The word samurai means “servant or a person who serves." Samurai were members of a powerful military caste in Japan. But this warrior had no ranks. Samurai follow a strict code of conduct known as "bushido," which means "the way of the warrior." It is also considered that the bushido had a religious status for them. They also fought for the honor and dignity of their country and people. Samurai use bows and arrows as their weapons when the enemies are far. But when the enemies are near, they use a sword. Samurai take care of their sword as if it is their honor or life. They carried two swords in the battle: a katana and a shorter blade. They also wore armor to protect themselves from the enemies, but their armor was light in weight and not as strong as a knight's.
