Minamoto clan

Minamoto (源; Japanese pronunciation: [mʲi.na.mo.to]) was a noble surname bestowed by the Emperors of Japan upon members of the imperial family who were excluded from the line of succession and demoted into the ranks of the nobility since 814. Several noble lines were bestowed the surname, the most notable of which was the Seiwa Genji, whose descendants established the Kamakura and Ashikaga shogunates following the Heian era. The Minamoto was one of the four great clans that dominated Japanese politics during the Heian period in Japanese history—the other three were the Fujiwara, the Taira, and the Tachibana.

In the late Heian period, Minamoto rivalry with the Taira culminated in the Genpei War (1180–1185 AD). The Minamoto emerged victorious and established Japan's first shogunate in Kamakura under Minamoto no Yoritomo, who appointed himself as shōgun in 1192, ushering in the Kamakura period (1192–1333 AD) of Japanese history. The name "Genpei" comes from alternate readings of the kanji "Minamoto" (源 Gen) and "Taira" (平 Hei).

The Kamakura Shogunate was overthrown by Emperor Go-Daigo in the Kenmu Restoration of 1333. Three years later the Kenmu government would then itself be overthrown by the Ashikaga clan, descendants of the Seiwa Genji who established the Ashikaga shogunate (1333 to 1573).

The Minamoto clan is also called the Genji (源氏; [ɡeɲ.dʑi], lit. 'Minamoto clan'), or less frequently, the Genke (源家; "House of Minamoto"), using the on'yomi readings of gen (源) for "Minamoto", while shi or ji (氏) means "clan", and ke (家) is used as a suffix for "extended family".
