So, I am playing as an African Catholic King. The only real challenge so far that I have had is the Umayyad Sultanate which is giving me quite the run for my money. I have been trying to make some allies but most of Europe has shattered. The only major players left other me and the Umayyad Sultanate in Europe are Lombardy and the Byzantine Empire - both of which are suffering from revolt after revolt. It is only 823. The Umayyad have already got a fair bit of land from what was once Francia. It would appear that I will be the only power able to take them down, but I can't do it alone. I am trying to conquer as much land as I can and saving as much money as I can in order to hire as many mercenaries as I can. Hopefully, I can beat the Sultanate up enough to make them shatter. Any other hints or suggestions?
