Genki (era) in the context of "Daimyo"

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.

Eiroku (永禄) was a Japanese era name (年号, nengō; "year name") after Kōji and before Genki. This period spanned the years from February 1558 through April 1570. The reigning emperor was Ōgimachi-tennō (正親町天皇).

Tenshō (天正) was a Japanese era name (年号, nengō; "year" name) after Genki and before Bunroku. This period spanned the years from July 1573 through December 1592 during the Sengoku era. The reigning emperors were Ōgimachi-tennō (正親町天皇) and Go-Yōzei-tennō (後陽成天皇).
