I'm fairly sure I've made allies into vassals or at the very least Dynastic Marriages into vassals, but I'm wondering, after you make a nation a Tributary, can you later make that country a vassal?
Just trying to plan my take over of Indonesia as Japan. If I can make tributaries -> vassals and then diploannex them at a later date, I'm peachy. If not, I need to figure out another way to make those smaller island nations vassals.
