How to get other empires to agree to "demand vassalization" peacefully?
I'm trying to peacefully expand my empire in Stellaris and I'm thinking of possible ways to do so.
I noticed that you can "demand vassalization" of other empires via the usual diplomatic options. My idea now is to have them join my cause first and then to peacefully integrate them into my empire later.
What are the actual modifiers for this decision? Is there a way of playing that will make other empires actually "want" to be my vassal? What would be helpful techs or traits?

How do you increase Vassalization acceptance?
Opinion, the biggest factor is opinion there are several ways to increase it: mutual rivals, embassy, treaties (border access, non-aggression, guaranteeing, research agreement), making the empire like you is the most important aspect of peaceful vassalization.Stellaris - Vassals \u0026 Tributary Mechanics
