The foundation of the Terra Sancti Benedicti can be traced back to the large donation of land made in 744 to the monastery by the
Gisulf II of Benevento. The donation was probably of both a religious and political nature: thus an alliance between the Church and the
Duchy of Benevento was guaranteed to defend each other. In the following centuries, monasteries, churches and castles with annexed possessions were gradually offered to the monastery, even overseas, through concessions and donations made by nobles, emperors and popes, reaching eighty thousand hectares. The history of the territories linked to the Benedictine Abbey can be divided into three main phases which correspond to three different approaches to the control of the territory: first the age of the
Manorialism, then that of the "
castrum" and finally that of the development of the "
universitas civium". Subsequently, the Abbey progressively loses its historical temporal power. After these phases of development, the loss of power by Montecassino and the fading of the territory it had controlled into larger organisms began with alternating events. An earthquake destroyed the Abbey in 1349 and, although it soon returned to its function, the event can be considered an important watershed. In the 14th century, the
Papal States tried to limit the abbey ecclesiastical jurisdiction placing a bishop at
San Germano, but the abbots managed to maintain many prerogatives thanks to
Pope Urban V. The official end of the feudal lordship came in 1806 with the abolition of feudal rights in the
Kingdom of Naples sanctioned by the so-called "laws of subversion of feudality". With the loss of temporal power, the jurisdiction of the abbey over the surrounding territory remained only ecclesiastical, as a territorial abbey: the abbots were equated in their functions with diocesan bishops, even if in most cases they were not awarded the episcopal character. ==References==
