The Genpei War pitted the Minamoto (Genji) and Taira (Heike) clans against each other for dominance over Japan. After years of conflict, the Taira had been driven westward and took to the sea, making a final stand in the Kanmon Straits near Dan-no-ura with the young Emperor Antoku under their protection.
On April 25, 1185, the Minamoto fleet under Minamoto no Yoshitsune engaged the Taira fleet at Dan-no-ura in the Kanmon Straits. The morning rip tide initially favored the Taira, but when it reversed in the afternoon, the Minamoto pressed their advantage and decisively defeated the Taira. Emperor Antoku and numerous Taira nobles perished in the battle.
The Taira clan's destruction at Dan-no-ura concluded the Genpei War and left the Minamoto as the dominant power in Japan. This outcome paved the way for Minamoto no Yoritomo to establish the Kamakura shogunate, inaugurating an era of warrior-class governance that would define Japanese political structure for centuries.
