Sengoku in the context of "Kyōtoku incident"

Daimyo (大名, daimyō; English: /ˈdaɪm.joʊ/, Japanese: [dai.mʲoꜜː] ) were powerful Japanese magnates, feudal lords who, from the 10th century to the early Meiji period in the middle 19th century, ruled most of Japan from their vast hereditary land holdings. They were subordinate to the shogun and nominally to the emperor and the kuge (an aristocratic class). In the term, dai (大) means 'large', and myō stands for myōden (名田), meaning 'private land'.

From the shugo of the Muromachi period through the Sengoku period to the daimyo of the Edo period, the rank had a long and varied history. The backgrounds of daimyo also varied considerably; while some daimyo clans, notably the Mōri, Shimazu and Hosokawa, were cadet branches of the Imperial family or were descended from the kuge, other daimyo were promoted from the ranks of the samurai, notably during the Edo period.

Matsukura Shigemasa (松倉 重政; 1574 – December 19, 1630) was a Japanese feudal lord of the late Sengoku and early Edo periods. He held the title of Bingo no Kami and the Imperial court rank of junior 5th, lower grade (ju-go i no ge). Though he began as a retainer of Tsutsui Sadatsugu of Yamato Province, he became a lord in his own right, acquiring the 60,000 koku Shimabara Domain in Kyushu, in 1600. He is most famous for being the lord whose domain was the center of the Shimabara Rebellion of 1638.

The Ogasawara clan (Japanese: 小笠原氏, Hepburn: Ogasawara-shi) was a Japanese samurai clan descended from the Seiwa Genji. The Ogasawara acted as shugo (governors) of Shinano Province during the Sengoku period (c. 1185–1600), and as daimyō (feudal lords) of territories on Kyūshū during the Edo period (1600–1867).

During the Kamakura and Muromachi periods, the clan controlled Shinano province, while related clans controlled the provinces of Awa, Bizen, Bitchū, Iwami, Mikawa, Tōtōmi and Mutsu. According to some theories, the Miyoshi clan and the Mizukami clan were descendants of the Ogasawara clan.
