A large number of scholars, among whom was Saint Eugendus, placed themselves under the direction of the two holy brothers who founded several monasteries including Romainmôtier (Romanum monasterium) in the canton of Vaud in Switzerland.
[3] Only a rhymed chronicle from the 13th century and the writings of Commissioner Aymonnet Pollen (1519) describe the founding of Romainmôtier Priory.
In 649 Saint Wandregisel, the future abbot of Fontenelle Abbey, visited Romainmôtier and found a thriving and diverse monastic life.
Pope Stephen II visited the monastery in 753 while traveling for a meeting with Pepin the Short and according to tradition consecrated the churches of Saints Peter and Paul.
At some point between 966 and 990, King Conrad of Burgundy finally renounced all his rights and gave the monastery to Abbot Maiolus of Cluny.
In the 10th and 11th centuries, the monastery was fighting against aristocratic families of the region (Grandson, Salins) who were trying to expand their estates at the expense of the priory.
However, the pariage of 1181, in which Beatrix of Burgundy, the wife of Frederick Barbarossa, and the priory divided their rights, appears not to have been followed.
[3] The property of the priory included the territory around the monastery, which was known as La Poté (derived from the Latin word potestas), or Terre de Romainmôtier.
In the 12th century, small priories were established in Bursins, Mollens, Vufflens-la-Ville, Vallorbe and Lay-Damvautier to manage the far-flung holdings of Romainmôtier.
The priories of Bevaix and Corcelles were affiliated with Romainmôtier in the 12th century, but until its secularization during the Protestant Reformation, they retained a certain independence.
[3] In the 11th century, the inhabitants of the Poté were still serfs, but in 1266 they were awarded a special legal status: they possessed personal freedom and were allowed to dispose freely of their goods, but were obliged to be faithful to the prior.
Those of the familia class were not subject to compulsory service or collective work, but were required to pay the heriot or death tax.
Some monks settled in Vaux-et-Chantegrue and created a simple countryside priory, which was abolished during the French Revolution.
