Governors an their replacements

[WinsingtonIII]

Well you do already have the feature of appointing a new local governor from Type IV governments (semi-autonomous city-states/tribes, etc.) by which you just recruit a new local general/governor. I'm not sure if EB2 will have this same feature or if it will be modified somewhat.

As for the historical question, I'd imagine it really depended on the type of settlement (military-governorship vs semi-autonomous ally vs homeland province vs colony vs whatever other types of settlements you can think of) and the cultural practices of the ruling empire. I'm no expert on Romans so I cannot speak for certain on their practices, but I do know that during Alexander the Great's campaign (which is only slightly before our timeline), he would sometimes put Macedonians in charge of a newly conquered region (which is like sending a new governor from home in game) and sometimes he would put locals in charge (which is sort of like recruiting a local general in EB). He, and the Seleucids after him, largely kept the Persian satrapal system in place, by which most regions would be governed by appointed satraps who exhibited some degree of autonomy. Whether or not those satraps were of Hellenic or local origin depended on the region; some areas expected local rulers more than others and would be less likely to tolerate a Hellenic satrap.

Then again, this practice is not representative of all empires of the time, as everyone tends to do things slightly differently. But in general, I think you would find a variety of different practices depending on how far away the the settlement is from the homeland, how prone it is to revolt, how much local autonomy it enjoys/expects, and how recently it was conquered.
