The Palmer Raids were a series of raids conducted in November 1919 and January 1920 by the United States Department of Justice under the administration of President Woodrow Wilson to capture and arrest suspected socialists, especially anarchists and communists, and deport them from the United States. The raids particularly targeted Italian immigrants and Eastern European Jewish immigrants with alleged leftist ties, with particular focus on Italian anarchists and immigrant leftist labor activists. The raids and arrests occurred under the leadership of Attorney General A. Mitchell Palmer, with 350,000 arrested. Though 556 foreign citizens were deported, including a number of prominent leftist leaders, Palmer's efforts were largely frustrated by officials at the U.S. Department of Labor, which had authority for deportations and objected to Palmer's methods. The Palmer Raids occurred in the larger context of the First Red Scare, a period of fear of and reaction against communists in the U.S. in the years immediately following World War I and the Russian Revolution. There were strikes that garnered national attention, and prompted race riots in more than 30 cities, as well as two sets of bombings in April and June 1919, including one bomb mailed to Palmer's home. Background During the First World War there was a nationwide campaign in the United States against the real and imagined divided political loyalties of immigrants and ethnic groups, who were feared to have too much loyalty for their nations of origin. In 1915, President Wilson warned against hyphenated Americans who, he charged, had "poured the poison of disloyalty into the very arteries of our national life." "Such creatures of passion, disloyalty and anarchy", Wilson continued, "must be crushed out". The Russian Revolutions of 1917 added special force to fear of labor agitators and partisans of ideologies like anarchism and communism. The general strike in Seattle in February 1919 represented a new development in labor unrest. The fears of Wilson and other government officials were confirmed when Galleanists—Italian immigrant followers of the anarchist Luigi Galleani—carried out a series of bombings in April and June 1919. At the end of April, some 30 Galleanist letter bombs had been mailed to a host of individuals, mostly prominent government officials and businessmen, but also law enforcement officials. Only a few reached their targets, and not all exploded when opened. Some people suffered injuries, including a housekeeper in Senator Thomas W. Hardwick's residence, who had her hands blown
