The feudal system would follow from the king down to the serfs.
What is confusing is the lords vs. knights. Lords will rule over knights and knights will rule over serfs.

King
Lord — Lord — Lord
Knight — Knight — Knight — Knight — Knight — Knight
And serfs
Hope this helps, have a great day!
Defenders of the faith have been raised up in every era of the Church to proclaim fidelity to the truth by their words and deeds. Some have fought heresy and overcome confusion like Athanasius against the Arians and Ignatius Loyola in response to the Protestant reformers. Others have shed their blood for the faith, like the early Christian martyrs of Rome, or Thomas More, John Fisher and Edmund Campion in Reformation England.
