Reader's Guide
The Genpei War marked a pivotal transition in Japanese history, ending the Taira clan's dominance at the imperial capital and ushering in the Kamakura shogunate, Japan's first military government. Kyoto remained the de jure capital and seat of national ceremony and ritual. The war's name derives from alternate readings of the kanji for Minamoto (Gen) and Taira (Hei/pei), though some argue the term 'Genpei' is not appropriate for this conflict. The war also saw the use of deceptive tactics, such as the Emperor's false truce offer to regain the Imperial regalia, and the defection of a Shikoku warrior at Dan-no-ura, which proved decisive.
