Nanboku-chō period

The Nanboku-chō period (南北朝時代 Nanboku-chō jidai^?, "South and North courts period", also known as the Northern and Southern Courts period), spanning from 1336 to 1392, was a period that occurred during the formative years of the Muromachi bakufu of Japan's history.

During this period, there existed a Northern Imperial Court, established by Ashikaga Takauji in Kyoto, and a Southern Imperial Court, established by Emperor Go-Daigo in Yoshino.
Ideologically, the two courts fought for fifty years, with the South giving up to the North in 1392. However, in reality the Northern line was under the power of the Ashikaga shoguns and had little real independence.

Since the 19th century the Emperors of the Southern Imperial Court have been considered the legitimate Emperors of Japan. Other contributing factors were the Southern Court's control of the Japanese imperial regalia, and Kitabatake Chikafusa's work Jinnō Shōtōki, which legitimized the South's imperial court despite their defeat.

The consequences of events in this period continue to be influential in modern Japan's conventional view of the Tennō Seika (Emperor system).

The term bakufu originally meant the dwelling and household of a shogun, but in time it came to be generally used for the system of government of a feudal military dictatorship, exercised in the name of the shogun; and this is the meaning that has been adopted into English through the term 'shogunate'.
