[SEP] Knowledge 2: Fujiwara no Yoritada
Fujiwara no Yoritada (藤原 頼忠; 924 – 31 July 989), the second son of Saneyori, was a kugyo (high-ranked Japanese noble) who served as regent for Emperor En'yū and Emperor Kazan.His mother was a daughter of Fujiwara no Tokihira.His elder brother from the same mother Atsutoshi died before their father's death.In 977 he became Sadaijin, and when his cousin, the regent Fujiwarano Kanemichi was in a critical medical condition, he ceded the position of Kampaku (regent) to Yoritada, instead of his rival brother Kaneie.Although Yoritada's two daughters were consorts of Emperor En'yū and Emperor Kazan, they did not have any sons.Yoritada thus had only a tenable blood relationship with the Emperors.His cousin Kaneie was the grandfather of Crown Prince Yasuhito (Emperor Ichijō), and he encouraged Emperor Kazan to abdicate a throne.By the accession of Emperor Ichijō, Yoritada retired from his post as Kampaku, and Kaneie became Sessho (regent) for his grandson Emperor Ichijō.Yoritada was Daijō Daijin from 978, and he is referred to as Rengi-kō (廉義公)(posthumous name of Daijō Daijin).His poet son Fujiwara no Kintō compiled the "Shūi Wakashū", and also a collection of Chinese verse and prose (~600 selections) and 25 Japanese poems in his "Wakan Rōeishū" (和漢朗詠集), a widely admired collection that helped spread the influence of Chinese culture (and especially the poetry of Bai Juyi) in the Japanese Imperial court.Kintō's collection would be imitated by a successor, Fujiwara no Mototoshi's "Shinsen Rōeishū" (新撰朗詠集).Kintō also wrote an influential critical guide to incorporating Bai Juyi's poetic techniques (and more generally, T'ang dynasty poetry) into Japanese poetry called "Shinsen Zuinō" (新撰髄脳) ("The Essence of Poetry Newly Selected").

Fujiwara no Morozane( Japanese language: 藤原 師実 ふじわらの もろざね)( 1042 – March 14, 1101) was a regent of Japan and a chief of the Fujiwara clan during the late Heian period.He was known as Kyōgoku dono( Lord Kyōgoku) or Go- Uji dono( the Later Lord Uji, 後宇治殿).He held the positions of sessho or kanpaku for a twenty- year period, sessho from 1075 to 1086 during the reign of Emperor Shirakawa and from 1094 to 1099 during the reign of Emperor Horikawa, and kampaku from 1086 to 1094 during the reign of Emperor Horikawa.He was the son of Fujiwara no Yorimichi and Fujiwara no Gishi( 藤原 祇子, her real name is unknown today), a daughter of Fujiwara no Tanenari( 藤原 種 成), hence the grandson of Fujiwara no Michinaga.A contemporary document suggested he was the third born son, but this is uncertain.He was appointed to the positions of sadaijin, sessho and kampaku.He made his adopted daughter Kenshi( 賢子) a consort of Emperor Shirakawa.Kenshi died when she was very young, but she left a son who would later ascend to the throne as Emperor Horikawa.Emperor Shirakawa seized political power and Morozane was unable to enjoy the monopolic power that his father and grandfather had enjoyed.Even after Emperor Horikawa reached adulthood, the cloistered Emperor Shirakawa seized power.Morozane married Fujiwara no Reishi, who was a daughter of Minamoto no Morofusa, a grandson of Emperor Murakami, and later adopted by Fujiwara no Nobuie.Morozane had many sons and daughters, including Fujiwara no Moromichi and Fujiwara no Ietada.From Morozane, two kuge families derive, the Kazanin family and the Oimikado( Oinomikado) family.Morozane is also known the author of the waka collection" Kyōgoku Kanpakush ū"( Anthology of Kyōgoku Kanpaku) and the diary" Kyōgoku Kanpaku- ki"( Diary of Kyōgoku Kanpaku).
