Diplomacy

Manage relations through Nation Menu → Diplomacy (Java), or the /nation treaty commands. All diplomacy actions require the Manage Diplomacy permission. Two nations can hold one relation at a time.

Relation types

Relation	Meaning	Blocks war?	Breaking it
Alliance	Close partnership.	Yes	Starts a war cooldown (default 24h) before you may attack each other.
Non-Aggression Pact (NAP)	"We won't fight."	Yes	Breaks instantly, no cooldown.
Mutual Defense Pact (MDP)	Defensive alliance — allies can join your defense.	Yes	War cooldown on break.
Mutual Aggression Pact (MAP)	Offensive + defensive — allies can join your attacks and defenses.	Yes	War cooldown on break.
Enemy	A public hostile marker, declared unilaterally.	No	Clear it any time with treaty break — no cooldown.

Marking someone an Enemy doesn't affect war rules at all (it's purely a public "we don't like them" marker) — war is still gated entirely by neutrality, treaties, and the session schedule. See Declaring War.

Making and managing treaties

Command	What it does
/nation treaty propose alliance\|nap\|defense\|aggression <nation>	Offer a treaty.
/nation treaty accept <nation>	Accept an incoming offer.
/nation treaty deny <nation>	Decline an incoming offer.
/nation treaty cancel <nation>	Withdraw your own outgoing offer.
/nation treaty break <nation>	End an active treaty (or clear an enemy marker).
/nation treaty enemy <nation>	Mark another nation as an enemy — no consent needed.

You can also review signed pacts and pending proposals in Nation Menu → Library → Documents, where clicking a document lets you accept, deny, cancel, or break it directly.
