===Papist Invaders versus Orthodox Christian Natives===
Before he set out from Normandy, William had had a difficult time in getting his own Norman barons to follow him in his quest to gain the English crown. Most considered it suicide, if only because of the difficulty in making the crossing over the English Channel in the relatively primitive boats that they used. Thus, William had a problem in terms of gaining military assistance in his campaign. The solution to that problem was presented by one of his advisers, Lanfranc,
the man who after the Conquest became Archbishop of Canterbury.
Lanfranc's solution came in the form of casting the invasion as a crusade to bring the English church into submission to the [[papacy]]. David Howarth, in his ''1066 The Year of the Conquest'', explains:
:The invasion should not be seen as a merely secular conquest; its highest aim should be, or appear to be, the reformation of the English church. It should become a crusade, a holy war to bring back an errant church to Rome. Lanfranc himself, or the Norman church as a body, was willing to bring accusations against the church of England (p. 100).
