noun, plural kak·is·toc·ra·cies.
- government by the worst persons; a form of government in which the worst persons are in power.
1829, “government by the worst element of a society,” coined on analogy of its opposite, aristocracy, from Greek kakistos “worst,” superlative of kakos “bad” (which perhaps is related to the general IE word for “defecate;” see caco-) + -cracy.
