Was the John Wilkes Booth conspiracy the "anti-John Brown conspiracy" or the "counter-John Brown" actions within the U.S. 19th century conflict that "started" in bleeding Kansas and ended in the fratricide of the U.S. Civil War and Reconstruction-era terror?
Carola Dietze, translated from the German by David Antal, James Bell and Zachary Murphy King, The Invention of Terrorism in Europe, Russia and the United States (Verso, 2021), argued that there were five men who "founded" modern terrorism between 1858 and 1866:
--Felice Orsini, who attempted to assassinate Napoleon III in 1858
--John Brown, who attacked the Harpers Ferry U.S. arsenal to start an insurrectionary servile war in the slave states in 1859
--Oskar Wilhelm Becker, who tried to assassinate Koenig Wilhelm I of Prussia in 1861
--John Wilkes Booth, who murdered Abraham Lincoln, POTUS in 1865
--Dmitry Vladomirovich Karakozov, who tried to kill Czar Alexander II in 1866 [Ultimately, he was blown up with nitroglycerine by the Narodnaya Volya or "peoples will" on 13 Mar. 1881...]
