Ikkō-shu (一向宗, ikkōshū) is usually viewed as a small, militant, offshoot from Jodo Shinshu Buddhism though the name has a complex history. Originally Ikkō-shu was a small antinomian sect founded by Ikkō Shunjo (a disciple of Ryochu of the Chinzei branch of Jodo-shu Buddhism) and similar to Ippen's Ji-shu. However when the religious and military-political establishment began to crack down on the Amida-pietist movement little distinction was made between the various factions. Most of Ikkō Shunjo's followers therefore defected to the more powerful Jodo Shin-shu and the name Ikkō-shu ultimately became synonymous with Jodo Shinshu (Dobbins 2002).
