Primary Sources supporting research into extremist and radical groups

Liberal democracies of North America, Europe, and Australasia throughout the twentieth century have experienced a variety of forms of extremism and radicalism that have shaped mainstream political thinking as well as cultural norms. To comprehend modern governmental and societal systems researchers must understand the environment that created them, their origins, and their adversaries. In the series Political Extremism and Radicalism, Gale provides insight on unorthodox (by contemporary standards), fringe groups from both the right and left of the political spectrum through rare, hard to access primary sources. Content supports scholars and students answering questions on philosophical, social, political, and economic ideologies as well as on contemporary issues surrounding gender, sexuality, race, religion, civil rights, universal suffrage, and much more.
