Origins & Early Life

Emperor Uda (宇多天皇, Uda-tennō; June 10, 866 – September 3, 931) was the 59th emperor of Japan, according to the traditional order of succession. Uda's reign spanned the years from 887 through 897. Before his ascension to the Chrysanthemum Throne, his personal name (imina) was Sadami (定省) or Chōjiin-tei. Emperor was the seventh son of Emperor Kōkō, and his mother was Empress Dowager Hanshi (daughter of Prince Nakano, son of Emperor Kanmu). His father, Emperor Kōkō, was the great-uncle of the previous Emperor Yōzei.

Career & Major Achievements

Having ascended the throne after Yōzei was forced to abdicate, Emperor Kōkō felt that the throne should return to the legitimate line, such as Prince Sadayasu, Emperor Yōzei's younger brother by the same mother, and in June 884, he bestowed the surname Minamoto upon 26 princes and princesses in his own direct line, demoting them to commoner status. Prince Sadami was one of them, and was known as Minamoto no Sadami. However, before could formally proclaim a successor, Kōkō fell seriously ill in 887, three years after his enthronement. Regent Fujiwara no Mototsune stated that the emperor's preference was for Sadami rather than Sadayasu. Sadayasu was close to the main line of the imperial family and was also Mototsune's nephew, but his mother, Fujiwara no Takaiko, was not on good terms with Mototsune, despite being their full sister, so he was avoided.

Enduring Legacy & Impact

On the other hand, Mototsune himself was not particularly fond of Sadami, but Sadami was the adopted son of Mototsune's close half-sister, Fujiwara no Yoshiko, and Yoshiko, who had strong influence in the imperial court as a Naishi no Kami (a lady-in-waiting to the emperor), strongly recommended him, so the court decided. There were also problems with the younger brother Sadami succeeding to the throne ahead of his older brother Minamoto no Koretada, so the emperor accepted the recommendation submitted by Mototsune and other ministers and appointed him as Crown Prince. On August 25, Sadami was reinstated as a member of the imperial family and received the title of Imperial Prince. The following day, the 26th, he was appointed Crown Prince, but on that same day, Emperor Kōkō died, so Sadami ascended the throne and was officially enthroned on November 17. Emperor Uda lacked experience, and Fujiwara no Mototsune who had served as regent for four generations, held all political power.
