The research of Treaties will facilitate a good start in forging relations with other empires, and help to develop a successful foreign policy.
If your vizier keeps whispering in your ear that diplomacy is not the right way to create an empire, that treaties have no practical value, and that respect can only be gained on the battlefield, then perhaps you should look for another vizier. For a wise ruler acts strategically and with foresight: instead of destroying a city and wiping out its population, he pardons them and secures their support and loyalty, preferably in contractual form. If necessary, an agreement of this kind can be supplemented by a marriage contract between the two ruling families.
