Rennyo (, 1415–1499) was the 8th Monshu, or head-priest, of the Hongan-ji Temple of the Jōdo Shinshū sect of Buddhism, and descendant of founder Shinran. Jodo Shinshu Buddhists often referred to as the restorer of the sect ( in Japanese). He was also known as "Shinshō-in" (信証院), and posthumously "Etō Daishi" (慧灯大師). During the conflict of the Ōnin War and the subsequent warfare that spread throughout Japan, Rennyo was able to unite most of the disparate factions of the Jodo Shinshu sect under the Hongan-ji, reform existing liturgy and practices, and broaden support among different classes of society. Through Rennyo's efforts, Jodo Shinshu grew to become the largest, most influential Buddhist sect in Japan.
