City-States are small independent political entities introduced in Civilization V, which could be linked in the real world to the small nations of little significance that don't have any ambitions for world domination. In essence, they are single-city civilizations that do not compete against anyone for the victory. Although they have the same capacity for producing units and buildings as normal civilizations, as well as technological and even cultural progress, they cannot build Settler units and thus are (almost) never interested in expansion. They do start with a Settler, who founds the city state on the same tile it spawned at the beginning of the game. Unlike the major civilizations, City-States don't have a military unit right at the beginning of the game.
