The right or power of a region or state to govern itself independently; self-governance or autonomy.
From Greek 'autos' (self) + 'exousia' (power, authority). This is an extremely rare English term from philosophical and political texts discussing the concept of self-rule and sovereignty.
This word is so obscure that even many English dictionaries don't include it, yet it captures a central idea in political philosophy—the power to rule oneself—that nations have fought wars over.
