Mitsumasa Kitabatake

Japanese: 北畠満雅 - きたばたけ・みつまさ

Year of death: 21 December 1429 (25 January 1429)
Year of birth: Year of birth unknown. Military commander of the Muromachi period. Eldest son of Kitabatake Akiyasu, governor of Ise Province. Became governor of Ise Province in 1402 (Oei 9). The character "Mitsu" in Mitsumasa's name is thought to be one of the characters in the name of Shogun Ashikaga Yoshimitsu, but he never compromised with the Muromachi Shogunate throughout his life, and continued to press for the fulfillment of the conditions for the unification of the Northern and Southern Courts. To Shogun Ashikaga Yoshinori, who aimed for the stability of the Shogunate system, Mitsumasa's existence was as much a threat as the Kamakura Kubo, and two military clashes occurred. The first was in 1414 (Oei 21). Mitsumasa raised an army in protest against the enthronement of Emperor Gokomatsu of the Jimyoin line and his son Emperor Shoko, and together with the local clans of Sawa and Akiyama of Uda County in Yamato, resisted the Shogunate forces, and eventually made peace. The second was in 1428 (Shocho 1). He rebelled against the agreement that Emperor Go-Hanazono (the adopted son of Emperor Go-Komatsu) would succeed Emperor Shoko, and supported Prince Ogura (Seisho), the grandson of Emperor Go-Kameyama, the last Emperor of the Southern Court. However, to no avail, Mitsumasa was defeated and killed in the battle of Iwata, Ano-gun (Tsu City) on December 21 of the same year, and the power of the Ise kokushi declined for a time.

室町時代の武将。伊勢国司北畠顕泰の長男。応永9(1402)年伊勢国司。満雅の「満」の字は将軍足利義満の諱の1字と考えられるが,室町幕府とは生涯妥協せず,南北両朝合体の条件履行を迫り続けた。幕府体制の安定を狙う将軍足利義教にとって,その存在は鎌倉公方と並ぶ脅威となり,2度にわたる軍事衝突が起こった。1度目は応永21(1414)年。満雅は,持明院統の後小松天皇のあとその子称光天皇が即位するのを違約として挙兵し,大和宇陀郡の国人沢・秋山両氏らと共に幕府軍に抵抗,やがて和した。2度目は正長1(1428)年。称光天皇のあと後花園天皇(後小松天皇の猶子)が即位するのを違約とし,南朝最後の後亀山天皇の孫小倉宮(聖承)を奉じて反旗を翻した。しかし利あらず,同年12月21日,安濃郡岩田(津市)の戦で満雅はついに敗死,その後,伊勢国司の勢力はしばらく衰えた。
