Overview | Terrain | Cities | Economy | Units | Combat | Diplomacy | Government | Technology | Wonders | Buildings | [ edit navbar] A city is created when settlers are given the build city command, removing the unit from play to provide the city with its first citizen. A city may grow to include several citizens, some working within the city while others are dispatched as new settlers. Famine and war kill citizens and reduce population; with the loss of its last citizen a city disappears. On the Freeciv map each city is labelled with its population, also called its size.
