"Diplomatic Capital is the currency of diplomacy. It represents a mixture of your leader's power, experience, and prestige on the global stage. You earn Diplomatic Capital locally from wonders and special buildings, and you earn it internationally when you allow other leaders initiate agreements. Likewise, you spend Diplomatic Capital when you initiate and maintain agreements with other leaders. You can also spend it to level up or change your leader's Personality Traits, which will improve its effects."

Diplomatic Capital, like the Faith resource in the Gods & Kings expansion for Civilization V, is used to gain special perks in the form of Personality Traits and Diplomatic Agreements. Unlike Religious Beliefs in Gods & Kings, however, two or more leaders can have the same traits if they want to, so this is not a "first come, first serve" style of gameplay. Diplomatic Capital can also be used to buy units and buildings, in the same way Energy can be used. However, the resource cost to purchase is doubled when using than when using .
