Saissac

The strong man of the Trencavel lands during the minority, an early convert to the Cathar faith who uses force for his co-believers.

His seizure of the abbey of Alet in 1197, with a dead abbot propped in the chair to preside over the election of a Cathar-friendly successor and the archbishop of Narbonne bought to confirm it, is the most notorious act of the regency.
