From neo-Nazis to Trotsky: 20th century political extremism

2 March 2020

Until 1 April 2020 students and staff of Leiden University have trial access to the digital primary source collection called Political extremism and radicalism: Far-right and left political groups in the U.S., Europe, and Australia in the twentieth century of Gale Cengage.

The collection draws on a range of archives from the US and UK on far-right and fascist movements, alongside various radical left groups, containing information on prominent groups such as the Klu Klux Klan, the Black Panthers, National Socialist Party of Australia, and the British Union of Fascists as well as leading figures including Oswald Mosley, Arnold Leese, Vladimir Lenin and Leon Trotsky.   Its scope also covers areas of focused interest, including gay activism, anti-Semitic and neo-Nazi groups, equal rights, environmentalism, and creationism among others.

Researchers in contemporary topics will also find value in the content, allowing them to explore the origins and development of present-day issues, including anti-war thinking, ‘fake news’, the resurgence in right-wing politics, and radicalisation.


The Political Extremism-collection is available until 1 April 2020.

Access is via: Catalogue Leiden University > tab Find Databases > Political extremism & radicalism in the twentieth century.
