Historians have long debated the extent of antisemitism in America's past and contrasted American antisemitism with its European counterpart. Earlier students of American Jewish life minimized the presence of antisemitism in the United States, which they viewed as a late and alien phenomenon on the American scene arising in the late 19th century. More recently, scholars have asserted that no period in American Jewish history was free of antisemitism. The debate continues about the significance of antisemitism in different periods of American history.
