In feudal societies, the fidelity, trust, and service that vassals owed to their lords was known as

Homage is a formal acknowledgment of allegiance or respect that a vassal would give to a lord, often involving a ceremonial act. While it is related to the institution of fealty, it does not encompass the full spectrum of loyalty and service that fealty represents; homage is more about the act of recognition rather than the ongoing obligation of loyalty.

Danegeld was a tax or tribute paid to Viking invaders to prevent them from raiding. This term is entirely unrelated to the personal bonds of loyalty and service between vassals and lords in the feudal system. It reflects a financial transaction rather than a reciprocal relationship of fidelity.

A fief is a piece of land granted by a lord to a vassal in exchange for service and loyalty. While fiefs are integral to the feudal system, they represent the material aspect of the relationship rather than the loyalty and trust inherent in the concept of fealty, which is more about the vassal's personal commitment.
