Roger Griffin, Fascism: A Quick Immersion (New York: Tibidabo Publishing, 2020), ISBN 978-1-949845-12-9 For many years scholars were reluctant to study fascism and its ideology, preferring to place it in a quarantine box marked ‘conundrum’. Slowly, but thankfully, this has changed. However, unravelling the ideas that underpin fascism has remained one of the most difficult challenges for historians and political scientists in recent decades and, as Roger Griffin notes, ‘Fascism’ is evidently a contested and complex topic even today. Griffin’s new study seeks to unpack the complexities of rightwing ultra-nationalism for a wider audience, although specialists in the field will also find much of value in the book. Ever since his ground-breaking study The Nature of Fascism (1991) appeared, Griffin has devoted countless hours and much energy to the close analysis of rightwing extremism in all its forms and, in particular, to constructing a working definition of generic fascism, around which a fresh generation of scholars could find a new consensus. Famously, Griffin’s succinct formulation in 1991 stated: ‘Fascism is a political ideology whose mythic core in its various permutations is a palingenetic form of populist ultra-nationalism’. Much of his subsequent work provided further insights into this definition, and undoubtedly stimulated much scholarly debate - both for and against - which has continued to influence new academic research. Griffin’s latest publication, as he aptly notes, is a little book ‘but one dense with compressed arguments, theories and information’. Indeed, this publication is part of the ‘Quick Immersions’ series, a new initiative which seeks to provide ‘accurate and straightforward language’ to offer a good introduction or deeper knowledge on diverse issues in the social sciences and humanities. Griffin’s contribution more than succeeds in meeting these objectives, and also revisits his extensive work on rightwing extremism over the years. He explains and dissects his original definition and its subsequent evolution over time in a satisfyingly clear-cut fashion. The book is structured into four main chapters, together with a ‘Post-scripture’ and a brief but helpful guide to further reading. Griffin commences by responding to George Orwell’s well-known article ‘What is Fascism?’, published in 1944, which had expressed pessimism over whether a clear and generally accepted definition would
