After the death of the Prophet Muhammad in 632 AD, a new era of Muslim conquests began. The Rashidun Caliphate, founded by Muhammad’s close companion Abu Bakr, spearheaded this expansion across the Middle East and the Mediterranean. Abu Bakr became the first Caliph, succeeding Muhammad with the support of the Muslims in Medina. Following him, Caliphs Umar, Uthman, and Ali continued to spread Islamic influence and faith.
During Abu Bakr’s leadership, some Arab tribes initiated the Ridda Wars, or Wars of Apostasy, against the caliphate. These tribes had pledged allegiance to Muhammad personally and, after his death, sought independence. Some leaders even claimed to be Muhammad’s rightful successors. Despite these challenges, Abu Bakr swiftly quelled the rebellions through a mix of military might and diplomacy, solidifying control over the Arabian Peninsula before turning his attention outward.
The campaigns in Iraq and Syria began towards the end of Abu Bakr’s rule. Al-Muthanna ibn Haritha, a local Arab chief, informed Abu Bakr of the potential for success in Iraq, prompting the Caliph to send his top commander, Khalid ibn al-Walid, to investigate. In 633, Abu Bakr also deployed troops to Syria, transforming initial raids into full-scale conquests. As the Byzantine Empire retaliated, Abu Bakr redirected Khalid to Syria to bolster the Rashidun forces.
Despite being outnumbered, the Muslim forces, led by Khalid, demonstrated remarkable military prowess. With around 20,000 troops, they faced a Byzantine army of 40,000 to 60,000 soldiers under Emperor Heraclius’ brother, Theodore. The Byzantines, expecting only minor tribal resistance, were caught off guard. While Byzantine sources minimize the significance of the Battle of Ajnadayn, Muslim accounts celebrate it as a decisive victory with substantial Byzantine losses.
After Abu Bakr’s death, Umar became Caliph. Despite Khalid’s key role in defeating the Byzantines, Umar appointed Abu Ubaidah as the new military commander in Syria. The Muslims captured Damascus, defeated the Byzantine garrison in Palestine, and took Emesa by 636. Emperor Heraclius was determined to stop the Rashidun expansion.
The Byzantines, with a diverse army of Greeks, Armenians, Georgians, Franks, Slavs, and Ghassanids, outnumbered the Muslims once again. The Byzantine force, led by Theodore Trithurius and Vahan, totaled around 40,000, while the Muslims had about 20,000 to 25,000 men. As the Byzantines tried to coordinate with their Sassanian allies, Abu Ubaidah ceded command back to Khalid, a proven strategist.
Khalid positioned his forces strategically near the Yarmouk River. Impatient with their allies, the Byzantines advanced alone. Initial negotiations lasted three months, allowing the Muslims to gather reinforcements. Eventually, both sides prepared for battle, with the Byzantine line stretching 13 kilometers and the Muslim line about 12 kilometers.
Both armies consisted of infantry, with the Byzantines relying on heavy troops and the Muslims on agile fighters. The first day saw individual duels, with Muslim warriors prevailing. Vahan attempted to break the Muslim front, but the Byzantines retreated by day’s end.
Vahan planned a surprise attack during Muslim morning prayers, but Khalid anticipated this and sent scouts. Initially, the Byzantines pushed the Muslims back, but the Rashidun women reportedly rallied their men, and Khalid reinforced the lines.
Over the following days, the Byzantines pressured the Muslims, but Khalid’s leadership held firm. By the fifth day, an Armenian commander sought peace, but Khalid refused and prepared for a decisive assault. He sent cavalry to block Byzantine escape routes, leading to renewed fighting.
The conflict resumed with a duel between Ubaidah and a Byzantine commander, resulting in a Muslim victory. This emboldened the Muslims to launch a full-scale attack, overwhelming the Byzantines, who fled unaware of blocked escape routes. The Byzantines suffered heavy losses, while Muslim casualties were minimal.
With this victory, the Rashidun Caliphate solidified its control over the Levant and the Arabian Peninsula. Jerusalem surrendered in 637, assured of safety. Despite Khalid’s contributions, Umar relieved him of military duties, attributing the victory to divine intervention. Khalid retired peacefully, choosing not to rebel.
From Muhammad’s death to Khalid’s discharge, the Muslims expanded their influence from Medina across the Arabian Peninsula and the Levant, with further campaigns into Anatolia and Armenia during Uthman’s reign. A key factor in the Rashidun’s success was the oppressive Byzantine rule, which led many locals to support the Muslim invaders in hopes of liberation. Khalid’s military expertise was crucial in these rapid conquests, setting the stage for continued expansion across the Middle East and beyond.

The death of the Prophet Muhammad in 632 AD led to a new wave of Muslim conquests across the region. The Rashidun Caliphate, established by Muhammad’s close friend, Abu Bakr, was the first to continue the Islamic expansion across the Middle East and the Mediterranean. After Muhammad’s passing, Abu Bakr became his successor, taking the title of Caliph with the agreement of the Muslims of Medina. Following Abu Bakr, Umar, Uthman, and Ali continued the Rashidun Caliphate and embarked on missions to spread their influence and faith.
During Abu Bakr’s reign, some Arab tribes engaged in the Ridda Wars, or Wars of Apostasy, against the caliphate’s forces. After Muhammad’s death, a few tribes broke ties with the caliphate, claiming their allegiance to Muhammad was personal. Some leaders even claimed to be his successors, leading to discord. Despite the military conflict, Abu Bakr and his forces quickly suppressed the rebellions through both warfare and diplomacy, consolidating their power over the Arabian Peninsula before shifting their focus outward.
The conquests of Iraq and Syria began towards the end of Abu Bakr’s reign. When a local Arab chief, Al-Muthanna ibn Haritha, informed Abu Bakr of the potential success in targeting Iraqi territories, the caliph sent his best commander, Khalid ibn al-Walid, to assess the situation. In 633, Abu Bakr also dispatched troops into Syria, and both missions escalated from raids to full conquests. Eventually, Abu Bakr redirected Khalid to Syria as the Rashidun troops faced retaliation from the Byzantine Empire, which had recently gained control of the region.
Despite being outnumbered, the Muslims demonstrated military superiority, reminiscent of the days of the Prophet Muhammad. The Muslim forces, led by Khalid, numbered around 20,000, while the Byzantines, commanded by Emperor Heraclius’ brother, Theodore, had between 40,000 to 60,000 troops. The Byzantine forces were caught off guard, expecting to face only a small group of local tribes. While Byzantine sources downplay the Battle of Ajnadayn, Muslim accounts celebrate it as a decisive victory, claiming significant losses for the Byzantines.
Shortly after this conflict, Abu Bakr passed away and was succeeded by Umar. Despite Khalid’s crucial role in the victory against the Byzantines, Umar appointed a new military commander, Abu Ubaidah, to lead the now-conquered Syria. The Muslims captured Damascus that same year, defeated the Byzantine garrison in Palestine the following year, and took Emesa in 636. The Byzantine Emperor, Heraclius, was determined to halt the Rashidun expansion.
Once again, the Byzantines outnumbered the Muslim troops, with a united force of Greeks, Armenians, Georgians, Franks, Slavs, and Ghassanid soldiers. The Byzantine army, led by Theodore Trithurius and Vahan, totaled around 40,000, while the Muslims had about 20,000 to 25,000 men. As the Byzantines attempted to coordinate their attack with their allies in the Sassanian Empire, Ubaidah, lacking confidence, relinquished command back to Khalid, who had proven himself as a seasoned commander.
Khalid positioned his forces strategically beyond the Yarmouk River. The Byzantines, growing impatient with their allies, decided to advance independently. Initial negotiations lasted about three months, allowing the Muslims to receive reinforcements. Eventually, both sides prepared for battle. The Byzantine army spread across approximately 13 kilometers, while the Muslims managed a front line of about 12 kilometers.
Both armies consisted of infantry, with the Byzantines having heavy troops while the Muslims relied on skilled and mobile fighters. The first day of fighting featured individual duels, with Muslim warriors emerging victorious. Vahan attempted to turn the tide by probing the Muslim front line, but the Byzantines retreated by the end of the day.
Determined to regain the initiative, Vahan planned an ambush during the Muslims’ morning prayers. However, Khalid anticipated this and sent scouts ahead. When the two forces clashed, the Byzantines initially gained the upper hand, pushing the Muslims back to their camps. However, the Rashidun women reportedly rallied their men back into battle, and Khalid provided reinforcements.
Over the next few days, the Byzantines continued to pressure the Muslim lines, but Khalid’s strategic leadership kept them at bay. By the fifth day, one of the Armenian commanders sought peace, but Khalid rejected the offer and prepared for a full assault. He sent cavalry to block the Byzantines’ escape route, leading to renewed fighting.
The conflict resumed with a duel between Ubaidah and a Byzantine commander, resulting in a Muslim victory. This encouraged the Muslim forces to launch a full-scale attack, overwhelming the Byzantines and forcing them to flee, unaware that escape routes had been cut off. The Byzantines suffered heavy losses, while the Muslims faced relatively few casualties.
With this victory, the Rashidun Caliphate solidified its control over the Levant and the Arabian Peninsula. Shortly thereafter, Jerusalem surrendered to the caliph in 637, having been promised safety. Despite Khalid’s significant contributions, he was discharged from military duties by Umar, who attributed the victory to divine intervention rather than Khalid’s tactics. Nevertheless, Khalid chose not to rebel and retired peacefully.
From Muhammad’s death to Khalid’s discharge, the Muslims expanded their influence and religion from Medina across the Arabian Peninsula and the Levant, with further campaigns into Anatolia and Armenia during Uthman’s reign. One key factor in the Rashidun’s early successes was the oppressive nature of the Byzantine Empire, which led many locals to support the Muslim invaders in hopes of liberation. Khalid’s military expertise played a vital role in these rapid conquests, positioning the Muslims favorably for continued expansion across the Middle East and beyond.
