HAHAHAHAHA
THE SHIA CALIPHATE JUST GOT WRECKED SO HARD, THE SERBIANS ARE NOW THE KINGS OF THE KINGDOM OF HEAVEN! JERUSALEM IS MINE! HAHAHAHAA!
To put a long story short (rest assured I will type up the long story later), seeing as how all the pagans, christians and muslims were unlocking their great holy wars the Shia felt a little left out. So they got ready for jihad, founded the Bektashi order and declared jihad on the Byzantine Empire's Kingdom of Armenia. Considering how this would throw the first gains the Byzantine Empire's made in centuries back down the drain whilst also threatening the Miroslav family's eastern border, Emperor Slavko Miroslav was rather worried. He joined the war to support Emperor Krsto in his endeavours. Soon enough everyone and their mum was fighting in the mountains of Armenia and Anatolia, with Shia rushing to support their Caliph from Venice to Bagdhad, and on the Christian side I even saw a tribal army from a Turkic Catholic Chief all the way from Perm. The Shia forces destroyed the Byzantine forces (the Shia had over 60,000 soldiers!), but luckily the holy orders and attrition (NEVER START A WAR IN ARMENIA) whittled down that number fairly quickly, leading to horrible, horrible stagnation. Emperor Slavko himself lost 13,000 Serbian forces - they arrived in Armenia to recapture all the cities Emperor Krsto lost, only to find that the way back was full of Actual Cannibals Shia Labeoufs. RIP 13,000 Serbs.
Now, I had fought a 20 year Jihad in Armenia in another game. It was awful. And Emperor Slavko was getting too old for this shit, no way was he going to live to see 20 years of Jihad in Armenia through. Armenia is the worst place for a Jihad, everyone dies from attrition. So I did what helped break the deadlock in the 20 year jihad and created a new army and just marched straight for the enemy's capital to completely fuck up their supply chains.
So I do that. The Shia forces take the long way around my Serbs because they fear the kebab removers, allowing the Gusars to press deeper from the Byzantine county of Antioch into Shia territory. At around 7 or 8 years in, when millions have been killed, the world is tits up shit but the Serbian forces are alive and kicking. The Ferzadid Zoroastrians are invading the Amrids, the Solominid Abyssinians have killed the Nubian branch and consolidated the Abyssinian Kingdom, the Malian Kingdom is waging war with the Azzizid Andalusians and Aquitaine is being invaded by Muslims yet again while the Bahirid Empire blob is weeping the tears of a thousand Yazidi heretic revolts. Somewhere in the background the Suomensko pagans can be heard sacrificing Norsemen, and the Empire of Bengal crushes its enemies beneath the feet of its war elephants. Seeing as the world is in such a peaceful state, the Pope calls a crusade on Jerusalem, just to make sure that EVERYONE gets SKULLS FOR THE SKULL POPE.
The Shia Jihad for Armenia ends as the Byzantines send in all they've been building up for the last 6 years and the Serbs clear county after county, getting gold and prisoners along the way.
Emperor Slavko 'The Bold' Miroslav of Serbia asks the Pope if he could kindly join the V Crusade. Pope says yes. With 12,000 Serbian troops parked in Jerusalem already, the Serbs immediately attacked Beirut. Caliph Burnahaddin II 'The Great' Barrani of Jerusalem suddenly found Teutonic Knights invading Anatolia, Serbian forces already in Jerusalem and the whole damn Crusader rape train on its way. And unlike his Jihad, this time only one Shia count felt like defending Burnahaddin after he got millions of Shia killed for nothing. And I shit you not, there were Crusaders showing up from as far away as Scotland and Ireland. UIB BROS YOU FAIL ME NOT!
Needless to say, resistance was futile. There was only Miroslav. Serbian foreign policy may have to change from interventionist to active kebab removerist.
