This work investigates whether the political and social upheavals in England between 1640 and 1660 constitute a mere rebellion against monarchical authority or a fundamental revolution of the state. G. E. Aylmer, a noted historian of the Stuart period, synthesizes the historiographical debates surrounding the English Civil War. He evaluates the transition from monarchy to republicanism by examining the shifting interpretations of contemporary scholars regarding the structural causes and long-term consequences of the era.
