In 1919 Woodrow Wilson appointed A. Mitchell Palmer as his attorney general. Palmer recruited John Edgar Hoover as his special assistant and together they used the Espionage Act (1917) and the Sedition Act (1918) to launch a campaign against radicals and left-wing organizations.
Worried by the revolution that had taken place in Russia, Palmer became convinced that Communist agents were planning to overthrow the American government. His view was reinforced by the discovery of thirty-eight bombs sent to leading politicians and the Italian anarchist who blew himself up outside Palmer's Washington home. Palmer recruited John Edgar Hoover as his special assistant and together they used the Espionage Act (1917) and the Sedition Act (1918) to launch a campaign against radicals and left-wing organizations.
A. Mitchell Palmer claimed that Communist agents from Russia were planning to overthrow the American government. On 7th November, 1919, the second anniversary of the Russian Revolution, over 10,000 suspected communists and anarchists were arrested. Palmer and Hoover found no evidence of a proposed revolution but large number of these suspects were held without trial for a long time. The vast majority were eventually released but Emma Goldman and 247 other people, were deported to Russia.
On 2nd January, 1920, another 6,000 were arrested and held without trial. These raids took place in several cities and became known as the Palmer Raids. A. Mitchell Palmer and John Edgar Hoover found no evidence of a proposed revolution but large number of these suspects, many of them members of the Industrial Workers of the World (IWW), continued to be held without trial. When Palmer announced that the communist revolution was likely to take place on 1st May, mass panic took place. In New York, five elected Socialists were expelled from the legislature.
When the May revolution failed to materialize, attitudes towards Palmer began to change and he was criticised for disregarding people's basic civil liberties. Some of his opponents claimed that Palmer had devised this Red Scare to help him become the Democratic presidential candidate in 1920.
