10 Hryven Theodosius of the Caves

Theodosius of the Caves co-founded the Kyevo-Pecherska Lavra — the Monastery of the Caves — in the eleventh century alongside Anthony of the Caves, establishing what became the most influential monastic institution in Kievan Rus. Unlike Anthony, who preferred the solitary life of a hermit, Theodosius organized the community along the lines of the Studite rule from Constantinople, effectively importing Byzantine cenobitic monasticism into the Slavic world. The Lavra went on to train bishops, produce chroniclers including the probable author of the Primary Chronicle, and survive Mongol destruction in 1240 before re-emerging as a center of Orthodox ecclesiastical authority.
