As far as I know, it's the same as RTW: it triggers when you don't have a certain threshold number of generals, relative to the number of provinces you own. You'll get more Men of the Hour promotions if you conquer territory rapidly (more rapidly than the normal birth/maturation of family members), or if you lose a bunch of male family members to disease, assassination, or combat.Originally Posted by Tuidjy
You might be able to trigger more captain promotions with your Holy Land armies if you kill off family members and generals back home, like sending them solo against big rebel stacks. Of course the trade-off is that you might be sacrificing high-ranked generals with good retinues for newbies, just to gain geographic position.
At least I think that's how it works. It's basically a quota system.
