欽明天皇
Seinei was a 5th-century monarch. The reign of Emperor Kinmei ( – 571 AD), the 29th Emperor, is the first for which contemporary historiography is able to assign verifiable dates; however, the conventionally accepted names and dates of the early Emperors were not to be confirmed as "traditional" until the reign of Emperor Kanmu (737–806), the 50th sovereign of the Yamato dynasty.
