Start with the geography, because it explains the name. Two shrines stand along the Kamo River, and together they are called the Kamo Shrines. The one upstream is Kamigamo; the one downstream — lower, shimo — is this one, Shimogamo. Both were the clan deities of the Kamo family, and because this shrine honors the clan's ancestral deity, it is formally known as Kamo Mioya Jinja, the shrine of the revered ancestor. That ancestry gave Shimogamo enormous standing at the birth of the capital. When Heian-kyo was laid out in the late eighth century, prayers were reportedly offered here first for the new city's success. Before long this was the leading shrine of Yamashiro Province, venerated as a guardian of the capital and of the imperial family, alongside the deity of Kamigamo upstream. The court bound itself to the shrine through institutions — ritual renewal, and the Saio, an imperial princess who served here as a sacred figure. The shrine appears in court literature, in The Tale of Genji and The Pillow Book, and after the Meiji era it was ranked at the very top among the nation's shrines as a great shrine with government support. There is another story worth holding lightly. One account says the court deliberately divided a single, powerful Kamo shrine into two, partly to reduce the clan's strength. That is a widely repeated explanation rather than a proven fact — a reminder that politics and worship have long been entangled at this spot.
