Describing a system of government where one person has absolute power, or describing a country that is self-sufficient and doesn't depend on others.
From 'autarch' plus the suffix -ic meaning 'of or relating to.' It can mean both authoritarian rule and economic self-sufficiency (autarky).
Countries with autarchic governments tend to also try to be autarchic economically—North Korea is a modern example, trying to be completely independent and ruled by one family!
