Nativity is the first city that a participant starts the game in. This is updated if the city becomes inaccessible. In this case, the gamemaster will either choose a city to replace the previous one based on the participant's activity or wait until the participant plays again. Nativity will also change if the participant fully takes part in a newly formed government of a new country of a city that is new to the game. Nativity does not change if this is done with an existing city or if the participant remains primarily active in a previous government. The purpose of nativity is to help governments and sports teams better classify simulated nationality in a more realistic manner. The rule was added in FEB25, and nativity was retroactively added to all non-NPC participants that have played in the Eternal City Era.
