What are events in history that are similar to the Red Scare? (give details/reasons why please!)

A shorter but more intense Red Scare occurred late in 1919 after a few anarchist bombings in the US, including in DC. Midnight bombs in 8 cities led to a summer long “red scare” of pro-patriotism and intense fear of dissent from the left. Finally, Attorney General A. Mitchell Palmer implemented mass raids of so-called radicals. The raids were planned and coordinated by a young Justice Department employee named J. Edgar Hoover. Thousands of people were rounded up in union halls, meeting rooms, political meetings. All were on the left but only a handful were genuine communists or anarchists. Still, without trial, 247 people were deported, many sent directly to the new Soviet Union. The Palmer Raids, as they are still called, were only stopped when courageous officials in the government began denouncing the campaign of fear and deportation.
