Promotion to general

[Upxl]

I'm currently playing my second RTW campaign with Parthians and have 8 family members at the moment. I was wondering how many battles does a captain have to win to be promoted to general and on what does it depend on?

Thanks in advance

It depends on the fact Generals/provinces.

You could go for ages without getting that promotion.
I red in frogbeast’s guide that “when a captain gets promoted to two stars you get the option of adopting”
I found this to be incorrect.
It also happens after an “Heroic battle”
But still this depends on how many family members/province

I’m playing the Roman campaign now and have a low % off governors.
Even after a “victory is almost certain” battle I still get asked to adopt the captain in my family.
