Fealty is a term that refers to a formal loyalty or allegiance, often in a feudal context. It describes the bond between a vassal and a lord, where the vassal pledges to serve and support the lord in exchange for protection and land. This relationship was crucial in medieval societies, establishing a hierarchy and ensuring mutual obligations. In a broader sense, fealty can apply to any situation where loyalty is pledged, such as in politics or organizations. It emphasizes the importance of trust and commitment, reflecting a promise to uphold certain duties or values in return for support or benefits.
