Book excerpt: This encyclopedia covers American right-wing extremist groups and extremism from the 1930s to the present day, including neo-Nazis, the Ku Klux Klan, and various anti-government organizations. Right-wing extremism in America has had an established presence from the 1930s through the present day. The election of America's first African-American president and the resuscitation of "big government" policymaking have stimulated a reaction from, and a reemergence of, right-wing extremists, Neo-Nazis, racist skinheads, and white supremacists. Unfortunately, it seems Americans are still living in an age of extremism. The Encyclopedia of Right-Wing Extremism in Modern American History provides useful, authoritative information about these groups and their histories, covering conservative extremism from the 1930s onward, such as white supremacist groups and neo-Nazis, Christian Identity and other right-wing religious movements, and anti-American government extremists. An introductory overview, insightful conclusion chapter, and useful, up-to-date bibliography are also included.
