Have anyone ever seen the Almohads in CK3 accomplish anything at all? Me neither. they always spawn in my games around the year 1150 but they never do anything. They spawn and just a few years later they end up being eaten by someone else.
When Paradox announce the Muslim faiths "rework" in the Dev Diary #98 i immediately thought of the Umayyad Caliphate and the Almohad Caliphate but while the Ummayad at least got some new things the Almohads end up having nothing.
In the reality the Almohads where a menace not just for Christianity but also for other Muslims in the Iberian Peninsula and the North of Africa. Maybe you can ad them a few more Special Soldiers when they spawn or make the Special Soldiers inheritable with the Caliph title so they can actually be a Menace and slowly start to take over the North of Africa or maybe give them a new decision or event that gives the player a reason to play as the Almohads or at least take them in consideration while playing in the Iberian Peninsula and the North of Africa.
Also, in the game they appear around the 1150 even when in the reality the Almohads expansion inside Africa starts between the 1117 and the 1121 and they arrived into the peninsula in the year 1145.
(In the attached image they spawned in the year 1142 year and managed to get 2 recently independent counties but just a few years later they lost them against the Magreb Kingdom that has been eating the Almohads one county at a time for the last 40 years with the Almohads not being able to do anything to stop them)
