How a failed May Day prophecy ended the first American Red Scare
In short: Following World War I, the United States gripped by fear of a Bolshevik revolution. Attorney General A. Mitchell Palmer launched aggressive raids to purge radical leftists, deporting hundreds. Yet, when his dire predictions of a violent uprising on May Day 1920 failed to materialize, the entire movement collapsed under public scrutiny.
The first Red Scare emerged from the post-war climate of 1917 to 1920, fueled by the Russian Revolution and domestic instability. Americans faced rampant inflation, unemployment, and violent labor strikes, such as the 1919 Seattle General Strike. This anxiety intensified after a series of anarchist mail bomb plots in 1919, including an attack that destroyed Attorney General A. Mitchell Palmer’s home. Seeking to establish himself as a law-and-order presidential candidate, Palmer collaborated with J. Edgar Hoover to create the General Intelligence Division within the FBI.
The resulting Palmer Raids targeted foreign anarchists, communists, and radicals. In November 1919, authorities raided the Union of Russian Workers, and by December, 249 individuals—including Emma Goldman—were deported on the USS Buford. The campaign reached its peak on January 2, 1920, when thousands were arrested across more than 30 cities. These operations often bypassed legal requirements, with many detainees held simply for having foreign accents. Palmer claimed that over 300,000 dangerous communists remained in the country, justifying his aggressive tactics as essential for national security.
However, the tide of public opinion shifted as the brutality of the raids became clear. Critics, including the National Civil Liberties Bureau, challenged the constitutionality of the government's actions. Furthermore, Acting Secretary of Labor Louis Post reversed over 70 percent of the 1,600 deportation warrants issued during the period. The final blow to Palmer’s credibility came on May 1, 1920. Despite warnings from J. Edgar Hoover of a bloody revolution, the day passed without incident. This failure, combined with growing legal and public opposition, effectively ended the Palmer Raids and brought the first Red Scare to a close.
The era left a lasting mark on American policy, with Congress passing restrictive measures like the Immigration Act of 1918, which specifically targeted anarchists. While the scare was driven by genuine fears of foreign influence and radicalism, it ultimately demonstrated the fragility of civil liberties during times of national hysteria. By the time the dust settled, the government’s overreach had alienated the public, proving that even the most intense political panics can evaporate when their foundational predictions fail to manifest.
