The rule or government of devils; a system controlled by demonic or devilish forces.
From diabolos (devil) + -archy (rule, government). Related to diabolarch, created in theological and literary contexts.
Diabolarchy was probably coined in medieval or Renaissance theology to describe what happens when evil rules a place—but the word itself has almost no historical usage, existing mostly as a theoretical opposite to monarchy or theocracy.
