Who was oppressed in America during World War 1?

Answer 1

German Americans, IWW union members, Socialist groups, and anti-capitalists.

Throughout the 19th Century, socialist movements gained increasing support, championing the worker class over the autocracy. By 1871, the movement had split into two factions : anarchists and Marxists. After the failure of the 1905 Russian Revolution, socialist workers organizations consolidated into international groups with substantial membership. Although they ultimately failed to change the way industries operated in most Western governments, they succeeded finally in Russia with the Boshevik Revolution of 1917, which overthrew the Tsar's monarchy near the end of World War I.
