Monks of Russ advocated a devotional monastic life. The monastic life originated in Egypt, and the monastic system became more perfect after it was introduced into Byzantium. The Russ's monastic system was deeply influenced by Byzantine factors. Grand Duke Yaroslav established the first monastery of Russ, accordingly produced a more perfect monastic system. There were two kinds of monasticism: hermitage and collective residence. Owing to the religious support by the princes and nobles, the monastery had the following features: being located in or close to the city, increasing economic strength, and playing an important role in politics. Relying on the development of monasteries, monks gradually developed and expanded their power, thus formed an alliance of religious and secular feudalists.
