How Ownership Changes
Free at the start, capture-only after.

Set Once, Then Earned
Ownership is assigned once, for free, at the start of a match — claiming a country hands you every province it owns immediately. After that, the only thing that ever changes an owner is the capture mechanic: infantry on the marker plus a timer, covered in full in Province Capture. Cities inside a captured province change hands with it but stay frozen until annexed — see Conquest.
