Battle of Yarmouk

The Battle of Yarmouk was a major battle between the Muslim Arab forces of the Rashidun Caliphate and the armies of the Eastern Roman Empire. The battle consisted of a series of engagements that lasted for six days in August 636, near the Yarmouk River, along what today are the borders of Syria-Jordan and Syria-Israel, east of the Sea of Galilee. The result of the battle was a complete Muslim victory which ended Byzantine rule in Syria. The Battle of Yarmouk is regarded as one of the most decisive battles in military history,^[6] and it marked the first great wave of Islamic conquests after the death of prophet Muhammad, heralding the rapid advance of Islam into the then Christian Levant.
