The Code of the Samurai
Bushido is a code of conduct that emerged in Japan from the Samurai, or Japanese warriors, who spread their ideals throughout society. They drew inspiration from Confucianism, which is a relatively conservative philosophy and system of beliefs that places a great deal of importance on loyalty and duty.
There were seven official virtues of Bushido: righteousness, courage, benevolence, respect, honesty, honour, and loyalty. Piety, wisdom, and care for the elderly were unofficial virtues. By following the Bushido code, a samurai would maintain both honour and political power in Japanese society.
Under the Tokugawa shogunate, some aspects of warrior values became formalized into Japanese feudal law. The word bushidō was first used in Japan during the 17th century in Kōyō Gunkan, but did not come into common usage until after the 1899 publication of Nitobe Inazō's Bushido: The Soul of Japan.
The final phase of the development of bushido was the Tokugawa era, from 1600 to 1868.
Bushido applies to a true warrior which plenty of people still live today, for example the US Marines follow Bushido . The Way of the Warrior can still be applied to life today. You can still live of life following Seven Virtues of Bushido.
