As a result the Muscovite Empire soon found within its precincts a strangely composed Jewish population, consisting of prisoners of war, who had been carried off principally from the border towns of the Government of Moghilev, and had been deported to the central provinces of Russia, and in some cases even as far as Siberia. By the Peace of Andrusovo, concluded in 1667 between Russia and Poland, the prisoners of war of both countries were given their freedom, but the captive Jews were allowed to remain in Muscovy. These Jews formed the nucleus of a small Jewish colony in Moscow, which grew up gradually, and in which occasionally even converts were to be found. It seems that with the aid of these "legal" Jewish residents other "illegal" Jews, from the neighboring regions of Lithuania and White Russia, managed to penetrate to Moscow. A few Jewish merchants, particularly those trading in cloth, succeeded in obtaining an official permit, the so-called "red ticket," to visit the capital. However, in 1676 the prohibition against Jews entering Moscow was renewed. Only in the portion of the Ukraina which had been annexed by Russia, in the provinces of Chernigov and Poltava, and a part of the province of Kiev, there could still be found small groups of Jews who had survived the Cossack massacres of 1648. Moreover, from the Polish section of the Ukraina, Jews occasionally came on business into these Cossack districts, notwithstanding the fact that, according to Russian law, the Jews were barred from residing within the borders of Little Russia. 2. THE JEWS UNDER PETER I. AND HIS SUCCESSORS This treatment of the Jews did not improve even in the new Russia, in which Peter the Great, the Tzar-Reformer, "had broken through a window into Europe." True, Peter's reforms effected a change for the better in the attitude of the isolated, unenlightened Empire towards foreigners, but this change did not extend to the Jews. We know of no laws enacted during his reign which might illustrate the views of the new Government on the Jewish question. There is reason to believe that the Tzar, in allowing the former enactments against the admission of Jews into Russia to remain in force, took into account the primitive habits and prejudices of his people. A contemporary witness narrates that, in 1698, during Peter's stay in Holland, the Jews of Amsterdam requested the burgomaster Witsen to petition the Tzar concerning the admission of their coreligionists into Russia. After listening to the convincing arguments of Witsen, with whom he was on a very friendly footing, Peter replied:
