This book will analyze several revolutions of the long nineteenth and short twentieth century to show how revolutionary processes evolved. It will therefore use a comparative ten-step model to emphasize similarities with regard to the revolutionary developments in different parts of the world. The book consequently aims at providing a general, but deeper, understanding of revolutions as a global phenomenon of modernity while explaining how revolutionary processes evolve and develop, and how they could and can be corrupted. The revolutionary case studies discussed will include, among others, France, Russia, Mexico, and China.
