In 6 19, King Khosrau II of Sassanian Dynasty occupied Egypt and expanded Persian territory to an unprecedented extent. At this time, he probably wouldn't have thought that his opponent, Emperor Chirac, would make a comeback and would not have a good end in the end. He didn't even think that just when he was full of ambition, a guy named Muhammad on the Arabian Peninsula created a new religion. The green hurricane blown by this religion for more than ten years will sweep his country!
At the beginning of the 7th century, Arabs were still in a clan society and mainly believed in polytheism. The Arabian Peninsula where they live is barren and the climate is harsh. Most residents are nomads, living on water and grass. Since the 6th century AD, the western part of Arabia has been the object of contention between Byzantium and Persia, and the two empires have been fighting with each other.
According to legend, one day in June10, Muhammad was 40 years old. While he was meditating in the cave of Mount Sheila on the outskirts of Mecca, God sent the angel Gabriel to convey "enlightenment" to him and made him "ordained". From then on, he announced that he accepted the "mission" entrusted by Allah and began a 23-year campaign to spread Islam. After the Arabian Peninsula unification war, the Arabs established the Arab Empire in the Arabian Peninsula, and then the Arabs launched a vigorous conquest movement.
When the Arabs launched their foreign conquest, the Persian Sassanian Empire and the Byzantine Empire were in a protracted war, which made the two empires empty and exhausted.
After the death of Prophet Muhammad, Abu Birkel became the successor caliph. His succession not only marks the beginning of the era of the four caliphs of the Arab Empire, but also marks the arrival of the era of Arab expansion.
At first, because the Muslims' first choice targets were Syria under the Byzantine Empire and the Christian Arab vassal States in the southern part of the two river basins, they put their main strength into the battle with the Byzantine Empire and did not have much energy to take care of the Sassanian Dynasty. However, when they won a series of victories in Syria, the nightmare of Sassanian dynasty began.
At this time, sassanian dynasty has got rid of the chaos after Khosrau II's death. After Ihail III succeeded to the throne, he took various measures to restore the chaotic economy caused by the war, and at the same time made a little reconciliation with the Byzantine emperor Chirac, so the Persian national strength was restored to a certain extent.
When he first learned about the attacks by southern Muslims, he didn't take these vagrants seriously. However, a series of news of defeat soon reached his court, especially Sheila, a small town with extremely important strategic position, which made him extremely angry. The king of Persia immediately sent General rustam to recover the lost territory.
