Muslim conquest of Syria

The Rashidun Caliphate conquered Byzantine Syria between 634–638 CE as part of the Arab–Byzantine wars and the wider Muslim conquests.

Clashes between the Muslims and the Byzantines on the southern Levantine borders of the Byzantine Empire had occurred previously during the lifetime of Muhammad, with the Battle of Mu'tah in 629 CE. However, the actual conquest did not begin until 634, two years after Muhammad's death. It was led by the first two Rashidun caliphs who succeeded Muhammad: Abu Bakr and Umar. During this time, Khalid ibn al-Walid was the most important commander of the Rashidun army. In the aftermath of the conquest, Syria was brought under Arab Muslim rule and developed into the provincial region of Bilad al-Sham.
