Another rise began in 1899. Economic depression, revolutionary terrorism and anti-Jewish propaganda paved the way for a great inpouring of Russian Jews to the United States. The Kishineff massacre of 1903 sent thousands of Jews in veritable flight to the United States, a fact which is reflected in an immigration of 77,544 Russian Jews in 1904, the greatest number up to this year. With the beginning of the Russo-Japanese war, the outbreak of the revolution and, above all, of the Jewish massacres the immigration rose in 1905 to 92,388. In 1906, a year of _pogroms_, it reached the number of 125,234, the highest in the entire period--and in 1907, 114,932, the second largest immigration. The diminution in the numbers in 1908 reflects largely the relative change for the better that took place in the situation in Russia, with the beginning of parliamentary government, as well as the panic conditions in the United States of the preceding year. How great still was the impulse to leave is shown by the fact that in spite of the panic of 1907, the number of immigrants for 1908 was 71,978. The great rise of the immigration from the United Kingdom during these years was also due to the number of Russian Jews that came to the United States by way of England. In all, during these five years which form an epoch in contemporary Russian Jewish history, there streamed into the United States half a million Russian Jews, constituting more than two-fifths of the total immigration for the entire thirty years. Of special significance is the part the Jewish immigrants play in the total Russian immigration to the United States.[67] By far the largest group of immigrants coming from Russia are Jews. For the entire thirty years they constituted 48.3 per cent of the total Russian immigration. As a general rule, the proportion of the Jewish in the total Russian immigration rises during the critical periods of these thirty years. Thus in 1891, the year of the Moscow expulsions, the Jewish immigrants constituted 91.6 per cent of the total immigration from Russia, and in the following year, under the same influences, 78.8 per cent. The years 1886 and 1887 are also signalized by the great proportion of the Jewish immigrants, who formed 79.2 per cent and 75.1 per cent, respectively, of the total Russian immigration for these years. In the last decade, when the Jewish participation in the total immigration had become relatively lessened, the three years which represented the climax of the movement, 1904, 1905 and 1906, show a higher relative proportion, 53.4 per cent, 50 per cent and 58.1 per cent, respectively, than the average for the decade or for the entire period.
