speed x100Alliance diplomacy: confederation, NAP, war
Leaders and officers can propose a confederation or a non-aggression pact (the other side must accept) or declare war (no acceptance needed).
Open the Alliance page, Diplomacy, and enter the other alliance's tag.
Pending proposals can be accepted by the other side or withdrawn. An active treaty can be ended.
Confederation and non-aggression pact: while active, members of the two alliances cannot attack, raid or scout each other (villages and oases). Reinforcing and trading still work.
War is a public statement; it does not change the rules. Members of the same alliance can never attack each other.
