Answer:
Monarchy, Oligarchy, Theocracy, Authoritarianism, and Totalitarianism.
Step-by-step explanation:
Monarchy - Rule of one. It was traditionally a king or emperor ruling, but in modern times this usually describes a dictator.
Oligarchy - Rule of the few. Traditionally, this described a group of aristocrats, men of noble blood. But is easily describes a group of warlords or a military junta.
Theocracy - Rule by God. Since God rarely shows up to manage the day-to-day affairs of government, this involves rule by a religious leader or group of religious officials who interpret God's will.
Authoritarianism - Monopoly of political power by an individual/small group that allows people to go about their private lives as they wish.
Totalitarianism - Rule by an elite who exercises unlimited power over individuals in all aspects of life.
