Commodore Perry's "black ships" forced Japan to open to the West. The subsequent military humiliation of the samurai-led government by technologically superior foreign powers shattered their prestige, triggering the Meiji Restoration and the rapid abolition of the entire samurai class.

Navy veteran Kai Ryssdal posits that the military doesn't create character from scratch. Instead, it serves as a crucible for individuals who already possess a sense of duty. The service refines, sharpens, and distills these pre-existing qualities, embedding them as a lifelong code of conduct.

Early samurai were viewed as low-class outsiders by the sophisticated imperial court. To combat this snobbery and establish their own legitimacy, they developed demanding ideals, moral codes, and myths, an urgent social necessity for an upwardly mobile class.

The powerful Minamoto and Taira samurai clans originated as a solution to an overabundance of imperial princes. Emperors removed these sons from the succession by giving them surnames and sending them to the provinces, where they formed powerful warrior clans.

During the peaceful Tokugawa Shogunate era, the samurai class functioned primarily as civil administrators. Despite the lack of warfare, they were legally obligated to maintain military readiness and wear armor, effectively role-playing as the warriors their ancestors had been.

A British Museum exhibit shows the clear lineage from samurai armor to modern pop culture icons. George Lucas specifically instructed his costume designer to create "some kind of big helmet like a Japanese warrior" for Darth Vader, cementing the aesthetic's global influence.

The word 'samurai' did not originally mean warrior. Its literal meaning is 'a vassal, a subordinate, a person who is in service to a great lord.' This reflects the early medieval period when warriors were considered low-class outsiders by the ruling court aristocracy.

Taira no Masakado, hailed as the first samurai, was not a commoner but a member of the imperial family. His turn to provincial warfare was driven by a bitter sense of being snubbed by the central court, culminating in him declaring himself a new emperor in the east.

Unlike in medieval Europe, the ruling class in Japan's imperial court in Kyoto valued arts like poetry over military prowess. Warriors were seen as uncouth and vulgar. This cultural contempt for violence led the aristocracy to neglect military power, enabling the rise of the samurai.
