Parallelism is a theory of social processes. It represents an attempt at systematizing historical events. Other scholars have sought to employ similar approaches and methods. This has led in political science to the development of a series of theories and classificatory schemas for revolutions, wars, political systems, etc. The parallelistic approach assumes that such processes can not only be understood but manifestly justified and exposed through the use of predictive power. Currently this approach has identified two macro-historical patterns. The first is Revolution Pattern Type A, the second, Paternalistic Regime/Hegemonic War Pattern Type A.
