The Benedictine Confederation

The Benedictine Confederation is the body into which the Benedictine Congregations and monasteries of the Catholic Church are gathered. It was established in 1893 by Pope Leo XIII with his brief Summum Semper.


The Congregations of monks are the ordinary members of the Benedictine Confederation. A few single monasteries that for particular reasons have remained outside a Congregation have been admitted as extraordinary members.

Monasteries and Institutes of Benedictine Women are associated with the Benedictine Confederation and constitute the Communio Internationalis Benedictinarum (CIB).
