Establishing of Collegially Shared Power and Revolutions in Western Europe of XIX century

The article explores the approach to the study of socio-political crises based on the concept of collegially shared power (CSP). The results of the qualitative comparative analysis allow to distinguish five stages in the establishing of a high level of CSP: 1) a transition of power to a coalition government through a revolutionary coup; 2) a common rejection of practices of suppression of opponents due to the absence of a dominant actor; 3) lack of a new head’s of state sufficient resources to become an independent actor; presence of a common geopolitical threat; 5) maintaining a general parity of power.
