In the year 717 AD, a pivotal moment unfolded in Southern Europe, impacting Christian civilization profoundly. The Umayyad prince, Muslima ibn Abdul Malik, stood before the mighty walls of Constantinople, the capital of the Byzantine Empire, ready to launch an invasion. The timing seemed perfect; the Byzantine Empire was embroiled in internal strife. Between 711 and 717, three emperors had come and gone, and sectarian conflicts were tearing the empire apart. Additionally, the Byzantine Empire faced threats from the Bulgarian Khanate to the north and constant raids in Anatolia. It appeared that the remnants of ancient Rome were on the brink of collapse, with the Islamic Crescent poised to overshadow the Christian Cross. Yet, within those walls stood Emperor Leo III, known as the Lion of Rome, confident that his people would uphold their legacy.
To understand how this siege came about, we must look back 80 years to the reign of Emperor Heraclius. His rule was marked by fierce wars with the Sassanid Empire, which had overrun key regions like Syria, Palestine, Egypt, and Anatolia. The Persian army’s strength was finally broken during a failed siege of Constantinople. Although a peace treaty returned lost territories to the Byzantine Empire, the cost was immense. Both the Byzantine and Sassanid empires were left exhausted after 25 years of warfare.
During this time, a new force was rising in Arabia—the Muslim invasion. The Prophet Muhammad united various Arab tribes, and by his death in 662 AD, he had established a strong state with a clear mission: to spread Islam. His successors, the caliphs, continued this mission with great success. The Sassanid Empire fell within two decades, weakened by previous conflicts and internal issues. The Byzantine Empire lost crucial provinces like Syria and Palestine, which were vital for its economy, while Anatolia faced ongoing raids.
Despite these challenges, the Byzantine Empire survived the Arab siege of Constantinople in 678. Although hostilities decreased, they never truly ended, with Arabs conducting annual raids into Byzantine territories. This changed in 715 AD when Caliph Al-Walid ibn Abdul Malik made the conquest of Constantinople his main goal, believing that the city’s conqueror would be revered as a prophet.
The preparations for this campaign were extensive, with the Arab forces numbering between 80,000 and 120,000 soldiers and 1,200 to 1,800 ships. In response, Byzantine Emperor Anastasius II fortified Constantinople’s walls, stockpiled food, and increased the city garrison to about 15,000 men. The Byzantine Navy was also strengthened and equipped with Greek fire, a powerful weapon that burned on water and was highly effective in naval battles.
In 715, the first units of the Muslim army advanced into Byzantine-held Anatolia. Prince Muslima, leading the main Arab force, captured Sardis and Pergamon. Meanwhile, a Byzantine strategist from Anatolia, who would later become Emperor Leo III, secured support from the Umayyad prince by promising to become a vassal after the war. However, Leo had no intention of keeping this promise and prepared to fight the Arabs.
By early summer of 717, Muslima moved towards Constantinople, constructing two parallel walls for protection. However, Constantinople was no ordinary fortress; it was defended by formidable walls and a moat. The Arab fleet attempted to encircle the city, but the smaller, well-trained Byzantine Navy, armed with Greek fire, held its ground.
As winter set in, Muslima planned to renew his assault in the spring with fresh troops. However, the harsh winter conditions took a severe toll on the Arab forces, leading to hunger and disease. The Bulgarian ruler, honoring his treaty with the Byzantines, began attacking the Arab rear. Reinforcements promised by the Caliph arrived but faced defeat, and many sailors defected to the Byzantines.
Upon learning of these desertions, Leo ordered an attack on the weakened Arab fleet, which was further crippled by these losses. With no provisions and constant harassment from the Bulgarians, Muslima was recalled by the Caliph. The retreat was chaotic, and the Bulgarian forces struck fear into the remaining Arab troops.
The outcome was a significant victory for the Byzantines, with far-reaching consequences. Constantinople would not face another Arab threat, and the Umayyad dynasty would eventually be overthrown by the Abbasids about thirty years later. This victory not only preserved the Byzantine Empire but also marked a turning point in the history of Europe and the Islamic world.
Create a detailed map of the Siege of Constantinople in 717 AD. Include key locations such as the walls of Constantinople, the positions of the Byzantine and Arab forces, and the routes taken by the Bulgarian reinforcements. Use different colors to represent each faction and annotate the map with important events from the siege. This will help you visualize the strategic elements that contributed to the Byzantine victory.
Participate in a role-playing debate where you assume the roles of key figures from the siege, such as Emperor Leo III, Prince Muslima, and the Bulgarian Khan. Prepare arguments from your character’s perspective about the strategies and decisions made during the siege. This activity will deepen your understanding of the motivations and challenges faced by each side.
Conduct research on Greek fire, the Byzantine weapon that played a crucial role in the naval battles during the siege. Prepare a presentation that explains its composition, how it was used, and its impact on the outcome of the siege. Include visuals or demonstrations to make your presentation engaging and informative.
Create a timeline of events leading up to, during, and after the Siege of Constantinople in 717 AD. Highlight key moments such as the internal strife within the Byzantine Empire, the preparation of the Arab forces, and the turning points during the siege. This will help you understand the sequence of events and their historical significance.
Write an essay comparing the Siege of 717 AD with another historical siege, such as the Siege of Vienna in 1529. Analyze the similarities and differences in tactics, leadership, and outcomes. This exercise will enhance your critical thinking skills and provide a broader context for understanding military history.

[Music] The year is 717 AD, and a significant moment is upon Southern Europe and Christian civilization. Having marched his troops through Asia Minor and landed in front of the gates of Constantinople, the Umayyad prince, Muslima ibn Abdul Malik, gazed at the magnificent walls of the Byzantine capital and planned his next move. The time of invasion seemed favorable; the Byzantine Empire was in a state of internal conflict. From 711 to 717, three emperors rose to the throne and were subsequently deposed. Sectarian clashes sowed disunity among its people. The Empire faced the rising power of the Bulgarian Khanate to the north while fending off constant raids in Anatolia. It seemed that the last flicker of ancient Rome would finally be extinguished, and that the Crescent would eclipse the Cross. However, from those same walls, someone was looking back at him—confident in the thought that if all did their duty, they would live up to the legacy of their predecessors. That man was Emperor Leo III, known as the Lion of Rome.
To understand how this situation arose, we need to journey back 80 years to the reign of Emperor Heraclius. His reign was marked by devastating wars with the Sassanid Empire to the east, which had overrun Syria, Palestine, Egypt, and Anatolia. The might of the Persian army was finally broken by the failed siege of Constantinople. The subsequent peace treaty returned lost provinces to the Empire, but the cost of victory was high. Both the Byzantine and Sassanid empires were exhausted by 25 years of warfare.
While the greatest war of the early Middle Ages was being fought, something was brewing in Arabia—a storm that neither empire anticipated. That storm was the Muslim invasion. Having united various Arab tribes, the Prophet Muhammad, by the time of his death in 662 AD, left a strong state united by religion with a clear purpose: to spread the word of Islam. His successors, known as the caliphs, succeeded in this mission. The Sassanid Empire fell within two decades, weakened by previous conflicts and internal strife. The Byzantine Empire lost its most valuable provinces, Syria and Palestine, which were crucial for its revenues, while Anatolia faced constant raids.
However, after repelling the Arab siege of Constantinople in 678, the Empire survived. Following the siege, hostilities de-escalated but never truly ceased, as Arabs made annual raids into the remaining Byzantine territories. This changed in 715 AD with the rise of Caliph Al-Walid ibn Abdul Malik, who continued the expansionist policies of his predecessors. Al-Walid made the conquest of Constantinople his main objective, emboldened by the belief that the conqueror of the city would carry the name of a prophet.
Preparations for the campaign were extensive, with estimates of the Arab host ranging from 80,000 to 120,000 soldiers and 1,200 to 1,800 ships. The Byzantine Emperor Anastasius II, aware of the looming threat, began his own preparations. The walls of Constantinople were repaired and reinforced, food supplies were stockpiled, and the city garrison was increased to about 15,000 men. The Byzantine Navy was also enhanced and equipped with a powerful weapon known as Greek fire.
In 715, the first units of the Muslim army advanced across the Taurus Mountains into Byzantine-held Anatolia. Prince Muslima, with the main Arab force, occupied Sardis and Pergamon. Meanwhile, a strategist from the Byzantine theme of Anatolia, later known as Emperor Leo III, secured support from the Umayyad prince by promising to become a vassal after the war. However, Leo had no intention of honoring this promise and began preparing to fight the Arabs.
In early summer of 717, Muslima moved towards Constantinople, constructing two parallel walls for protection. However, Constantinople was no simple fortress; it was protected by formidable walls and a moat. The Arab fleet attempted to surround the city, but the Byzantine Navy, though smaller, was highly trained and equipped with Greek fire, a substance that burned on water and was effective in naval warfare.
As winter set in, Muslima planned to make his move in the spring with fresh troops. The harsh winter conditions took a toll on the Arab forces, leading to hunger and disease. The Bulgarian ruler honored his treaty with the Byzantines and began harassing the Arab rear. Reinforcements promised by the Caliph arrived, but they faced defeat, and many sailors defected to the Byzantines.
Upon hearing of these desertions, Leo ordered an attack on the Arab fleet, which was crippled by the losses. Constantinople was no longer threatened from the sea. With no provisions and constant harassment from the Bulgarians, Muslima was recalled by the Caliph. The retreat was chaotic, and the Bulgarian forces struck fear into the remaining Arab troops.
The outcome was a significant victory for the Byzantines, with repercussions felt far and wide. Constantinople would not be threatened by Arab forces again, and the Umayyad dynasty would eventually be deposed by the Abbasids some thirty years later.
