Apocalyptic (end times) beliefs are found across different religious cultures and time periods, especially those influenced by the Abrahamic faiths. These apocalyptic beliefs are often associated with radicalized politics and what we would today often describe as "populist" movements and leaders. What are the roots of such beliefs? How have they developed over time? In what ways do they impact the modern world? In a series of case studies—ranging over different faiths, time periods, and global locations—this book explores how and why these beliefs have become so often the driver of radicalized politics.
