👉 Vassalship is a form of political or military alliance in which one party, often referred to as the "vassal," pays tribute and support to another party, called an ally, who is considered a "vassal" by its own ruling monarch. The relationship between these two parties can be either formal (as in the case of a king vowing allegiance to his vassals) or informal (where one party holds sway over the other's territory).
