Who created a set of rules for monks in the Byzantine Empire?

The set of rules for monks in the Byzantine Empire was primarily established by Saint Basil the Great in the 4th century. His monastic rule, known as the "Rule of Saint Basil," emphasized communal living, prayer, and the practice of virtue. This framework influenced the development of monasticism in the Eastern Orthodox Church and shaped the lifestyle of monks throughout the Byzantine Empire. Saint Basil's teachings continue to be significant in Orthodox monastic practice today.
