Monasticism began when individuals left civilization in late Roman times to live alone in remote areas as ascetics closer to God. Saint Benedict formalized monastic life with rules for western monks, dividing each day between prayer, reading, manual labor and sleep. Monks lived simply, taking vows of poverty, obedience, and chastity while devoting their lives to prayer, work, and spreading Christianity. Their monasteries became centers of farming, education, invention, and beautiful architecture that helped preserve knowledge and shape medieval Europe.
