they can keep trading ports
R4WLYX: A new military province has been established in the west; soldiers and cavalry have been trained there. The barbarians are being conquered. The Lorca League has accepted your alliance.
The Kasuta Confederacy is willing to help you fight the southern tribe, so long as they can keep trading ports.
7shotsolo: The tribes decline the offer. You have conquered the central tribe, and the remaining population are begging for mercy. The southern tribe keeps fighting.
The diplomat has to be a part of the trading province and has walked through the trade route. They will use the same trade route to send this message
Also i would like to send a diplomat guarded by 20 guards for an offer to the Lorca League. The offer reads "I, ruler of The Floor Nation, is giving you an oppurtunity of peace, the offer is you will be my ally and will help my nation with resources, knowledge, and military support, I will also do the same. I would like to offer you my nation's bronze scale armour and fertelizer. Once you have accepted I shall meet you personally in your nation to talk about this allyship"
x285 y170 I made a mistake
If most of the civillians doesn't want to join the army it's fine. If they do not like the idea of a military province then they have to get used to living with highly trained soilder in their area
