Sadatake Ise

A family of the late Edo period. He marked a period in particular in the study of samurai traditions. He was a shogunate official. He was known as Heizo, and his given names were Teijo, Anzai, and Ginkei. Since the Muromachi Shogunate, the Ise clan, along with the Ogasawara and Imagawa clans, have been involved in samurai ceremonies and traditional customs, and this tradition was called the Ise style. Sadamasu's father, Sadamasu, inherited a family stipend of 1,000 koku, and in 1717 (the second year of the Kyoho era), he prepared 52 copies and 63 volumes of the family's traditional texts for inspection by the 8th Shogun, Tokugawa Yoshimune, but died in 1725 at the young age of 33, and his successor, his older brother Sadanobu, also died at the early age of 13, and the family line was tragically cut off. In August of the following year (1803), by special decree, 10-year-old Sadatake was allowed to succeed the family name, but his family stipend was drastically reduced to just 300 koku.

This unrest and decline in the knowledge of the head family accelerated the decline of the Ise school, which had already been overwhelmed by the Ogasawara school since around the Genroku period (1688-1704), but this only increased the family's expectations of the young and talented Sadatake. Sadatake was a man of great learning and knowledge, having read through the abundant family books and well versed in the traditions of the imperial court and the military, and in 1745 (Enkyo 2) he was ranked as a guard in the Okosho group, raising the family's name. He continued to dedicate himself to research, and his writings, covering subjects such as the samurai system, symbols, archery and horseback riding, weapons and equipment, and clothing, number in excess of 300 copies. Among his most famous works are "Teijo Miscellaneous Notes," "Anzai Essays," "Anzai Miscellaneous Notes," "Anzai Novels," "Weapons Research," "One Hundred Poems on Military Weapons," "Military Records," "Seasonal Flowers," "Personal Notes," "Ise Archery and Horse Studies Series," and "Ise Heizo Family Precepts."

江戸中期の故実家。とくに武家故実の研究に一時期を画した。幕臣。通称平蔵、名は貞丈（「ていじょう」とも）、安斎、銀卿(ぎんけい)と号す。伊勢氏は室町幕府以来、小笠原(おがさわら)、今川両氏と並んで武家諸礼式、故実を家職とし、その伝統を伊勢流と称した。貞丈の父貞益(さだます)は家禄(かろく)の1000石を継ぎ、1717年（享保2）には8代将軍徳川吉宗(よしむね)の命により家伝の書52部・63巻を台覧に備えたが、25年、33歳の若さで死去し、その跡を継いだ兄貞陳(さだのぶ)もまた13歳で夭折(ようせつ)し、一家断絶の悲運にみまわれた。翌26年8月に至り、特旨により10歳の貞丈が家名を継ぐことを許されたが、家禄は大幅に削減されて、わずか300石を給せられた。

　こうした宗家の動揺・減知は、すでに元禄(げんろく)（1688～1704）前後から小笠原流に圧せられた伊勢流の退勢に拍車をかけたが、それだけに年少気鋭の貞丈にかける一門の期待は大きかった。貞丈は博覧強記、家伝の豊富な書籍を読破し、よく公武の故実に通じ、1745年（延享2）御小姓組(おこしょうぐみ)番士に列し、家名をあげた。その後も研究に専念し、その著述は武家の制度、典章、弓馬、武器武具、服飾などの分野に及び、実に300部を数える。そのうち『貞丈雑記』『安斎随筆』『安斎雑考』『安斎小説』『武器考証』『軍器考百首』『軍用記』『四季草』『座右書』『伊勢弓馬叢書(そうしょ)』『伊勢平蔵家訓』などが著名である。
