Between the early 1880s and the first world war, around two million Jews left Russia, Romania, parts of the Austria-Hungarian Empire, and went westward. Of this large outflow, a minority settled in England about a 140, a 150,000 settled in England. Many more spent a few days or a few years in England on their way to the United States or perhaps to South America. In England, London was the greatest center of settlement. By 1900, there were perhaps a 140,000 Jews. The combination of immigration and urban growth once again led people to ask the question, in what ways are Jews different, and in what ways are they similar? So this fed into some of the opposition to Jewish immigration. One of the leading opponents of Jewish immigration was someone who William Evans-Gordon, someone who interestingly had a very friendly correspondence with Chaim Weitzman, but leaving that on one side. Gordon was like many others believed that urban conditions lead to a degeneration as people put it of the quality of human being. Rural conditions were seen to be natural, urban conditions as unnatural. The overwork, the overcrowded conditions, the insanitary conditions were all seen to lead to degeneration, which was then passed on to subsequent generations it was thought. But yet, here with these Jewish immigrants, said Evans-Gordon, who were thriving in urban conditions in London, and in his view, how could he answer this problem? It was because he thought that in degenerating conditions, only a degenerate social type would thrive and persist. So in this way, the combination of Jewish immigration and urbanism lead to new thinking about forms of Jewish difference.
