centuries the usage broadened into a spectrum of meaning cited by the larger Latin dictionaries: it could mean in addition to the citizenship established by the constitution the legal city-state, or res publica, the populus of that res publica (not people as people but people as citizens), any city state either proper or state-like, even ideal, or (mainly under the empire) the physical city, or urbs. Under that last meaning some places took on the name, civitas, or incorporated it into their name, with the later civita or civida as reflexes.
