This book is a comparative case study in the historical sociology of modern social restorations. This is a new field in comparative social research designed to extend and complete comparative historical sociological research on social revolutions. Comparative research on revolutions is a well-established research field, as at least four generations of theory have changed to date (cf. Goldstone 2001, 2014; DeFronzo 2006, 2021). It originated with the comparison of 1789 French and 1917 Russian revolutions (Shlapentokh 1999), culminating in the famous study by Theda Skocpol (1979), which is one of the most influential and cited works in comparative social research (Goodwin 1996). Puzzlingly, as yet no authors have taken into due account the fact that both great modern social revolutions did in fact end (in 1815 and 1989 correspondingly) with restorations of the prerevolutionary regimes.
