirates on a trip from "Gava to Dakhel,"
was envoy of the khan of the Tatars to the king of Poland in the
sixteenth century. Mention is made of "Jewish Cossacks," who
distinguished themselves on the field of battle, and were elevated to
the rank of major and colonel.[13] While the common opinion regarding
Jews expressed itself in merry England in such ballads as "The Jewish
Dochter," and "Gernutus, the Jew of Venice," many a Little Russian song
