Matsudaira Hirotada

A military commander in the Sengoku period. The eighth head of the Mikawa Matsudaira clan. Lord of Okazaki Castle. Son of Kiyoyasu. Father of Tokugawa Ieyasu. When he was 10 years old, his father Kiyoyasu was stabbed to death by his retainer Abe Yashiro while marching to Owari Moriyama to fight against Oda Nobuhide. He was chased out of Okazaki Castle by his great-uncle Nobusada and wandered through Ise, Totomi, and Mikawa. Later, with the support of Imagawa Yoshimoto, he finally returned to Okazaki in 1537 (Tenbun 6), but even after that, the Matsudaira clan continued to have internal conflicts with the Imagawa and Oda forces as their backing. In the midst of all this, in 1541 he married the daughter (Odai) of Mizuno Tadamasa, lord of Kariya Castle in Mikawa, and the following year Takechiyo (Ieyasu) was born. After that, in 1545 he attacked Anjo Castle, and in 1547 he captured Tahara Castle, the stronghold of Toda Yasumitsu, but when Oda Nobuhide attacked, he took Takechiyo hostage and asked Imagawa Yoshimoto for help. It was at this time that Takechiyo was captured by Toda Yasumitsu near Tahara on his way to Sunpu, and sent to the Oda clan. He later devoted himself to the subjugation of Mikawa, but in March of 1555 he was stabbed to death by his trusted vassal Iwamatsu Hachiya.

戦国時代の武将。三河(みかわ)松平家8代目。岡崎城主。清康(きよやす)の子。徳川家康の父。10歳のときに父清康が織田信秀(のぶひで)と戦うため、尾張守山(おわりもりやま)へ出陣中に家臣の阿部弥七郎(やしちろう)に刺殺（守山崩れ）されたため、大叔父信定(のぶさだ)に岡崎城を追われ、伊勢(いせ)、遠江(とおとうみ)、三河を流浪。のち今川義元(よしもと)の後援を受け、1537年（天文6）ようやく岡崎に帰ったが、以後も松平家では今川・織田勢力を背景に内紛が続いた。そうしたなかで41年、三河刈谷(かりや)城主水野忠政(ただまさ)の女(むすめ)（於大(おだい)）と結婚、翌年に竹千代(たけちよ)（家康）が生まれた。その後45年安祥(あんじょう)城を攻め、47年には戸田康光(やすみつ)の拠(よ)る田原(たはら)城を陥れたが、織田信秀の来攻に際し、竹千代を人質として今川義元に救援を求めた。竹千代が駿府(すんぷ)に赴く途中、田原付近で戸田康光に奪われ、織田氏のもとへ送られたのはこのときである。のち三河平定に尽くしたが、天文(てんぶん)18年3月、近臣岩松八弥(いわまつはちや)に刺殺された。
