This SpringerBrief is an extension of the article "Parallelization: the fourth leg of cultural globalization theory" (Integrative Psychological and Behavioral Science, 2021) by Dr. Björn Boman. The original article consisted of four main examples of parallelization, and has been expanded to include chapters on Korea, Russia-Ukraine, and Georgia. This book points to the relations between oppositely directed processes and the need for theoretical modelling of complex societal processes.
