Diplomacy is the art of making relations with other civilizations in Civilization VI. Having been overhauled from past games, Diplomacy is a mechanic that evolves as eras pass, starting with periods of near constant warfare in ancient times, to more civil interactions in the mid-to-late game.
Upon first meeting a rival civilization, it may be possible to exchange knowledge of others capitals.
To raise your relationship you could:
- Offer a favorable trade.
- Establish a Trade Route.
- Grant Open Borders.
- Send a delegation or establish an embassy.
- Satisfy one of their agendas.
To lower your relationship you could:
- Declare War.
- Occupy one of their cities.
- Break a promise.
- Go against one of their agendas.
All AI controlled rivals are governed by an Agenda, which affect how they view other civilizations. Each Leader has a set agenda based on their historical traits, which affects their opinions ande playstyles.
Each also has a hidden agenda, which is randomly assigned, to further modify their behavior. Unlike the Leader Agenda, hidden agendas must be uncovered through gossip or espionage.
Players can, for a fee, send delegates to rival civilizations, boosting relations and increasing diplomatic visibility.
Unlike in Civilization V, attitudes towards warmongering change through the eras. In the ancient era, the warmongering penalty is non-existent, and does not become significant until the Renaissance Era. In general, a surprise war will garner more enmity from rivals than a justified war.
A "surprise war" is any declaration of war without any attached cassus belli. Until the mid-game, this is the only form of warfare and will not incur as many diplomatic penalties. In later eras, declaring war without a cassus belli will be frowned upon.
A casus belli can be used to declare justified war, which decreases the diplomatic penalties based on how "just" the war is.
