130 The Norman Conquest remain. But it became clear to him and to Lanfranc that a general overhauling of the church was needed. Probably they did not at first realise how serious were the differences between the English church and that which they had always known; its ignorance and its mar- ried clergy must have surprised them as much as its archaic customs and its isolation. About Easter of 1070 a council met, at which three papal legates were present. The removal of Stigand, archbishop of Canterbury, whose irregular supersession of Robert of JumiŁges had helped win the pope to the support of William, was its first work. From this beginning, the process of displacement and filling of vacancies went on rapidly until, at the end of the year, only two or three English bishops were left. While the reign of William covered the period of the great conflict between Gregory VII. and the Emperor Henry IV. over the manner of investing prelates, Wil- liam did not abate in the least his part in the ceremony.1 With this wholesale creation of Norman bishops and the consecration of Lanfranc as archbishop of Canterbury in August of the same year, the transformation of the English church was well under way. In the early years of William's reign there was some- what the same merging of church synod in state council that prevailed during much of the Anglo-Saxon period. But such a confusion was contrary to the continental distinction between church and state, and one marked change is to be seen from the start: whereas the assem- bly might be summoned by the king, and barons as well as clergy attend, the final decision in church matters lay with the clergy. The church made its own laws. In the course of time this real legislative independence TThe compromise on the ceremony reached between Henry I. and Anselm in 1106 did not mean that the king gave up at all his power really to determine who the bishops should be. In this connection should be remembered the double position of bishops who were now not only great prelates but also vassals of the king holding baronies from him. Many of the abbots were his feudal tenants-in-chief also, but the king did not so generally interfere in their choice. They were usually chosen canonically by the monks.
