The Edumean sect of Messianic Sadducees began in Tachkastan with a Sadducee called Mahmet the Ishmaelite who adopted certain Manichean ideas about Rebbe Yehoshua Minzaret and the Mishnah which Rebbe Yehoshua Minzaret promoted.
Background
Mahmet the Ishmaelite was originally a Sadducee warlord who rose to prominence in Tachkastan and brutally suppressed the followers of Rebbe Yehoshua Minzaret.
