At this point, I pretty much HAVE to ask.
Is there any mod anywhere that actually makes the Umayyads and Abbassids break up? I've seen it happen a grand total of twice in all my games without me intervening and fucking them over via mass command use.
In my Miroslav empire game the Umayyad and Abbasid were overthrown by Mansurid and Koserid dynasties very early on, with the Umayyad driven to total extinction and the Abbasid only regaining control over the Caliphate after 3 centuries of no rule.
In my eternal Miroslav Serbia game it's not as severe of an implosion in either, but the Umayyad were rising in power up until they got crusaded out of Aquitaine and the Abbasid blob just got absolutely wrecked.
The Byzantine blob and Abbasid blob kept fighting each other, constantly trying to get the one up on one another. For the most part the Byzantine Empire emerged victorious in these wars until the Byzantine Empire surpassed the Abbasid Empire, only held in check by the scheming of the Miroslav family. After the Abbasid's failures to destroy the Byzantines, a failed invasion of India and a reign of a limp Caliph, two great revolts split the Abbasid blob apart during a miaphysite and a zoroastrian revolt and a war with the Byzantine Empire.
The Abbasid Empire was of such a weak state that it lost to the Byzantines again and by the time the revolts and Miaphysites were crushed the Zoroastrians succeeded in making away with south-eastern Persia, led by a hunchbacked strategist. Aforementioned hunchbacked general was in turn succeeded by a genius who managed to conquer the Zunists of Afghanistan after two wars; now the Abbasid have to contend with a Zoroastrian state in the East, the Umayyad in the West and close to home a threat greater even than the Byzantines.
SHIA
This kid is both fair and clever. He appeared one day whilst the Shia in Jerusalem were getting pissy and started a full scale insurrection.
I looked back on the middle east to find that the Abbasid blob was not what it used to be:
Jerusalem fell. Then Syria, but I was not too concerned by that, the Abbasid blob couldn't touch Serbia after all.
Then they wrecked the Byzantine Empire as well. They just took on the two greatest powers on the planet like it was nothing. I love the bastards! In general, Muslim nations are impervious to harm as long as they win, and always win. Stop being victorious and they fall apart.
I also like how history repeats itself. The first Muslim conquests were enabled by the Byzantines and Persians exhausting each other with their power struggles until they both lost horrendously. The Shia conquests were enabled by the Byzantines and Abbasid exhausting each other with their power struggles until they both lost horrendously. With any luck the Shia or a Sunni follow up will finish the Byzantines off all the way past Constantinople and Serbia will be able to begin removing kebab and reclaiming the Empire under Miroslav. Whatever the case, the Basilius will no longer be able to invade the Serb. Ohrid is not forgotten, one day it will belong to Serbia again.
