Southern CourtThe Southern Court were a set of four emperors (Emperor Go-Daigo and his line) whose claims to sovereignty during the Nanboku-chō period spanning from 1336 through 1392 were usurped by the Northern Court. This period ended with the Southern Court definitively losing the war, and they were forced to completely submit sovereignty to the Northern Court. This had the result that, while later Japanese sovereigns were descended from the Northern Court, posterity assigns sole legitimacy during this period to the Southern Court.
Hakuhō periodThe Hakuhō period was an unofficial Japanese era name of Emperor Tenmu after Hakuchi and before Suchō. The duration of this discrete non-nengō timespan lasted from 673 through 686. The Hakuhō period is more often used as a general term which describes a wider range of years. Hakuhō is conventionally used to identify a broad historical and artistic period of the late seventh century and early eighth century. The term is primarily used in art history and is thought to have been introduced at the 1910 Japan–British Exhibition.
Boshin WarThe Boshin War, sometimes known as the Japanese Revolution or Japanese Civil War, was a civil war in Japan fought from 1868 to 1869 between forces of the ruling Tokugawa shogunate and a coalition seeking to seize political power in the name of the Imperial Court. The war stemmed from dissatisfaction among many nobles and young samurai with the shogunate's handling of foreigners following the opening of Japan during the prior decade. Increasing Western influence in the economy led to a decline similar to that of other Asian countries at the time.
Edo periodThe Edo period or Tokugawa period is the period between 1603 and 1867 in the history of Japan, when Japan was under the rule of the Tokugawa shogunate and the country's 300 regional daimyo. Emerging from the chaos of the Sengoku period, the Edo period was characterized by economic growth, strict social order, isolationist foreign policies, a stable population, perpetual peace, and popular enjoyment of arts and culture, colloquially referred to as Oedo.
Meiji eraThe Meiji era is an era of Japanese history that extended from October 23, 1868 to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudal society at risk of colonization by Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas.
Heian periodThe Heian period 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). 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 and noted for its art, especially poetry and literature.
Taika ReformThe Taika Reforms were a set of doctrines established by Emperor Kōtoku (孝徳天皇 Kōtoku tennō) in the year 645. They were written shortly after the death of Prince Shōtoku and the defeat of the Soga clan (蘇我氏 Soga no uji), uniting Japan. The reforms also artistically marked the end of the Asuka period and the beginning of the Hakuhō period. Crown Prince Naka no Ōe (the future Emperor Tenji), Nakatomi no Kamatari, and Emperor Kōtoku jointly embarked on the details of the Reforms.
