A revolutionary government is a type of political system that emerges after a significant change in power, often following a revolution. This government typically arises when a group seeks to overthrow an existing regime, aiming to implement new policies and ideologies. The changes can be driven by social, economic, or political dissatisfaction among the populace. Revolutionary governments may adopt various forms, such as a dictatorship, democracy, or military rule, depending on the leaders and their goals. Historical examples include the French Revolution and the Russian Revolution, where new governments sought to reshape society according to their revolutionary ideals.
