The Heresy of the Judaizers (Russian: ересь жидовствующих, romanized: yeres zhidovstvuyushchikh)[1][2] was a religious movement that emerged in Novgorod and later Moscow in the second half of the 15th century which marked the beginning of a new era of schism in Russia.[3] Initially popular among high-ranking statesmen and even the royal court, the movement was persecuted by the hegumen Joseph Volotsky and the archbishop Gennady of Novgorod. Several councils of the Russian Orthodox Church later condemned the Judaizers as heretics.[4]
Some scholars see them as a Russian variant of the pre-Reformation era.[5] Any filiation with the strigolniki, who appeared in the 14th century, remains conjectural, but highlights the religious situation in Novgorod at the time.[6]
