Sengoku period
The Sengoku period (戦国時代, Sengoku jidai; Japanese pronunciation: [seŋ.ɡo.kɯ (d)ʑiꜜ.dai, -ŋo.kɯ-] lit. 'Warring States period') was the period in Japanese history in which civil wars and social upheavals took place almost continuously in the 15th and 16th centuries. The Kyōtoku incident (1454), Ōnin War (1467), or Meiō incident (1493) are generally chosen as the period's start date, but there are many competing historiographies for its end date, ranging from 1568, the date of Oda Nobunaga's march on Kyoto, to the suppression of the Shimabara Rebellion in 1638, deep into what was traditionally considered the Edo period.
