What if the Battle of Qadisiyyah Had a Different Result

The battle of Qadisiyyah was fought in 636 CE from November 1-4. The battle is not known well in Western history but it had major implications for the West and much of the globe. This was a battle where the Arab armies, newly converted to Islam, were able to defeat the Sasanid Persian Empire. The result was the conquest of what is now Iraq and eventually Persia, allowing the new Islamic Empire to emerge in the Middle East and, eventually, expand to other areas.
