The Islamic conquests that took place during the first Hijri century changed the face of history and reshaped the world, as it transitioned from the Ancient Era to the Middle Ages.
They were unprecedented and followed centuries during which Arabs had hardly any global presence and were mired in endless civil wars and mass migrations.
But then, over just a few years, the Arabs were toppling the centuries-old Persian Empire and moving on to the Byzantine Empire, capturing its cities one by one until they reached the capital, Constantinople.
The rest of the world scrambled to come to terms with the rise of the Arabs, unexpected conquerors who became a new world power, taking over major cities and turning the Mediterranean into an Islamic region.
A bold move on two fronts
It all started when the first Muslim Caliph, Abu Bakr Al-Siddiq, made the bold decision to send two armies simultaneously to confront the two greatest empires of the time.
These wars that the wise leader waged proved to be among the greatest and most influential in the course of human history.
Ever since they were fought, numerous researchers, orientalists, and historians have pondered the mystery of how and why these sweeping conquests were devised and carried out.
As late Egyptian writer Abbas Mahmoud al-Aqqad wrote: “Over a short time span of seven years, the Arabs managed to invade and take over all the territories they could reach in the empires of Persia to the east and Byzantium to the north and west."
“The Persian Empire crumbled, while the emperors of Constantinople lost their control over Syria, Palestine, Egypt, and North Africa. The conquests and conquerors became legends due to the historical wonder they achieved.”
