The Battle of the Yarmuk was a major battle between the army of the Byzantine Empire and the Arab Muslim forces of the Rashidun Caliphate. The battle consisted of a series of engagements that lasted for six days in August 636, near the Yarmouk River, along what are now the borders of Syria–Jordan and Syria-Israel, southeast of the Sea of Galilee. The result of the battle was a crushing Muslim victory that ended Roman rule in Syria after about seven centuries. The Battle of the Yarmuk is regarded as one of the most decisive battles in military history, and it marked the first great wave of early Muslim conquests after the death of the Islamic prophet Muhammad, heralding the rapid advance of Islam into the then-Christian/Roman Levant.

The Rashidun Caliphate was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE. During its existence, the empire was the most powerful economic, cultural, and military force in West Asia and Northeast Africa.
