In the olden days, when kings ruled countries in England, they didn't just have their own land to keep and protect. They also had a lot of other people who helped them to rule and take care of the land. These people were called lords or barons.
Now, imagine a lord had a lot of land that he couldn't take care of all by himself. He would give some of that land to other people to take care of it for him. These people were called vassals. In return, the vassals pledged to be loyal to the lord and to fight for him if needed.
The arrangement between the lord and vassal was called the feudal system. It was like an agreement where the lord would provide protection, while the vassal would provide his service and loyalty.
A barony was a big area of land that a lord owned. The lord would appoint a powerful vassal to manage the barony and take care of the land on his behalf. The vassal was called a baron.
A baron had to make sure that the land was safe and that people who lived on it were protected. He would collect taxes from people who lived on the land and provide those taxes to the lord to help him maintain his power.
Over time, as the number of barons grew in England, it became difficult for the king to manage them all. Therefore, the king started to give some of the barons more important roles in the government.
However, even when they became powerful, the barons still had to remain loyal to the king and provide him with their support when he needed it. If they didn’t provide the support, their land could be taken away by the king. This system of managing land and power through loyalty and protection was called the English feudal barony.
