Kuge in the context of "Northern Fujiwara"

Daimyo (大名, daimyō; English: /ˈdaɪm.joʊ/, Japanese: [dai.mʲoꜜː] ) were powerful Japanese magnates, feudal lords who, from the 10th century to the early Meiji period in the middle 19th century, ruled most of Japan from their vast hereditary land holdings. They were subordinate to the shogun and nominally to the emperor and the kuge (an aristocratic class). In the term, dai (大) means 'large', and myō stands for myōden (名田), meaning 'private land'.

From the shugo of the Muromachi period through the Sengoku period to the daimyo of the Edo period, the rank had a long and varied history. The backgrounds of daimyo also varied considerably; while some daimyo clans, notably the Mōri, Shimazu and Hosokawa, were cadet branches of the Imperial family or were descended from the kuge, other daimyo were promoted from the ranks of the samurai, notably during the Edo period.

Samurai (侍) were members of the warrior class who served as retainers to lords in Japan prior to the Meiji era. Samurai existed from the late 12th century until their abolition in the late 1870s during the Meiji era. They were originally provincial warriors who served the Kuge and imperial court in the late 12th century.

In 1853, the United States forced Japan to open its borders to foreign trade under the threat of military action. Fearing an eventual invasion, the Japanese abandoned feudalism for capitalism so that they could industrialize and build a modern army. The adoption of modern firearms rendered the traditional weapons of the samurai obsolete, and as firearms are easy enough for peasant conscripts to learn, Japan had no more need for a specialized warrior caste. By 1876 the special rights and privileges of the samurai had all been abolished.

The Imperial Court in Kyoto was the nominal ruling government of Japan from 794 AD until the Meiji period (1868–1912), after which the court was moved from Kyoto (formerly Heian-kyō) to Tokyo (formerly Edo) and integrated into the Meiji government. Upon the court being moved to Kyoto from Nagaoka by Emperor Kanmu (737–806), the struggles for power regarding the throne that had characterized the Nara period diminished. Kyoto was selected as the location for the court because of its "proper" amount of rivers and mountains which were believed to be the most auspicious surroundings for the new capital. The capital itself was built in imitation of Chang'an, the Chinese capital of the Tang dynasty, closely following the theories of yin-yang. The most prominent group of people within the court was the civil aristocracy (kuge) which was the ruling class of society that exercised power on behalf of the emperor.

Kyoto's identity as a political, economic, and cultural centre started to be challenged in the post-1185 era with the rise of the shogunate system which gradually seized governance from the emperor. Minamoto no Yoritomo was the first to establish the post of the shōgun as hereditary, receiving the title in 1192. After Yoritomo launched the shogunate, true political power was in the hand of the shōguns, who were mistaken several times for the emperors of Japan by representatives of Western countries. The Kamakura shogunate (or Kamakura bakufu) would go on to last for almost 150 years, from 1185 to 1333.

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.

The Kazoku (華族, "Magnificent/Exalted lineage"; IPA: [ka̠zo̞kɯ̟]) was the hereditary peerage of the Empire of Japan, which existed between 1869 and 1947. It was formed by merging the feudal lords (daimyō) and court nobles (kuge) into one system modelled after the British peerage. Distinguished military officers, politicians, and scholars were occasionally ennobled as (新華族, shin kazoku, 'the newly ennobled'), until the country's defeat in the Second World War in 1945. The system was abolished with the 1947 constitution, which prohibited any form of aristocracy under it, but kazoku descendants still form the core of the traditional upper class in the country's society, distinct from the nouveau riche.

Kazoku (華族) should not be confused with kazoku (家族), which is pronounced the same in Japanese, but written with different characters, meaning "immediate family" (as in the film Kazoku above).

This is a list of Japanese clans. The old clans (gōzoku) mentioned in the Nihon Shoki and Kojiki lost their political power before the Heian period, during which new aristocracies and families, kuge, emerged in their place. After the Heian period, the samurai warrior clans gradually increased in importance and power until they came to dominate the country after the founding of the first shogunate.

Japan traditionally practiced cognatic primogeniture, or male-line inheritance in regard to passing down titles and estates. By allowing adult adoption, or for men to take their wife's name and be adopted into her family served as a means to pass down an estate to a family without any sons, Japan has managed to retain continuous family leadership for many of the below clans, the royal family, and even ordinary family businesses.

The Tachibana clan (橘氏, Tachibana-uji, Tachibana-shi) was one of the four most powerful court nobility (kizoku or kuge) families in Japan's Nara and early Heian periods—the other three were the Minamoto, the Fujiwara, and the Taira. Members of the Tachibana family often held high court posts within the Daijō-kan (Ministry of State), most frequently Sadaijin (Minister of the Left). Like the other major families at court, they also constantly sought to increase and secure their power by marrying into the imperial family. However, as the Minamoto clan and the Fujiwara clan gained power over the course of the 9th and 10th centuries, the Tachibana were eclipsed and eventually became scattered across the country. Though serving in high government posts outside the capital, they were thus denied the degree of power and influence within the court at Kyoto (Heian-kyō) which they once enjoyed.

The name of Tachibana was bestowed on Agata-no-Inukai no Michiyo by Empress Genmei in 708. She was the wife of Prince Minu, a descendant of Emperor Bidatsu and mothered Princes Katsuragi and Sai. She later married Fujiwara no Fuhito and bore Kōmyōshi (Empress Kōmyō). In 736, Princes Katsuragi and Sai were given the surname Tachibana, renouncing their imperial family membership. They became Tachibana no Moroe and Tachibana no Sai respectively.
