The Sengoku Period was a time of unrivalled conflict and disunity in medieval Japan. It spanned from 1467 to 1615 and was named by historians who compared it to the most warlike period in Ancient Chinese history: the Age of the Warring States.

Nobunaga seized this opportunity to turn the tides of the battle; Yoshimoto was killed, and Nobunaga instantly rose in power.
