City-States, previously introduced in Civilization V, are singular cities that act independent of the player and rival Leaders in Civilization VI. They have their own political relationships, can engage in War, and provide players a means of diplomacy outside of dealing with the major Civilizations. In Civilization VI, City-States are much more streamlined over their Civilization V counterparts, and feature updated Quests that become visible after a player sends an Envoy there. Completing a City-State’s quests earn additional Envoys there, which help you enact more influence and earn greater rewards as you continue to strengthen your relationship that particular City-State.
Civilizations still gain Influence with City-States, but a civilization's relationship with a City-State is now determined by the number of Envoys that the civilization has allocated to that City-State. Envoys are earned over time with Influence (which in turn can be increased through certain government and social policy types), and can also be earned through City-State quests or other special effects. City-States grant bonus yields (based on type) to civilizations that have sent Envoys; more Envoys earn more bonuses from the City-State. A civilization that has sent at least 3 Envoys can become "Suzerain" for that City-State, and earn a special bonus unique to that City-State. If more than one civilization has sent 3 Envoys, then whichever has the most becomes Suzerain. There can be only one Suzerain for a given City-State at a time. City-States follow their Suzerain into war and peace with other players. The Suzerain receives all Resources the city-state owns, and may also pay Gold to temporarily take control of the city-state's Units. Each city-state has a unique icon and Suzerain bonus.

City State Info
- There's a brand new City-State Diplomacy interaction, and the Influence bar has been removed, instead you send Envoys to City-States.
- You gain tiered bonuses depending on the amount of envoys you assign to a City-State and their City-State Type.
- Completing a City-State Quest adds 1 additional Envoy to that City-State. This Envoy is subject to the same mechanics as manually added Envoys. Also the City-State City immediately expands territory by 1 tile (possibly other boosts as well?).
- Each City-State can have at most 1 quest active at a time. New City-State quests are awarded upon first encounter with the City-State and every time an era is advanced there after. Era dependant Quests are replaced by new quests upon era advancement. City-State Quests are failed if either the City-State declares war on the player or if the goal is no longer achievable.
- City-State Quests with the goal of boosting a specific Civic or Technology do not care how the Player achieves the boost. Completing the Civic or Technology before achieving any boost will result in Quest failure as the quest goal is no longer achievable.
- City-State military forces will automatically hunt down and destroy nearby Barbarian encampments. Barbarian activity might overwhelm the City-State and prevent it from amassing a military and from developing its territory.
- City-States are subject to Amenity mechanics. Large population City-State Cities might have enough Amenity deficit to cause rebel units to spawn.
- Each City-State will only ever build 1 district in their City. The type of the district built is appropriate for the type of the city state.
List Of City-States
Each of the City-States will have a unique bonus, which will be given once a player has influenced the city-state enough. To gain influence, you can send Envoys to the city-state, to which the city-state will then provide you with different bonuses depending on your influence over them. You can also rent a city-state's military for a period of time, if you are its Suzerain.
