the church. The Norman kings had traditionally exercised a great deal of power and autonomy over the church within their territories. From the 1040s onwards, however, successive popes had put forward a reforming message that emphasised the importance of the church being "governed more coherently and more hierarchically from the centre" and established "its own sphere of authority and jurisdiction, separate from and independent of that of the lay ruler", in the words of historian Richard Huscroft. When news began to spread of Henry I's death, many of the potential claimants to the throne were not well placed to respond. Geoffrey and Matilda were in Anjou, rather awkwardly supporting the rebels in their campaign against the royal army, which included a number of Matilda's supporters such as Robert of Gloucester. Many of these barons had taken an oath to stay in Normandy until the late King was properly buried, which prevented them from returning to England. Stephen's brother Theobald was further south still, in Blois. Stephen, however, was in Boulogne, and when news reached him of Henry's death he left for England, accompanied by his military household. Robert of Gloucester had garrisoned the ports of Dover and Canterbury and some accounts suggest that they refused Stephen access when he first arrived. Nonetheless, Stephen probably reached his own estate on the edge of London by 8 December and over the next week he began to seize power in England. The crowds in London traditionally claimed a right to elect the King, and they proclaimed Stephen the new monarch, believing that he would grant the city new rights and privileges in return. Henry of Blois delivered the support of the church to Stephen: Stephen was able to advance to Winchester, where Roger, Bishop of Salisbury and Lord Chancellor, instructed the royal treasury to be handed over to Stephen. On 15 December, Henry delivered an agreement under which Stephen would grant extensive freedoms and liberties to the church, in exchange for the Archbishop of Canterbury and the Papal Legate supporting his succession to the throne. There was the slight problem of the religious oath that Stephen had taken to support the Empress Matilda, but Henry convincingly argued that the late king had been wrong to insist that his court take the oath. Furthermore, the late king had only insisted on that oath to protect the stability of the kingdom, and in light of
