平氏
The Taira clan was one of the four great clans which dominated Japanese politics during the Heian period (794–1185). As a result of the near-total destruction of their rival clan, the Minamoto, in the Heiji Rebellion of 1160, Taira no Kiyomori, head of the clan, initiated the Genpei War at the height of his power. The end of the war, however, brought destruction to the Taira clan.
