What does vassal mean?
A vassal is a person, kingdom, or other political unit that owes allegiance to a more powerful authority. In its historical sense, the word refers to a feudal tenant who held land from a superior lord and owed that lord service or obedience. In later political usage, a vassal state acknowledged the supremacy of another state while retaining some internal authority. Today, “vassal” can also be used figuratively to describe someone who is subordinate, dependent, or excessively deferential to another person or organization. The term is usually formal and carries a historical or political resonance, often suggesting a relationship marked by unequal power. Because it evokes feudal hierarchy and political dependence, it may be used critically when describing modern alliances or institutions in which one party appears to have little autonomy.
A person who holds land or serves a superior lord under a feudal arrangement; a subordinate state or political unit; or, figuratively, a dependent or subservient person.
"The emperor installed a loyal vassal as ruler of the conquered territory."
The historical sense is common in medieval and political contexts. Modern figurative uses often imply a lack of autonomy or excessive deference.
Of or relating to a vassal; subordinate, dependent, or characteristic of a person or state that owes allegiance to a superior authority.
"The vassal kingdom was permitted to retain its own court and laws."
This use is mainly formal, historical, or political, and can occur in phrases such as “vassal state.”
The standard plural of the noun is “vassals,” used for multiple feudal tenants, subordinate states, or figuratively dependent individuals.
"Several vassals pledged allegiance to the duke during the ceremony."
From feudal tenant to modern political metaphor, a vassal has always been defined by a relationship of dependence—though the name says more about the superior's power than the subordinate's loyalty.

Etymology of vassal
The word entered Middle English from Old French vassal, meaning a feudal tenant or subordinate. Old French borrowed it from Vulgar Latin vassallus, a term associated with a Germanic source for a tenant or dependent of a lord.
