The Fascist League of North America (FLNA) was an umbrella group for fascist Italian-American organizations that was active from 1924 to 1929. The FLNA brought together 40 grassroots fascist clubs formed in Italian communities across the United States, and the National Fascist Party exercised its suzerainty over the American branches of the party in the late 1920s, with Theon di Revel organizing the Fasci into the FLNA. The Italian diplomatic corps was worried about the FLNA's activities sabotaging American public opinion of Italian fascism, and its supporters clashed with the liberals, socialists, communists, and anarchists of the Anti-Fascist Alliance of North America from 1923 into the 1930s; at least a dozen were killed. The FLNA received the backing of Domenico Trombetta's Il Grido della Stirpe in New York City, Francesco Macaluso's Giovinezza in Boston, and Generoso Pope's faction of the Democratic Tammany Hall political machine.
The United States Department of State initially viewed the FLNA as a group committed to law and order and anti-communism and saw no reason to ask for its disestablishment, but a November 1929 Harper's Magazine article on the FLNA's supposed plot to control the Italian community in the United States led the Italian diplomatic corps to shut down the FLNA.
