A form of government or rule by two people, powers, or groups holding equal authority.
From Greek 'di-' (two) + 'archia' (rule, government). Related to diarchy. Archaic political term from ancient and medieval political philosophy.
Rome briefly tried dinarchy with two consuls checking each other's power—it was their genius invention, yet the word 'dinarchy' itself is nearly forgotten, replaced by 'dual leadership' and 'co-rule.'
