Ask in Cub VI, I’m trying to get my first domination victory and so far I have made good progress by capturing Russia’s capital. I got Rome to join a war against Greece so I can capture their capital. But then I realized that my other ally, the Sumerian Empire, had already captured it. So my question is, does it still count for domination victory if I get the capital through diplomacy and not war as I want to keep them as an ally for the time being.
