what condition triggers new general / man of hour

[Indy1958]

Gents:

Good afternoon from Canada!!! I hope this finds you and yours well. As for me, Icould complain...yadda, yadda, yadda.

Last night, I was playing as the Byzantine Empire, and I found a Rebel army breathing down my neck. I waited a couple of turns to get some more men and when I was ready, I threw out the Rebel trash. This earned my governor a "Man of the Hour" document, plus an invite to be adopted into my Royal Family.

Needless to say, he's now a member of my Royal Family.

Live long and prosper, take care and thank you kindly!!!

Sincerely yours always,

Indy.

I think the ratio is around 1.5 (provinces:family members) and you don't need a heroic victory at all
