Benedict was born at Nursia (Norcia) in Umbria, Italy, around 480 AD. He was sent to Rome for his studies, but was repelled by the dissolute life of most of the populace, and withdrew to a solitary life at Subiaco. A group of monks asked him to be their abbot, but some of them found his rule too strict, and he returned alone to Subiaco. Again, other monks called him to be their abbot, and he agreed, founding twelve communities over an interval of some years. His chief founding was Monte Cassino, an abbey which stands to this day as the mother house of the world-wide Benedictine order.

The effect of the monastic movement, both of the Benedictine order and of similar orders that grew out of it, has been enormous. We owe the preservation of the Holy Scriptures and other ancient writings in large measure to the patience and diligence of monastic scribes. In purely secular terms, their contribution was considerable. In Benedict's time, the chief source of power was muscle, whether human or animal. Ancient scholars apparently did not worry about labor-saving devices. The labor could always be done by oxen or slaves. But monks were both scholars and workers. A monk, after spending a few hours doing some laborious task by hand, was likely to think, "There must be a better way of doing this." The result was the systematic development of windmills and water wheels for grinding grain, sawing wood, pumping water, and so on. The rotation of crops (including legumes) and other agricultural advances were also originated or promoted by monastic farms. The monks, by their example, taught the dignity of labor and the importance of order and planning.
