[1] The Jewish Encyclopedia gives some statistics on conversion of Jews to Protestantism, to Roman Catholicism, and to Orthodox Christianity[2] Some 2,000 European Jews converted to Christianity every year during the 19th century, but in the 1890s the number was running closer to 3,000 per year—1,000 in Austria Hungary (Galizian Poland), 1,000 in Russia (Poland, Belarus, Ukraine, and Lithuania), 500 in Germany (Posen), and the remainder in the English world.
[3] Data from the Pew Research Center that as of 2013, about 1.6 million adult Americans of Jewish background identify themselves as Christians, most are Protestant.
In England there was a large secession when individuals from the chief Sephardic families, the Bernals, Furtados, Ricardos, Disraelis, Ximenes, Lopez's, Uzziellis, and others, joined the Church (see Picciotto, "Sketches of Anglo-Jewish History").
In 1811, David Friedlander handed Prussian State Chancellor Hardenberg a list of 32 Jewish families and 18 unmarried Jews who had recently converted to Christianity (Rabbi Abraham Geiger, "Vor Hundert Jahren," Brunswick, 1899).
During this time the other German states, besides Austria and France, had an equal share in the number of those who obtained high stations and large revenues as the price for renouncing Judaism.
