Samurai (侍) is the term for the military nobility of pre-industrial Japan. According to translator William Scott Wilson: "In Chinese, the character 侍 was originally a verb meaning to wait upon or accompany a person in the upper ranks of society, and this is also true of the original term in Japanese, saburau. In both countries the terms were nominalized to mean "those who serve in close attendance to the nobility," the pronunciation in Japanese changing to saburai. According to Wilson, an early reference to the word "samurai" appears in the Kokin Wakashū (905–914), the first imperial anthology of poems, completed in the first part of the 10th century.
By the end of the 12th century, samurai became almost entirely synonymous with bushi (武士), and the word was closely associated with the middle and upper echelons of the warrior class. The samurai followed a set of rules that came to be known as Bushidō. While they numbered less than 10% of Japan's population samurai teachings can still be found today in both everyday life and in martial arts such as Kendō, meaning the way of the sword.
History
Following the Battle of Hakusukinoe against Tang China and Silla in 663 AD that led to a Japanese retreat from Korean affairs, Japan underwent widespread reform. One of the most important was that of the Taika Reform, issued by Prince Naka no Ōe (Emperor Tenji) in 646 AD. This edict allowed the Japanese aristocracy to adopt the Tang Dynasty political structure, bureaucracy, culture, religion, and philosophy. As part of the Taihō Code, of 702 AD, and the later Yōrō Code, the population was required to report regularly for census, which was used as a precursor for national conscription. With an understanding of how the population was distributed, Emperor Mommu introduced the law whereby 1 in 3–4 adult males was drafted into the national military. These soldiers were required to supply their own weapons, and in return were exempted from duties and taxes. This was one of the first attempts by the Imperial government to form an organized army modeled after the Chinese system. It was called gundan-sei (軍団制) by later historians and is believed to have been short-lived.
The Taihō Code classified most of the imperial bureaucrats into 12 ranks, each divided into two sub-ranks, 1st rank being the highest adviser to the emperor. Those of 6th rank and below were referred to as "samurai" and dealt with day-to-day affairs. Although these "samurai" were civilian public servants, the name is believed to have derived from this term. Military men, however, would not be referred to as "samurai" for many more centuries.
In the early Heian period, the late 8th and early 9th centuries, Emperor Kammu sought to consolidate and expand his rule in northern Honshū, but the armies he sent to conquer the rebellious Emishi people lacked motivation and discipline, and failed in their task. Emperor Kammu introduced the title of Seiitaishogun (征夷大将軍) or shogun, and began to rely on the powerful regional clans to conquer the Emishi. Skilled in mounted combat and archery (kyūdō), these clan warriors became the emperor's preferred tool for putting down rebellions. Although this is the first time 'shogun' title is used, it was a temporal title and had not been accompanied with political power until 13th century, and at this time (7th to 9th century) the imperial court officials considered them to be merely military section under control of imperial court.Ultimately, Emperor Kammu disbanded his army. From this time, the emperor's power gradually declined. While the emperor was still the ruler, powerful clans around Kyoto (京都) assumed positions as ministers, and their relatives bought positions as magistrates. To amass wealth and repay their debts, magistrates often imposed heavy taxes, resulting in many farmers becoming landless. Through protective agreements and political marriages, they accumulated political power, eventually surpassing the traditional aristocracy. Some clans were originally formed by farmers who had taken up arms to protect themselves from the imperial magistrates sent to govern their lands and collect taxes. These clans formed alliances to protect themselves against more powerful clans, and by the mid-Heian period they had adopted characteristic Japanese armour and weapons, and laid the foundations of Bushido, their ethical code.
