The middle ages were after the germatic kingdom fell apart. They had little towns that were walled because they were frequently attacked. This area was also called the medieval times.
Kings were at the top of the social pyramid. To keep their people loyal they would give land to noblemen. They passed down their power to the oldest son didn't have to earn power. Since they owned so much land they lived a very rich life.
The church officials are very important because of the roman catholic church. Christianity is what united all the kingdoms. The leader of the Catholic church is called a pope.
Serfs & peasants
It took a lot of work to become a knight. They had to go through four stages before being knighted. Most knights belonged to their noble man's town, but if the king was under attack then they were forced to help protect the king.
These were anything of value. At this time it was mostly land, and they were given in exchange for loyalty. Kings would their land to lords, and lords would give the land to farmers.
Although serfs and peasants were both at the bottom of the social pyramid serfs still had better staus but an equally as hard life. Most peasants were farmers or cattered to their lords. Serfs had the same jobs them but they could pay thier way out, but they were protcted by the king unlike the peasents.
