Self-coup

A self-coup (or autocoup) is a form of putsch or coup d'état in which a nation's leader, despite having come to power through legal means, dissolves or renders powerless the national legislature and unlawfully assumes extraordinary powers, not granted under normal circumstances. Other measures taken may include annulling the nation's constitution and suspending civil courts. In most cases the head of government becomes a dictator.

List of self-coups

 * Ancient Rome: The Roman dictatorship was an established form of office during the Republican period, in which one person (a consul or ex-consul), during an emergency, had absolute power for six months. Lucius Cornelius Sulla and Julius Caesar, however, had dictatorship for a longer time; Caesar was named dictator perpetuo, or dictator-for-life, and was subsequently assassinated shortly after accepting this position.
