Bushido

Bushido (^?, "the way (or the moral) of the warrior") is a Japanese term for the samurai way of life, loosely analogous to the concept of chivalry in Europe.

The "way" itself originates from the samurai moral values, most commonly stressing some combination of frugality, loyalty, martial arts mastery, and honor until death. Born from Neo-Confucianism during times of peace in Tokugawa Japan and following Confucian texts, Bushido was also influenced by Shinto and Zen Buddhism, allowing the violent existence of the samurai to be tempered by wisdom and serenity. Bushidō developed between the 16th and 20th centuries, debated by pundits who believed they were building on a legacy dating back to the 10th century, although some scholars have noted that the term bushidō itself is "rarely attested in premodern literature", but it was frequently alluded in Japanese culture and literature.

Under the Tokugawa Shogunate, some aspects of warrior values became formalized into Japanese feudal law.

The word was first used in Japan during the 17th century in Kōyō Gunkan. It came into common usage in Japan and the West after the 1899 publication of Nitobe Inazō's Bushido: The Soul of Japan.
