An unlikely feature but a wish none the less.
When imposing peace on a rival faction, it would be nice if you could force their civilization to become a subject state, as one of the terms of peace.
This would mean that their nation would become a puppet of yours. They would still control their infrastructure, but you can make changes as you see fit.
Positive aspects for the ruling nation:
Mutual-protection pact and right of passage
Transfer and/or direct control of military units (Mercenaries
)
Taxation
Trade bonus
Impose government of choice (Force a communist regime on those lousy democrats)
Colonise their cities with your own people
Negative aspects for the subject state:
Subject states own culture gradually diminishes
Increased risk of culture flipping
Involuntary wars and loss of profit
Increased risk of rioting
You cannot declare war on anyone nor can you join any treaties
Ruling nation can place his military units in your cities
