Why “isopolity” is a great word
ISOPOLITY — [Noun] A reciprocal treaty conferring equal civic and political rights between distinct city-states, creating a shared, portable citizenship while preserving separate sovereignties. From Ancient Greek ἰσοπολιτεία (isopoliteía), from ἴσος (ísos, "equal, same") + πολίτης (polítēs, "citizen"). Unlike sympolity, which dissolves politics into a formal federation, or asylum, which offers only a one-way sanctuary, isopolity is a mutual covenant of belonging without conquest. It is the weight of a foreign voting token in your hand, the standing to plead in an agora far from your birth, and the legal fiction that a man from Miletus could be, for all purposes, a citizen of Ephesus—a compact against the tyranny of geography and a civilized dream that one might be at home in more than one place.
