Clara of Assisi quickly found followers. One of the first foundations beyond the Alps was the Cecilian Monastery in Pfullingen, established in 1252. As part of the work, the monastery archive, which consists of nearly 700 documents and numerous other records, was fully evaluated for the first time, allowing for a comprehensive representation of the intellectual, social, and economic history of the convent. The study thus makes a fundamental contribution to the largely pending research on the female branches of mendicant orders in Southwest Germany.
