Date Tanemune

Japanese: 伊達稙宗 - だて・たねむね

Year of death: June 19, 1565 (July 16, 1565)
Year of birth: 1488
A military commander in the Sengoku period. Son of Naomune, his mother was the daughter of Uesugi Sadazane, the Shugo of Echigo. His first name was Shojiro, and he was given one character of the name Tanemune by Shogun Ashikaga Yoshitane. He was a Junior Fourth Rank, Lower. During the Eikyo era (1504-21), he engaged in conflict with the neighboring Mogami clan, and in 1522 he was appointed to the unprecedented post of Mutsu Shugoshoku and Sakyo no Daibu, and in 1532 he moved from Yanagawa Castle to Koori Nishiyama Castle. He also played a groundbreaking role in the establishment of the Date clan's power as a Sengoku daimyo, by creating and enacting the Muneyaku Nikki in 1543, the national law Chinkaishu in 1545, and the Danzencho in 1546. On the other hand, he caused resentment within the clan by strengthening the imposition of Muneyaku and Danzen, which became a factor in the Tenbun Rebellion (1558-1559). The direct cause of this rebellion was a conflict between Tanemune and Harumune, father and son, over the succession of Tanemune's third son, Sanemoto, to the Uesugi clan, the guardian of Echigo. Tanemune was defeated in this conflict and retired to Marumori Castle in Igu County. He had many children, who were successors and married into various families in Soma, Ashina, Osaki, Kasai, Nikaido, Tamura, and Kakeda, and he established a strong foothold in central and southern Oshu. He also enjoyed waka poetry (he was also called Juten). He was buried at Shoonji Temple in Marumori. His grave is at Yorinji Temple in Fukushima City.

戦国時代の武将。尚宗の子,母は越後守護上杉定実の娘。初名は称次郎,将軍足利義稙から1字を拝領して稙宗。従四位下。永正年間(1504～21)には隣接する最上氏と抗争を展開,大永2(1522)年には前例のない陸奥守護職,左京大夫に補任され,天文1(1532)年には梁川城から桑折西山城に移る。さらに天文4年『棟役日記』,5年分国法『塵芥集』,7年『段銭帳』を作成,制定するなど,伊達氏の戦国大名権力成立に画期的役割を果たす。しかし半面,棟役,段銭賦課の強化により家中の反発を招き,天文の乱(天文11～17年)の要因をつくる。この乱は越後守護上杉氏に稙宗3男実元を入嗣させることをめぐって,稙宗,晴宗父子が対立したのが直接の原因であった。この争乱で敗れた稙宗は伊具郡丸森城に隠居。子どもが多く,相馬,蘆名,大崎,葛西,二階堂,田村,懸田などの諸家に入嗣,入嫁させ,奥羽中南部に強固な地歩を築く。和歌も好む(受天とも号した)。丸森松音寺に葬る。墓は福島市の陽林寺。
