The circle indicates the time we are discussing in this section.

 

After Jokyu-no-Ran (11|Jokyu-no-ran ), the power of the Imperial court declined significantly.  The Hojo clan (the main power during the Kamakura period) began to have financial difficulty and started to lose control over the local lords.  One of the reasons was the cost incurred by the Mongolian invasion.  The Kamakura Bakufu (government) could not reward well to the local lords who worked hard at this war. The local lords became very dissatisfied with the Kamakura Bakufu.  Seeing this as a chance, Emperor Go-Daigo attempted to attack Kamakura Bakufu two times but failed both times.  He was exiled to Oki island.  Meantime, Ashikaga Takauji (足利尊氏) and several other groups of Samurai who were opposing the Kamakura Bakufu, gathered their power and succeeded in destroying the Kamakura Bakufu (1333).  This ends the Kamakura period.  Emperor Go-Daigo, who had been exiled to Oki island returned to Kyoto and attempted established a political reforms.  This is called Kenmu-no-Chuko (建武の中興).  But this new policy failed to satisfy most of the ruling class.  Taking advantage of this situation, Ashikaga Takauji attacked the Imperial court in Kyoto, deposed Emperor Go-Daigo and placed the other branch of the Royal family on the Imperial throne.  But the Emperor Go-Daigo insisted upon his legitimacy, moved to Yoshino (located the South of Kyoto) and established a rival Imperial court.  Thus began the North and the South dynasty.  After much strife between the North and the South, together with the problems within themselves,  eventually more Samurai groups went under the control of the North dynasty.  About 60 years later, the Southern dynasty was compelled to accept the North Dynasty’s proposal.  As a result, North Dynasty established as the legitimate imperial court.  This 60 year is the time called Nanboku-Cho or Yoshino-Cho period.  During the Nanboku-Cho period, Samurai demanded larger and showy, and practical swords.  Soshu Den was its height of their prominence.  However,  Soshu group was not the only group that made all the swords. Other schools and other provinces also made Soshu Den style swords.
