Development of Feudalism

Feudalism in Japan was developed through many events. First, the central government controlling Japan started to weaken due to money loss and loss of authority to large landowners. These estate owners or Daimyo, paid no taxes to the government. They had their own separately  hired army of Samurais. The Samurais were hired to attack other Daimyo.

Smaller land owners pledged their loyalty to Daimyos to protect their land. Often, in return for loyalty, you got military service. These small land owners was called a vassal. These vassals helped Daiymos gain power and that's how feudalism began in Japan.
