"3. Anarchists banned
President Theodore Roosevelt. Signed on March 3, 1903. In 1903, the Anarchist Exclusion Act banned anarchists and others deemed to be political extremists from entering the US. In 1901, President William McKinley had been fatally shot by Leon Czolgosz, an American anarchist who was the son of Polish immigrants. The act - which was also known as the Immigration Act of 1903 - codified previous immigration law and, in addition to anarchists, added three other new classes of people who would be banned from entry: those with epilepsy, beggars and importers of prostitutes. The act marked the first time that individuals were banned for their political beliefs."
