Answer:
The form of government you are referring to is called
dictatorship.
Step-by-step explanation:
It is a form of government in which a ruler or small clique wield absolute power (not restricted by a constitution or laws) and individuals have no right and the government suppresses all opposition.
Other forms of government include autocracy, which is a form of government in which one ruler has absolute control and decision-making power, and absolutism, which is the political doctrine and practice of unlimited centralized authority and absolute sovereignty, as vested especially in a monarch or dictator.
