They were the elite troops of medieval Japan.
Samurai was originally called the warrior aristocrats (bushi), but from the twelfth century, the term began to be used as the name for all members of the military-feudal estates of minor nobles.
The ideal samurai was supposed to be a stoic warrior who followed an unwritten code of conduct, to be brave, and, if necessary, to commit ritual suicide.
The samurai lived in Japan in the nineteenth century and their pictures can be admired.
