The Strigolniki (singular Strigólnik– Стригольник in Russian) were followers of the first Russian heretical sect of the middle of the 14th and first half of the 15th century, established in Pskov and later in Novgorod and Tver. However, the teachings of the Strigolniki lived on. They spread widely in Novgorod, in Pskov, and also in Tver, where bishops Feodor Dobry and Yevfimiy Vislen came forward with support for the movement. In the early 15th century Photius, Metropolitan of Kiev and all Russia, denounced the Strigolniki teachings.
