Middle East - What Is the History of Islam?

The Middle East has basically two major zones, three if you want to stretch it. The Arabian Peninsula which was never taken so seriously becomes very very powerful. Iran culturally has its own culture of Persia and therefore Iranian Islam is Moshyad or Shia. Sunni follows a more tribal egalitarian way of thinking and doesn't believe in the bloodline but Persians because they have a dynastic royal heritage prefer the dynastic bloodline.
