Ken Yellis, writing in "The Forward", has suggested that "the majority of American Jews were mute on the subject, perhaps because they dreaded its tremendous corrosive power. Prior to 1861, there are virtually no instances of rabbinical sermons on slavery, probably due to fear that the controversy would trigger a sectional conflict in which Jewish families would be arrayed on opposite sides. ... America's largest Jewish community, New York's Jews, were overwhelmingly pro-southern, pro-slavery, and anti-Lincoln in the early years of the war." However, as the war progressed, "and the North's military victories mounted, feelings began to shift toward ... the Union and eventually, emancipation."
