This is a story about the man who saved Christendom.
So I was playing a Charlemagne playthrough. Was playing as Charlemagne's grandson, the third Holy Roman Emperor, Emperor Karl II, when I decided that since things were going well I would attack the Ummayads.
Unfortunately due to them being on good relations with all the Muslims in the world, I ended up fighting a few more people than I thought I was going to.
So just to clarify, out of 987 Muslim vassals and rulers in the world, I was at war with 907. There were only 80 Muslim landholders in the world, that were not at war with me.
I decided I would press forth and try and defeat the Umayyads before the rest of Islam got to me.
I was happily trouncing the 19,000 strong Hispanic armies with my 17,000 strong, loyal, Christian army trying to win the war before this guy arrived.
Caliph Mahdi 'the Great', Conqueror of Africa, Subjugator of Persia, and Bane of Byzantium, at the head of his 35,000 man armies.
I carried on fighting the Umayyads and smaller allies in Aragon, defeating about 20k of troops whilst losing about 5k myself. Had a good 55% warscore.
Then it happened...
The Crown Prince of the Abbasid's, heir to all of Islam from Tunsia to Kashmir began his invasion of Hungary.
Well his Highness' armies 'brutally' tore through my unguarded provinces, with no one stepping in his way.
Then after six months of strolling around hungary his armies pulled back to his own lands and the Abbasid's sent no more troops.
So I continued my battle with the Umayyad armies when I realised that the real threat had only just appeared. The Great Caliph himself was sailing straight towards my empire, ready to land in the Bay of Biscay and surround my troops in spain.
So the Caliph had landed with his 'army' but fortunately a Navarrese noble rode forth to do battle with the Great Caliph.
And the brave count defeated Mahdi the Great, ruler of the most powerful Muslim state since the Umayyad Caliphate at it's greatest extent.
Mahdi the Great retreated through Spain and never returned, leading to the success of Karl II, Emperor of the Romans in Liberating Aragon.
And that is the story of how an Amateur Plotter defeated the forces of Islam. All hail Saint Frances of Bearn, savior of Christendom!
