Ashikaga Takauji in the context of "Kamakura Shogunate"

The Muromachi period or Muromachi era (室町時代, Muromachi jidai), also known as the Ashikaga period or Ashikaga era (足利時代, Ashikaga jidai), is a division of Japanese history running from approximately 1336 to 1573. The period marks the governance of the Muromachi or Ashikaga shogunate (Muromachi bakufu or Ashikaga bakufu), which was officially established in 1338 by the first Muromachi shōgun, Ashikaga Takauji, two years after the brief Kenmu Restoration (1333–1336) of imperial rule was brought to a close. The period ended in 1573 when the 15th and last shogun of this line, Ashikaga Yoshiaki, was driven out of the capital in Kyoto by Oda Nobunaga.

From a cultural perspective, the period can be divided into the Kitayama and Higashiyama cultures (later 15th – early 16th centuries).

The Kamakura shogunate (Japanese: 鎌倉幕府, Hepburn: Kamakura bakufu) was the feudal military government of Japan during the Kamakura period from 1185 to 1333.

The Kamakura shogunate was established by Minamoto no Yoritomo after victory in the Genpei War and appointing himself as shōgun. Yoritomo governed Japan as military dictator from the eastern city of Kamakura with the emperor of Japan and his Imperial Court in the official capital city of Heian-kyō (Kyoto) as figureheads. The Kamakura shōguns were members of the Minamoto clan until 1226, the Fujiwara clan until 1252, and the last six were minor princes of the imperial family. The Hōjō clan were the de facto rulers of Japan as shikken (regent) of the shōgun from 1203. The Kamakura shogunate saw the Jōkyū War in 1221 and the Mongol invasions of Japan under Kublai Khan in 1274 and 1281. The Kamakura shogunate was overthrown in the Kenmu Restoration under Emperor Go-Daigo in 1333, re-establishing Imperial rule until Ashikaga Takauji and his offspring overthrew the imperial government and founded the Ashikaga shogunate in 1336 (Nanboku-chō period).

Kanrei (管領) or, more rarely, kanryō, was a high political post in feudal Japan; it is usually translated as shōgun's deputy. After 1349, there were actually two Kanrei, the Kyoto Kanrei and the Kantō Kanrei. But originally from 1219 until 1333, the post was synonymous with the Rokuhara Tandai, and was based in Kyoto. The Hōjō clan monopolized this post, and there were during this period two Deputies – a southern chief, and a northern chief. From 1336 to 1367, the Deputy was called Shitsuji (執事). The first to hold this title was Kō no Moronao.

Following the fall of the Kamakura shogunate and abolition of the Rokuhara Tandai position, both occurring in 1333, Ashikaga Takauji created the post of Kantō Kanrei, or Shogun's Deputy in the East (Kantō generally refers to the area around and including modern Tokyo).

The Ashikaga shogunate (足利幕府, Ashikaga bakufu), also known as the Muromachi shogunate (室町幕府, Muromachi bakufu), was the feudal military government of Japan during the Muromachi period from 1336 to 1573.

The Ashikaga shogunate was established when Ashikaga Takauji was appointed Shōgun after overthrowing the Kenmu Restoration shortly after it had overthrown the Kamakura shogunate in support of Emperor Go-Daigo. The Ashikaga clan governed Japan from the Imperial capital of Heian-kyō (Kyoto) as de facto military dictators along with the daimyō lords of the samurai class. The Ashikaga shogunate began the Nanboku-chō period between the Pro-Ashikaga Northern Court in Kyoto and the Pro-Go-Daigo Southern Court in Yoshino until the South conceded to the North in 1392. The Ashikaga shogunate collapsed upon outbreak of the Ōnin War in 1467, entering a state of constant civil war known as the Sengoku period, and was finally dissolved when Shōgun Ashikaga Yoshiaki was overthrown by Oda Nobunaga in 1573.

The Kenmu Restoration (Japanese: 建武の新政, Hepburn: Kenmu no shinsei) was a three-year period of Imperial rule in Japanese history between the Kamakura period and the Muromachi period from 1333 to 1336. The Kenmu Restoration was an effort made by Emperor Go-Daigo to overthrow the ruling Kamakura Shogunate (de facto ruled by Hōjō clan) and restore the Imperial House to power in Japan, returning to civilian government after 148 years of de facto military government from Kamakura. Go-Daigo launched the Genkō War in 1331 against the Kamakura Shogunate but was defeated and forced to exile to the Oki Islands. Go-Daigo launched a second uprising, and with the assistance of the defected Kamakura general Ashikaga Takauji and rebel leader Nitta Yoshisada, defeated the Kamakura Shogunate at the siege of Kamakura in 1333. The Imperial House was restored to power but Go-Daigo's policies failed to satisfy his major samurai supporters and most Japanese people. The Kenmu Restoration was ultimately overthrown when Takauji became Shōgun and founded the Ashikaga Shogunate in 1336, beginning the "Northern and Southern Courts" period and the Muromachi period.

The Kenmu Restoration was the last time the Emperor of Japan held significant power until the Meiji Restoration in 1868.

The Seiwa Genji (清和源氏; Japanese pronunciation: [sei.wa ɡeꜜɲ.dʑi, seː-]) is a line of the Japanese Minamoto clan that is descended from Emperor Seiwa, which is the most successful and powerful line of the clan. Many of the most famous Minamoto members, including Minamoto no Yoshitsune, Minamoto no Yoritomo, the founder of the Kamakura shogunate; and Ashikaga Takauji, the founder of the Ashikaga shogunate, belonged to this line. Tokugawa Ieyasu (1543–1616), founder of the Tokugawa shogunate, also claimed descent from this lineage. The family is named after Emperor Seiwa, whose four sons and twelve grandsons founded the Seiwa Genji. Emperor Seiwa was father of Imperial Prince Sadazumi (貞純親王 Sadazumi Shinnō) (873–916), who was in turn the father of Minamoto no Tsunemoto (源経基) (894–961), one of the founders of the Seiwa Genji, from whom most Seiwa Genji members are descended. Many samurai families belong to this line and used "Minamoto" clan name in official records, such as the Ashikaga, Hatakeyama, Hosokawa, Imagawa, Mori, Nanbu, Nitta, Ogasawara, Ōta, Satake, Satomi, Shiba, Takeda, Toki and the Tsuchiya, among others. The Shimazu and Tokugawa clans also claimed to belong to this line.

A group of Shinto shrines connected closely with the clan is known as the Three Genji Shrines (源氏三神社 Genji San Jinja).

Emperor Go-Daigo (後醍醐天皇 Go-Daigo-tennō) (26 November 1288 – 19 September 1339) was the 96th emperor of Japan, according to the traditional order of succession. He successfully overthrew the Kamakura shogunate in 1333 and established the short-lived Kenmu Restoration to bring the Imperial House back into power. This was to be the last time the emperor had real power until the Meiji Restoration in 1868. The Kenmu restoration was in turn overthrown by Ashikaga Takauji in 1336, ushering in the Ashikaga shogunate. The overthrow split the imperial family into two opposing factions between the Ashikaga backed Northern Court situated in Kyoto and the Southern Court based in Yoshino. The Southern Court was led by Go-Daigo and his later successors.

Kō no Moronao (高 師直; died 24 March 1351, also Moronō) was a Japanese samurai of the Nanboku-chō period who was the first to hold the position of Shitsuji (Shōgun's Deputy). He was appointed by Ashikaga Takauji, the first shōgun of the Ashikaga shogunate. As Deputy, he served not only an administrative governmental function, but also as general of the Shogun's armies. He fought for the Ashikaga against the loyalist forces of the Southern Court during the wars of the Nanboku-chō period and killed its generals Kitabatake Akiie and Kusunoki Masayuki.

Moronao was an iconoclast with no intention of following tradition, particularly insofar as the Emperor was concerned. On the subject, he once said:
