By Luke dennis
They had to fight and serve their lord according to the right of chivalry. They have to train the nobles son to learn how to fight. Enforcing law in communities. We're required at least 40 days of required military service.
You were part of a brotherhood that was very wealthy and lived above the law. You were a highly trained and well equipped fighting machine.
Disadvantages are that you have to fight and battle all the time and have the risk of death.
Day in the life
The day starts at dawn with mass and prayers. They would do military things and go about the community. Knights would have to do whatever The Lord asked of them.
