Abbot Bernard of Tiron (c. 1046–1117) was one of the many Catholic Church people and religious leaders who had many followers at the turn of the 11th to 12th centuries, and his importance went beyond the local. Bernard’s settlement did not develop in the same way as other small hermit communities that disappeared or were gathered by the larger monastic congregations. Tiron will become the head of the association of the monasteries and Bernard as founder will be honored in the writings of his life and work. His success in Tiron was widely recognized and the monastic community he founded attracted attention after he died and, for some period of time, was recognized as one of the most important representatives of monastic life.
The present article is an attempt to show the activities of St. Bernard of Tyrone, a Benedictine reformer from the 11th and early 12th centuries, and the founder of the abbey in Tyrone, which stood out by returning to a stricter Benedictine way of life and had a network of monasteries. With his life and career as an abbot and hermit, he set an example and gathered people around him, and in that way influenced the transformation of the religious life of that time, primarily in France and England.
