Abstract
This chapter examines fascism as a distinct form of ultra-nationalism, combining glorification of the nation with aggressive exclusion of those perceived as outsiders and even more enemies. It first considers the ‘era of fascism’ and the basic tenets of fascist ideology before discussing the various terminologies and classifications that have been used in order to analyse fascism and the radical right. It then explores the historical context in which fascism emerged as a radical ideology in twentieth-century Europe, seeking a ‘third way’ beyond liberalism and socialism. It also assesses fascism's overlaps with other established ideologies such as conservatism, authoritarianism, liberalism, and revolutionary socialism, along with the ensuing hybrids that it has spawned.
