Chinzei in the context of "Jōdo-shū"

Ikkō-shū (一向宗) or "single-minded school" is usually viewed as a small, militant offshoot from Jōdo Shinshū Buddhism, though the name has a complex history.

Originally, Ikkō-shū was an "obscure band of Pure Land proponents" founded by Ikkō Shunjō in the fifteenth century. He was a disciple of Ryōchū of the Chinzei branch of Jōdo-shū Buddhism and similar to Ippen's Ji-shū. However, when the religious and military-political establishment began to crack down on the Nembutsu, little distinction was made between the various factions. Most of Ikkō Shunjo's followers therefore defected to the more powerful Jōdo Shinshū and the name Ikkō-shū ultimately became synonymous with Jōdo Shinshū.

Benchō (弁長; June 20, 1162 – March 16, 1238), was a Japanese Buddhist monk and religious leader who was one of the main disciples of the Pure Land founder Hōnen. Also known as Shōkō Shōnin (聖光上人) or Shōkōbō (聖光房), Benchō, is the second patriarch of the Chinzei branch of Jōdo-shū, one of the major schools of Japanese Buddhism. Benchō's missionary efforts in Kyushu, especially Chikushi, and his founding of Zendō-ji temple, led to the establishment of the Chinzei-ha (鎮西流) sect.
