Shinran (1173–1263) lived during the late Heian to early Kamakura period (1185–1333), a time of turmoil for Japan when the emperor was stripped of political power by the "shōguns". Shinran's family had a high rank at the Imperial court in Kyoto, but given the times, many aristocratic families were sending sons off to be Buddhist monks instead of having them participate in the Imperial government. When Shinran was nine (1181), he was sent by his uncle to Mount Hiei, where he was ordained as a śrāmaṇera in the Tendai sect. Over time, Shinran became disillusioned with how Buddhism was practiced, foreseeing a decline in the potency and practicality of the teachings espoused.
