After the Muscovite conquest in 1470–1478, the office fell somewhat into decline. The first three Muscovite archbishops were removed in disgrace, although the second one, Gennady (1484–1504), successfully suppressed the Judaizer Heresy (called the "Zhidovstvuyuschiye" in Russian) and compiled the first complete corpus of the Bible in Slavonic (the Gennady Bible, now housed in the State Historical Museum). His successor, Serapion was removed from office after only three years and the see sat vacant for seventeen years (1509–1526).
