Even in the early period, despite facing a supreme Byzantine Empire, they have a fine selection of cavalry which are useful for classic Turkish warfare. It would also be foolish to believe that the Fatimid dynasty in Egypt will be content to simply overlook the fertile banks of the Nile - They are just as well placed to seize control of all of the Holy Lands. The Turks (faction colour light green) are a Muslim faction representing the Seljuk and Ottoman Turks. To expect Byzantium to underestimate Turkish forces after the slaughter of Manzikert would be folly, and it can be taken as given that they will attempt to regain control of Anatolia.
In the foreseeable future, arrogance and complacency are likely to be the biggest threats to the mighty Seljuk Empire. Considering they have relied upon their natural skill at mounted combat and guerrilla warfare for centuries, the Turks have already shown incredible talent at governing a vast empire from a single throne. Traditionally a nomadic people, they have at last adopted a system of centralised rule to form the Seljuk Empire. Settling down has been the Turks' secret to asserting their dominion.
Having seized control of the Abbasid Caliphate from the Buyids, and utterly crushed the Byzantines at Manzikert, the Turks have restored unity to the eastern Islamic region, making them arguably the greatest power Arabia or Persia has seen for centuries. The Turks may very much be relative newcomers to both Anatolia and the Holy Lands, but the impact that they have had upon these realms since they migrated from the steppes east of the Caspian has been profound enough to shake the pillars of the oldest and mightiest neighbouring dynasties.
