Salazar (I)

dictatorship
In modern usage, absolute rule unrestricted by law, constitution, or other political, or social factors within the state.

Thei power was neither arbitrary nor unaccoutable, being subject to law and retrospective justification (...).

In the twentieth century the existence of dictator has been a necessary (and to some) a defintive component of totalitarian regimes (...).
