The word 'vassal' is used to describe a person who is loyal to and serves a more powerful person or country. This relationship is usually based on a system of agreements or promises, where the vassal offers their loyalty and services in exchange for protection or support from their superior. In medieval Europe, some nobles were vassals of higher-ranking lords or kings. Nowadays, the term is more often used to describe countries that have a dependent relationship with another country or organization, such as a colony or a protectorate.
