In addition to the Roman curiae, voting assemblies known as curiae existed in other towns of Latium, and similar institutions existed in other parts of Italy.

The origin of this celebration is not certain, but many scholars feel that it may have been a ritualistic offering meant to appease and praise the Numa and that the 30 argei probably represented the thirty elder Roman curiae, or possibly represented the 30 Latin townships.

At least when the adopted person's status changed from patrician to plebeian or plebeian to patrician, the ceremony of adrogatio had to take place in the comitia curiata, where the thirty lictors representing the thirty Roman curiae witnessed the adoption and passed a lex curiata of consent to the adoption.
