in Lithuania included Isaac b. Abraham of Troki (1543–1598), Joseph ben Mordecai Malinovski, Zera ben Nathan of Trakai, Salomon ben Aharon of Trakai, Ezra ben Nissan (died in 1666) and Josiah ben Judah (died after 1658). Some of the Karaim became quite wealthy. During the times of the Polish–Lithuanian Commonwealth, the Karaim suffered severely during the Khmelnytsky Uprising of 1648 and the wars between Russia and Commonwealth in the years 1654–1667. The many towns plundered and burnt included Derazhne and Trakai, where only 30 families were left in 1680. The destruction of the Karaite community in Derazhne in 1649 is described in a poem (both in Hebrew and Karaim) by a leader of the congregation, Hazzan Joseph ben Yeshuah HaMashbir. Catholic missionaries worked to convert the local Karaim to Christianity, but were largely unsuccessful. Russian Empire 19th century leaders of the Karaim, such as Sima Babovich and Avraham Firkovich, were driving forces behind a concerted effort to alter the status of the Karaite community in eyes of the Russian legal system. Firkovich in particular was adamant in his attempts to connect the Karaim with the Khazars, and has been accused of forging documents and inscriptions to back up his claims. Ultimately, the Tsarist government officially recognized the Karaim as being innocent of the death of Jesus. So they were exempt from many of the harsh restrictions placed on other Jews. They were, in essence, placed on equal legal footing with Crimean Tatars. The related Krymchak community, which was of similar ethnolinguistic background but which practiced rabbinical Judaism, continued to suffer under Tsarist anti-Jewish laws. Solomon Krym (1864–1936), a Crimean Karaite agronomist, was elected in 1906 to the First Duma (1906–1907) as a Kadet (National Democratic Party). On November 16, 1918 he became the Prime Minister of a short-lived Crimean Russian liberal, anti-separatist and anti-Soviet government also supported by the German army. Since the incorporation of Crimea into the Russian Empire the main center of the Qarays is the city of Yevpatoria. Their status under Russian imperial rule bore beneficial fruits for the Karaites decades later. During the Holocaust In 1934, the heads of the Karaite community in Berlin asked the Nazi authorities to exempt Karaites from the anti-Semitic regulations based on their legal status as Russians in Russia. The Reich Agency for the Investigation of Families determined that, from the standpoint of German law, the Karaites were not to be
