The Heian period (平安時代, Heian jidai) is the last division of classical Japanese history, running from 794 to 1185. It followed the Nara period, beginning when the 50th emperor, Emperor Kammu, moved the capital of Japan to Heian-kyō (modern Kyoto). Heian (平安) means 'peace' in Japanese. It is a period in Japanese history when the Chinese influences were in decline and the national culture matured. The Heian period is also considered the peak of the Japanese imperial court, noted for its art, especially poetry and literature. Two syllabaries unique to Japan, katakana and hiragana, emerged during this time. This gave rise to Japan's famous vernacular literature, with many of its texts written by court ladies who were not as educated in Chinese as their male counterparts.
Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic family who had intermarried with the imperial family; most Emperors of the Heian era had mothers from the Fujiwara family. The economy mostly existed through barter and trade due to the lack of a national currency, while the shōen system encouraged the growth of aristocratic estates that began gradually asserting their independence from Imperial control. Despite a lack of serious warfare or domestic strife during the Heian era, crime and banditry were widespread as the Emperors failed to police the country effectively.
History
The Heian period was preceded by the Nara period and began in 794 CE after the movement of the capital of Japan to Heian-kyō (modern Kyoto), by the 50th emperor, Emperor Kanmu. Kanmu first tried to move the capital to Nagaoka-kyō (modern Kyoto), but a series of disasters befell the city, prompting the emperor to relocate the capital a second time, to Heian. A rebellion occurred in China toward the end of the 9th century, making the political situation unstable. The Japanese missions to Tang China were suspended and the influx of Chinese exports halted, a fact which facilitated the independent growth of Japanese culture called kokufū bunka (国風文化). Eventually, the eastern province of Hitachi (modern Ibaraki), and almost simultaneously, Fujiwara no Sumitomo rebelled in the west; samurai played a crucial role in suppressing both disturbances on behalf of the Emperor. In the rebellious north, the latter half of the 11th century saw the Former Nine Years War and the Latter Three Years' War between the central government and the Abe and Kiyohara clan respectively. Still, a true military takeover of the Japanese government was centuries away, when much of the strength of the government would lie within the private armies of the shogunate.
By the 12th century, court authority weakened as the decentralized land allocation system managed by aristocratic vassals, preferring life at court over regional administration, made the system increasingly ineffective. The entry of the warrior class into court influence was a result of the 1156 Hōgen Rebellion. At this time Taira no Kiyomori revived the Fujiwara practices by placing his grandson on the throne to rule Japan by regency. Their clan, the Taira, would not be overthrown until after the Genpei War, which marked the start of the Kamakura shogunate. The Kamakura period began in 1185 when the family of Minamoto no Yoritomo seized power from the emperors and established the shogunate in their ancestral home, Kamakura.
Fujiwara regency
When Emperor Kammu moved the capital to Heian-kyō (Kyoto), which remained the imperial capital for the next 1,000 years, he did so not only to strengthen imperial authority but also to improve his seat of government geopolitically. Nara was abandoned after only 70 years in part due to the ascendancy of the Buddhist monk Dōkyō and the encroaching secular power of the Buddhist institutions there. Kyoto had good river access to the sea and could be reached by land routes from the eastern provinces. The early Heian period (784–967) continued Nara culture; the Heian capital was patterned on the Chinese Tang capital at Chang'an, as was Nara, but on a larger scale than Nara. Kammu endeavored to improve the Tang-style administrative system which was in use. Known as the Ritsuryō Code, this system attempted to recreate the Tang legal system in Japan, despite the "tremendous differences in the levels of development between the two countries". Despite the decline of the Taika–Taihō reforms, the imperial government was vigorous during the early Heian period. Kammu's avoidance of drastic reform decreased the intensity of political struggles, and he became recognized as one of Japan's most forceful emperors.
Although Kammu had abandoned universal conscription in 792, he still waged major military offensives to subjugate the Emishi, possible descendants of the displaced Jōmon, living in northern and eastern Japan. After making temporary gains in 794, in 797, Kammu appointed a new commander, Sakanoue no Tamuramaro, under the title Seii Taishōgun (征夷大将軍, "Barbarian-subduing generalissimo"). By 801, the shōgun had defeated the Emishi and had extended the imperial domains to the eastern end of Honshū. Imperial control over the provinces was tenuous at best, however. In the 9th and 10th centuries, much authority was lost to the great families, who disregarded the Chinese-style land and tax systems imposed by the government in Kyoto. Stability came to Japan, but, even though succession was ensured for the imperial family through heredity, power again concentrated in the hands of one noble family, the Fujiwara.
Following Kammu's death in 806 and a succession struggle among his sons, two new offices were established in an effort to adjust the Taika–Taihō administrative structure. Through the new Emperor's Private Office, the emperor could issue administrative edicts more directly and with more self-assurance than before. The new Metropolitan Police Board replaced the largely ceremonial imperial guard units. While these two offices strengthened the emperor's position temporarily, soon they and other Chinese-style structures were bypassed in the developing state. In 838 the end of the imperial-sanctioned missions to Tang China, which had begun in 630, marked the effective end of Chinese influence. Tang China was in a state of decline, and Chinese Buddhists were severely persecuted, undermining Japanese respect for Chinese institutions. Japan began to turn inward.
As the Soga clan had taken control of the throne in the sixth century, the Fujiwara by the 9th century had intermarried with the imperial family, and one of their members was the first head of the Emperor's Private Office. Another Fujiwara became regent, Sesshō for his grandson, then a minor emperor and yet another was appointed Kampaku. Toward the end of the 9th century, several emperors tried but failed to check the Fujiwara. For a time, however, during the reign of Emperor Daigo (897–930), the Fujiwara regency was suspended as he ruled directly.
Nevertheless, the Fujiwara were not demoted by Daigo but actually became stronger during his reign. Central control of Japan had continued to decline, and the Fujiwara, along with other great families and religious foundations, acquired ever larger shōen and greater wealth during the early 10th century. By the early Heian period, the shōen had obtained legal status, and the large religious establishments sought clear titles in perpetuity, waiver of taxes, and immunity from government inspection of the shōen they held. Those people who worked the land found it advantageous to transfer title to shōen holders in return for a share of the harvest. People and lands were increasingly beyond central control and taxation, a de facto return to conditions before the Taika Reform.
Within decades of Daigo's death, the Fujiwara had absolute control over the court. By the year 1000, Fujiwara no Michinaga was able to enthrone and dethrone emperors at will. Little authority was left for traditional institutions, and government affairs were handled through the Fujiwara clan's private administration. The Fujiwara had become what historian George B. Sansom has called "hereditary dictators".
Despite their usurpation of imperial authority, the Fujiwara presided over a period of cultural and artistic flowering at the imperial court and among the aristocracy. There was great interest in graceful poetry and vernacular literature. Two types of phonetic Japanese script: katakana, a simplified script that was developed by using parts of Chinese characters, was abbreviated to hiragana, a cursive syllabary with a distinct writing method that was uniquely Japanese. Hiragana gave written expression to the spoken word and, with it, to the rise in Japan's famous vernacular literature, much of it written by court women who had not been trained in Chinese as had their male counterparts. Three late-10th and early-11th century women presented their views of life and romance at the Heian court in Kagerō Nikki by "the mother of Fujiwara Michitsuna", The Pillow Book by Sei Shōnagon and The Tale of Genji by Murasaki Shikibu. Indigenous art also flourished under the Fujiwara after centuries of imitating Chinese forms. Vividly colored yamato-e, Japanese style paintings of court life and stories about temples and shrines became common in the mid-to-late Heian period, setting patterns for Japanese art to this day.
As culture flourished, so did decentralization. Whereas the first phase of shōen development in the early Heian period had seen the opening of new lands and the granting of the use of lands to aristocrats and religious institutions, the second phase saw the growth of patrimonial "house governments", as in the old clan system. In fact, the form of the old clan system had remained largely intact within the great old centralized government. New institutions were now needed in the face of social, economic, and political changes. The Taihō Code lapsed, its institutions relegated to ceremonial functions. Family administrations now became public institutions. As the most powerful family, the Fujiwara governed Japan and determined the general affairs of state, such as succession to the throne. Family and state affairs were thoroughly intermixed, a pattern followed among other families, monasteries, and even the imperial family. Land management became the primary occupation of the aristocracy, not so much because direct control by the imperial family or central government had declined but more from strong family solidarity and a lack of a sense of Japan as a single nation.
Rise of the military class
Under the early courts, when military conscription had been centrally controlled, military affairs had been taken out of the hands of the provincial aristocracy. But as the system broke down after 792, local power holders again became the primary source of military strength. The re-establishment of an efficient military system was made gradually through a process of trial-and-error. At that time the imperial court did not possess an army but rather relied on an organization of professional warriors composed mainly of oryoshi, which were appointed to an individual province and tsuibushi, which were appointed over imperial circuits or for specific tasks. This gave rise to the Japanese military class. Nonetheless, final authority rested with the imperial court.
Shōen holders had access to manpower and, as they obtained improved military technology (such as new training methods, more powerful bows, armor, horses, and superior swords) and faced worsening local conditions in the 9th century, military service became part of shōen life. Not only the shōen but also civil and religious institutions formed private guard units to protect themselves. Gradually, the provincial upper class was transformed into a new military elite of samurai.
Bushi interests were diverse, cutting across old power structures to form new associations in the 10th century. Mutual interests, family connections, and kinship were consolidated in military groups that became part of family administration. In time, large regional military families formed around members of the court aristocracy who had become prominent provincial figures. These military families gained prestige from connections to the imperial court and court-granted military titles and access to manpower. The Fujiwara family, Taira clan, and Minamoto clan were among the most prominent families supported by the new military class.
A decline in food production, the growth of the population, and competition for resources among the great families all led to the gradual decline of Fujiwara power and gave rise to military disturbances in the mid-10th and 11th centuries. Members of the Fujiwara, Taira, and Minamoto families—all of whom had descended from the imperial family—attacked one another, claimed control over vast tracts of conquered land, set up rival regimes, and generally upset the peace.
