It marks the site of Cereatae, the birthplace of
Caius Marius, afterwards known, as inscriptions attest, as Cereatae Marianae, having been separated perhaps by the triumvirs from the territory of Arpinum. In the early
Imperial times it was an independent community.
Benedictine A
chronicle of the abbey from the 13th century dates its founding to the 9th century as a
Benedictine monastery with the same name. Initially a small community with a simple church dedicated to Saints John and Paul, the buildings were expanded in the mid-11th century by its then-Abbot Giovanni. That it became a sphere of influence for the region at that time is shown by the large number of donations it was receiving and its acquisition of many chapels in the area whose revenues contributed to the maintenance of the abbey.
Cistercian The 12th century, however, saw a period of long decline for the abbey. Due to the severe financial crises which arose in the shift to a capital-based economy, the region underwent great instability. In the religious realm, the Church was suffering from the contending rule of
Antipope Anacletus II and
Pope Innocent II. During this period, one of the major religious figures of the day, St
Bernard of Clairvaux, promoted the
Cistercian reforms of monasticism as the best way to ensure fidelity of life and obedience to the Church. He himself arranged the incorporation of Casamari in the new order, officially listing it in the Cistercian directory as the 29th foundation of
Citeaux. In 1417 the abbey suffered major damage due to an assault by the army of Queen
Joanna II of Naples, allied with the
papacy, on the forces of
Braccio da Montone which had occupied the monastic complex. The entire western wing of the abbey was destroyed in the battle. In 1717, the commendatory abbot at that time,
Annibale Albani, made an attempt to reform and reinvigorate the community by introducing the
Trappist reform, bringing several monks for this purpose from the Trappist monastery of Buonsollazzo in
Tuscany, part of the Italian
Congregation of St. Bernard. Soon, though, the abbey, along with most other religious communities, was
suppressed by a decree of
Napoleon in 1811. ==References==
