William the duke of Normandy: 1048 to 1060

"William the (antichrist) Bastard." That is the best you can hope for if you succeed. Odo is probably already an incurable megalomaniac; that you would promote his insane ambition (which otherwise would not have surfaced until he was growing old and senile), only proves that in your hands no churchly honor or office is safe or sacred.

But in fact, there is no chance of this ever happening, so your time and efforts are utterly wasted on nothing. When it comes time to press your claim to the English throne, and you need the backing of the church, your brother will not be in any position to absolve you and reverse your excommunication: and the pope (Alexander by name) will not give his approval for your campaign. You will be fortunate if you are not the actual focus of a crusade against Normandy.
