spain, italy, the balkans and hungary
The European Catholic side:
France, Germany, Poland, Russia, Scandinavia and the UK.

in africa/middle east we will have the islamic side the egypt, anatolia, iran (or better persia) and arabia VS ethiopia and its friends.

the Maghreb region vs everyone
spain vs everybody (with maybe the exception of italy the maghreb region ( if they have the same "religion") and the country in constantinople/balkas/hungary)
Italy vs the northern Christian kingdoms and naval battles for control of the Mediterranean.
Balkas+Hungary vs Christians in the north and other Muslims in the south.
Egypt-Syria vs Anatolia and Iran. With arabia in the middle.
