The Conqueror Order has been recognized by all the nobles for over a century.
The reason is that while the King is the highest ruler, he does not possess absolute power.
Every Black Iron King faced multiple constraints.
The Black Iron King's authority is under the Order and also under the religious authority.
If a king wants to execute a noble, he must go through procedures such as a royal trial, legal judgment, and accusation of crimes; he cannot execute a noble at will.
The King is more a noble standing at the pinnacle of the pyramid than a king.
When the Black Iron King calls upon all nobles' arms in the name of a conqueror, he can form a formidable force to rival the Church Court.
This is a traditional political maneuver.
The King mediates the conflicts of the great nobles internally and balances the pressure from the Church Court externally.
