How three men ended 150 years of endless civil war

How Japan Ended Its Longest Civil War · 34:07 · Video: History Mapped Out · Watch at the source

In short: The Sengoku era was a period where no single warlord could achieve total victory. This video explores how the introduction of firearms and a sequence of three distinct leaders finally unified Japan.

The conflict began with the Onin War, creating a landscape of dozens of warring clans and a shogun with no real authority. While most daimyo dismissed Portuguese arquebuses as slow and impractical compared to traditional swordsmanship, Oda Nobunaga recognized their potential to turn peasants into effective soldiers in weeks rather than decades.

Nobunaga's rise was marked by the destruction of an army eight times his size and the burning of a monastery that had stood since the eighth century. After his assassination, Toyotomi Hideyoshi—a man born as a peasant—eliminated independent clans and disarmed the lower classes. Finally, Tokugawa Ieyasu seized total control in a single day at the Battle of Sekigahara, ushering in 250 years of peace.
