Heian period in the context of "Tale of Genji"

Heian-kyō (平安京; lit. "peaceful/tranquil capital") was one of several former names for the city now known as Kyoto. It was the de jure capital of Japan for over one thousand years, from 794 to 1868 with an interruption in 1180.

Emperor Kanmu established it as the capital in 794, moving the Imperial Court there from nearby Nagaoka-kyō at the recommendation of his advisor Wake no Kiyomaro and marking the beginning of the Heian period of Japanese history. According to modern scholarship, the city is thought to have been modelled after the urban planning for the Tang dynasty Chinese capital of Chang'an (modern-day Xi'an). It remained the chief political center until 1185, when the samurai Minamoto clan defeated the Taira clan in the Genpei War, moving administration of national affairs to Kamakura and establishing the Kamakura shogunate.

Shogun (将軍, shōgun; English: /ˈʃoʊ.ɡʌn/ SHOH-gun, Japanese: [ɕoː.ɡɯɴ, -ŋɯɴ] ), officially seii taishōgun (征夷大将軍; Japanese: [seꜜi.i | tai.ɕo(ꜜ)ː.ɡɯɴ, seꜜː-, -ŋɯɴ] lit. 'Commander-in-Chief of the Expeditionary Force Against the Barbarians'), was the title of the military rulers of Japan during most of the period spanning from 1185 to 1868. Nominally appointed by the Emperor, shoguns were usually the de facto rulers of the country, except during parts of the Kamakura period and Sengoku period when the shoguns themselves were figureheads, with real power in the hands of the shikken (執権) of the Hōjō clan and kanrei (管領) of the Hosokawa clan. In addition, Taira no Kiyomori and Toyotomi Hideyoshi were leaders of the warrior class who did not hold the position of shogun, the highest office of the warrior class, yet gained the positions of daijō-daijin (太政大臣, Chancellor of the Realm) and kampaku (関白, Imperial Regent), the highest offices of the aristocratic class. As such, they ran their governments as its de facto rulers.

The office of shogun was in practice hereditary, although over the course of the history of Japan several different clans held the position. The title was originally held by military commanders during the Heian period in the eighth and ninth centuries. When Minamoto no Yoritomo gained political ascendency over Japan in 1185, the title was revived to regularize his position, making him the first shogun in the usually understood sense.

Provinces of Japan (令制国, Ryōseikoku) were first-level administrative divisions of Japan from the 600s to 1868.

Provinces were established in Japan in the late 7th century under the Ritsuryō law system that formed the first central government. Each province was divided into districts (郡, gun) and grouped into one of the geographic regions or circuits known as the Gokishichidō (Five Home Provinces and Seven Circuits). Provincial borders often changed until the end of the Nara period (710 to 794), but remained unchanged from the Heian period (794 to 1185) until the Edo period (1603 to 1868). The provinces coexisted with the han (domain) system, the personal estates of feudal lords and warriors, and became secondary to the domains in the late Muromachi period (1336 to 1573).

The first human inhabitants of the Japanese archipelago have been traced to the Paleolithic, around 38–39,000 years ago. The Jōmon period, named after its cord-marked pottery, was followed by the Yayoi period in the first millennium BC when new inventions were introduced from Asia. During this period, the first known written reference to Japan was recorded in the Chinese Book of Han in the first century AD.

Around the 3rd century BC, the Yayoi people from the continent immigrated to the Japanese archipelago and introduced iron technology and agricultural civilization. Because they had an agricultural civilization, the population of the Yayoi began to grow rapidly and ultimately overwhelmed the Jōmon people, natives of the Japanese archipelago who were hunter-gatherers.Between the 4th and 9th centuries, Japan's many kingdoms and tribes were gradually unified under a centralized government, nominally controlled by the Emperor of Japan. The imperial dynasty established at this time continues to this day, albeit in an almost entirely ceremonial role. In 794, a new imperial capital was established at Heian-kyō (modern Kyoto), marking the beginning of the Heian period, which lasted until 1185. The Heian period is considered a golden age of classical Japanese culture. Japanese religious life from this time and onwards was a mix of native Shinto practices and Buddhism.

Emperor Kanmu (桓武天皇, Kammu-tennō; 735 – 9 April 806), or Kammu, was the 50th emperor of Japan, according to the traditional order of succession. Kammu reigned from 781 to 806, and it was during his reign that the scope of the emperor's powers reached its peak. His reign saw the transition from the Nara period to the Heian period.

Minamoto (源; Japanese pronunciation: [mʲi.na.mo.to]) was a noble surname bestowed by the Emperors of Japan upon members of the imperial family who were excluded from the line of succession and demoted into the ranks of the nobility since 814. Several noble lines were bestowed the surname, the most notable of which was the Seiwa Genji, whose descendants established the Kamakura and Ashikaga shogunates following the Heian era. The Minamoto was one of the four great clans that dominated Japanese politics during the Heian period in Japanese history—the other three were the Fujiwara, the Taira, and the Tachibana.

In the late Heian period, Minamoto rivalry with the Taira culminated in the Genpei War (1180–1185 AD). The Minamoto emerged victorious and established Japan's first shogunate in Kamakura under Minamoto no Yoritomo, who appointed himself as shōgun in 1192, ushering in the Kamakura period (1192–1333 AD) of Japanese history. The name "Genpei" comes from alternate readings of the kanji "Minamoto" (源 Gen) and "Taira" (平 Hei).

The Taira (平; Japanese pronunciation: [taꜜi.ɾa]) was one of the four most important clans that dominated Japanese politics during the Heian period of Japanese history – the others being the Minamoto, the Fujiwara, and the Tachibana. The clan is divided into four major groups, named after the emperors they descended from: Kanmu Heishi, Ninmyō Heishi, Montoku Heishi, and Kōkō Heishi, the most influential of which was the Kanmu Heishi line.

In the twilight of the Heian period, the Taira controlled the boy emperor Antoku (himself the grandson of the powerful Kugyō Taira no Kiyomori) and had effectively dominated the Imperial capital of Heian. However, they were opposed by their rivals the Minamoto clan (the Genji), which culminated in the Genpei War (1180–1185 AD). The five-year-long war concluded with a decisive Taira defeat in the naval Battle of Dan-no-Ura, which resulted in the deaths of Antoku and Taira leaders. Following the war, the victorious Minamoto established Japan's first shogunate in Kamakura. The name "Genpei" comes from alternate readings of the kanji "Minamoto" (源 Gen) and "Taira" (平 Hei).

The Genpei War (源平合戦, Genpei Kassen, Genpei-Gassen; 1180–1185) was a national civil war between the Taira and Minamoto clans during the late Heian period of Japan. It resulted in the downfall of the Taira and the establishment of the Kamakura shogunate under Minamoto no Yoritomo, who appointed himself as Shōgun in 1192, governing Japan as a military dictator from the eastern city of Kamakura.

It followed a coup d'état by the Taira in 1179 with the removal of rivals from all government posts, and subsequently banishing them, and a call to arms against the Taira, led by the Minamoto in 1180. The ensuing Battle of Uji took place just outside Kyoto, starting a five-year-long war, concluding with a decisive Minamoto victory in the naval Battle of Dan-no-ura. However, it has been pointed out that the Battle of Ōshū in 1189 was the last battle during this period of civil war, as it completed Yoritomo's nationwide domination through the annexation of Northeast Japan.
