odin --- you do not need to go back so far. Recently the original speech regarding the War on Terror used the word 'crusade' in the perceived context of a just war. This war was also portrayed using the religious and subjective terms of 'Good' and 'Evil'.

I do not believe we are demons, we are just humans.

PS> The Norman Conquest was not a crusade due to religion at all. William, at the time the Duke of Normandy, felt he had a greater claim to the throne because Harold had promised it to him under duress. William's problem was further complicated by the fact that he was illegitimate, and his claim was week, relying on a promise made by Edward the Confessor. He invaded England anyway and won. He turned out to be a really good administrator, but he was never 'the Great' in Britain!
