A government ruled by ten people or a state divided into ten districts.
From Greek 'deka-' (ten) and '-archy' (rule or government), literally 'rule by ten.' This learned word combines classical Greek elements used in political theory.
Ancient philosophers obsessed over the 'perfect' number of rulers—one, few, or many—so they invented words like this for every possibility, even ones that never actually existed in the real world.
