Explain the historical circumstances that led to the Crusades Raymond d’Aguiliers

Raymond of Aguilers was a participant in and chronicler of the First Crusade (1096–1099). During the campaign he became the chaplain of Count Raymond IV of Toulouse, the leader of the Provençal army of crusaders. His chronicle, entitled Historia Francorum qui ceperunt Iherusalem, which he co-wrote with Pons of Balazun, ends with the events immediately following the capture of Jerusalem in 1099.

Everything we know about Raymond is derived from the Historia, the idea for which he credits to Pons. He must have been the main author and finisher, however, since Pons died before the capture of Jerusalem. The Historia was probably written as the crusade progressed and the preface added later. It was completed before the death of Count Raymond in 1105.
