"Might makes right" or "might is right" is an aphorism that asserts that having superior strength or power gives one the ability to control society and enforce one's own agenda, beliefs, concepts of justice, and so on. Montague defined kratocracy or kraterocracy (from the Ancient Greek: κράτος, romanized: krátos, lit. 'might; strength') as a government by those strong enough to seize control through violence or deceit.
"Might makes right" has been described as the credo of totalitarian regimes. The sociologist Max Weber analyzed the relations between a state's power and its moral authority in Wirtschaft und Gesellschaft. Realist scholars of international politics use the phrase to describe the "state of nature" in which power determines the relations among sovereign states.
