What where the basic levels from most powerful to least under European feudalism?

In European feudalism, the basic hierarchy from most powerful to least was composed of the king at the top, followed by powerful nobles or lords who held large estates. Below them were vassals or lesser nobles who served the lords in exchange for land. Peasants and serfs occupied the lowest level, working the land and providing labor, often bound to the land they farmed. This structure created a system of mutual obligations and loyalty among the different classes.
