Emperor Gosuzaku

An emperor in the late Heian period (reigned 1036-45). His name was Atsunaga. He was the third son of Emperor Ichijo. His mother was Jotomon'in Shoshi, the daughter of Fujiwara no Michinaga. At the time, political leadership had been passed on from Michinaga to his son Yorimichi, but the heyday of the regent family had passed. In 1040 (Chōkyū 1), he proposed an order to consolidate manors, the contents of which were inherited by the later Kantoku and Enkyū consolidation orders. When he handed over the throne to his son (Emperor Goreizei) due to illness, he overrode Yorimichi's opposition and appointed Prince Takahito (later Emperor Gosanjo) as the new emperor's younger brother, paving the way for the cloistered government. He died on January 18, 2nd year of the Kantoku era. His tomb is at Enjoji Mausoleum in Kyoto.

平安後期の天皇（在位1036～45）。名は敦良(あつなが)。一条(いちじょう)天皇の第3皇子。母は藤原道長(みちなが)の娘上東門院彰子(じょうとうもんいんしょうし)。当時、政治の主導権は道長から子頼通(よりみち)に引き継がれていたが、摂関家(せっかんけ)の全盛期は過ぎていた。1040年（長久1）に、実施はされなかったらしいが、荘園(しょうえん)整理令を発議、この内容は後の寛徳(かんとく)・延久(えんきゅう)の整理令に継承されるもととなっている。病気により位を子に譲ると（後冷泉(ごれいぜい)天皇）、頼通の反対を押し切って尊仁(たかひと)親王を新帝の皇太弟(こうたいてい)に定め（後の後三条(ごさんじょう)天皇）、院政への道を開いた。寛徳2年1月18日死去。陵墓は京都円乗寺陵。
