A city-state acquired in this way immediately becomes part of your empire, without any Resistance or damage to buildings and Population, and with all of its units intact! Also, thanks to the high income it can create a strong cultural and diplomatic sphere, which can influence the outcome of the game.

The exact price scales with the progress of the game (and the development of the city-state), starting from around 500 Gold in the Ancient Era and reaching more than 1000 Gold in the Information Era. Religion can also play an important role in Greek diplomacy, because if its religion spreads to an allied city-state, Greece loses Influence with the city-state even slower (or not at all, if the Patronage opener was chosen).ДЄustria's unique ability allows you to spend Gold to acquire allied city-states without having to conquer them by military means, provided the city-state remains your ally for at least five consecutive turns. If all the policies in the Patronage tree are adopted, Greece will be able to maintain a stranglehold on city-state alliances that will be nearly impossible for rival civilizations to break. Use every opportunity throughout the game to do this, and Greece will not only be well on the way to a diplomatic victory but also gain other substantial advantages. It is easy for them to maintain an Allied status with city-states once they achieve it. This ability is arguably more powerful than it looks. Their unique ability makes their Influence with city-states degrade more slowly and recover faster. The Greeks excel at diplomacy and influencing city-states.
