NOBUNAGA'S AMBITION: Sphere of Influence

Foreign affairs allow you to form alliances or marriages that create cooperative stances with the surrounding clans and can lead to aid in battle.
This allows you to gain an advantage in your strategies against your enemies.
Also, by allying yourself with surrounding clans, you can take on the bigger clans with a better chance of winning.
Foreign relations between clans is shown by an arched arrow on the map, so you can tell clan relations at a glance.

Not only can you form foreign relations with nearby tribes, you can also use diplomacy to earn the favor of the Imperial Court.
This could gain you higher titles, which then makes it easier to be successful at foreign negotiations, including brokering peace talks between warring clans.
In addition, colluding with enemy officers allows you to gain enemy information, extract officers from other clans, or even have enemy officers join you during battle.
In addition, you can arrange a truce between warring NPC clans, lure other clans into battling each other, and much more.
