Chronological evolution, geographic space and the characteristics of the protagonists of witch hunts in Navarre in the 16th and 17th centuries. Several judicial and extrajudicial instances took part in the persecution: The Royal Courts, the Inquisition, the diocesan tribunal, local justices or the very neighbours of those accused. They all followed diverse procedures, they all collaborate with each other and confronted each other. Their attitudes were also diverse: from the belief in the existence of a sect of witches, to scepticism and pious rationalism.
