American-Cassinese Benedictine Congregation

The American-Cassinese Congregation is a Catholic association of Benedictine monasteries founded in 1855. The monasteries of the congregation follow the monastic way of life as outlined by St. Benedict of Nursia in his early 6th century Rule of Saint Benedict. The congregation is one of 19 congregations in the Benedictine Confederation and includes 25 monasteries: 19 autonomous abbeys and 6 dependent priories, located across 15 states and Puerto Rico, as well as Brazil, Canada, Colombia, Mexico, and Taiwan.

History
In the eighteenth and early nineteenth centuries there was a general secularization and suppression of monasteries throughout Europe: "by 1810 fewer than thirty of the estimated 1500 European Benedictine monasteries that existed in the previous century remained." Slowly, there arose a Benedictine revival that saw old monasteries re-founded, new monasteries founded, and a missionary impulse that began to spread monasticism across the world. Autonomous monasteries began to join together in collaborative efforts that would see the creation of "congregations" such as the French Solesmes Congregation in 1837, the Beuronese Congregation in 1868, the Subiaco Congregation in 1872, and the Swiss-American Congregation in 1881. It was in the midst of this revival that Abbot Boniface Wimmer, founder of Saint Vincent Archabbey in Latrobe, Pennsylvania, created the American-Cassinese congregation. Pope Pius IX erected the congregation with the decree Inter ceteras on 24 August 1855, placing the congregation under the patronage of the Holy Guardian Angels.

The American-Cassinese Congregation was the first Benedictine congregation to be established in North America, and after only a quarter-century of existence, had become the largest Benedictine congregation in the world.
