The story of Constantinople is the story  of over a thousand turbulent years,  

ending in a dramatic overthrow by the Ottoman  Empire. However, to understand its fall’s causes,  

we’ve got to return to its earliest roots  — Rome. When Emperor Diocletian divided  

the Roman Empire into two parts, the capital  chosen for the eastern half of the empire was  

the city then called Byzantium. This city would  come to bear the name of Emperor Constantine,  

who came to power in 330 AD, at the head of  what would become known as the Byzantine Empire.

Constantinople, standing at the Hellespont  — the strait which divides Europe from Asia  

Minor — rose with the eastern half of the broken  empire. Positioned at an advantageous point along  

the Silk Road, Constantinople grew in wealth and  trade. The city’s art and architecture reflected  

its grandeur and importance, including the  great cathedral known as the Hagia Sophia,  

or “holy wisdom,” built in 360. This building also  symbolized a change brought about by Constantine,  

who, unlike his predecessor, Diocletian, had made  Christianity the official religion of his empire.

At the crossroads between major cultural  influences, Constantinople was a vibrant  

and diverse place. At its height, the city was  filled with bustling markets and luxurious goods,  

such as ivory and silk. As a city with both  land and sea connections, Constantinople’s  

trade flourished, but so did the opportunities  for trouble. The Byzantine capital’s position  

made it a hotly contested spot, and in 717 AD, it  was besieged by ships from the Umayyad Caliphate,  

led by Malasma ibn Abd al-Malik. The attackers  were repelled by the powerful Byzantine navy,  

using Greek fire. This siege showed the  power wielded by the city and the strong  

defenses it possessed, but it was only an early  precursor of the continued turbulence to come.

In 1202, during the fourth crusade, the city  was sacked by crusaders, led by the son of the  

deposed emperor Isaac II Angelos. Many treasures  were destroyed in the pillaging that ensued. The  

sacking of the city was devastating, leaving an  estimated third of the city’s population homeless.

Still more destabilizing were the internal  conflicts. Schisms within the Christian  

church loomed early on and would have serious  consequences. The majority of these revolved  

around interpretations of various scriptures and  church rituals. Earlier, Constantine’s attempt to  

consolidate and establish the Christian church’s  beliefs had resulted in the Nicene Creed in 325,  

outlining the basics of the faith. However, it did  not have the unifying effect he had anticipated.  

The churches of Antioch, Constantinople,  and Rome all developed different beliefs  

and practices regarding using unleavened bread  for the Eucharist, the celebration of Easter,  

clerical celibacy, and the question of  who held ultimate religious authority.

Finally, the Great Schism sundered the  church. In 1054, Michael Cerularius,  

Patriarch of Constantinople, was excommunicated  by the Roman church. The Greek Orthodox church  

emerged on one side, and the Roman Catholic  church on the other. This would be a decisive  

blow to the Byzantine Empire’s power, with  Constantinople at its center. It would also  

destabilize allegiances and weaken bonds that  had once bolstered the empire’s position.

Tensions, both religious and political,  built over the next three centuries,  

and the Byzantine Empire splintered into  smaller states. By the mid-15th century,  

the city and empire had declined  from their former heights of power.  

The neighboring Ottoman Empire’s presence from  1299 onward was the source of another power  

struggle, one for which Constantinople stood on  the border, at the now chokepoint of the Bosporus.

The stage was set for battle, as the Ottomans  grew in strength and influence, and the Byzantines  

waned. It was time for the emperor, Constantine  XI, to seek help in defending the city.  

The major sea powers of Venice and Genoa, though  allied to Constantinople, each had their reasons  

for not being overly keen to help. All the  same, a fleet of Venetian ships was promised  

to Constantinople in their hour of need — but  it never arrived. The search for the ships  

yielded no results, and the searchers returned to  Constantinople, resigned to fight without them.

Genoa’s contribution was slightly more helpful  but still meager. Giovanni Giustiniani Longo, a  

Genoese captain, contributed 700 men, who marched  to the aid of Constantinople in January 1453.

Meanwhile, the emperor continued to scramble  to solidify allegiances and seek aid. An  

attempt at religious reunification failed,  despite the interests of Pope Nicholas V,  

who sought to regain control of the eastern half  of the church. The Orthodox leaders supported  

this reunion, but the idea failed to garner  widespread support, to where people rioted.

The internal conflict had worn  away at the base of the empire,  

and outside the walls, storms were ready to  break. Allies had been alienated during the  

centuries, and the empire’s power had declined  significantly. Weakened by its own troubles,  

Constantinople could not stand against the threats  that approached from outside — especially since  

those threats included an army led by a  keen strategist not about to back down.

Ottoman Sultan Mehmed II, at the age of only  twenty-one, was ambitious and powerful. Having  

constructed a fortress across the Bosporus,  controlling trade through the strait,  

he looked to strengthen his position, and in  1453, he decided to lay siege to Constantinople.  

However, taking lessons from the previous failure  several centuries earlier, he changed his tactics  

and employed the latest in battle technology  to turn the city’s own strengths against it.  

Previous sieges had been conducted with catapults,  trebuchets, and siege towers, but along with  

nearly 70 of these, he brought cannons powered  by gunpowder. The most powerful of these was  

described in hellish terms and brought out to the  horror of the Byzantines behind the city walls.

The Sultan’s allies included Saxon miners,  assigned to tunnel their way into the city,  

and elite infantry troops known as Janissaries.  

On April 5th, 1453, they made camp outside the  city walls and prepared to begin the siege.

As the Sultan’s forces gathered outside, the city  prepared itself as best it could for the attack.  

Fewer than 7,000 soldiers defended Constantinople  from within the walls, with between 30,000 and  

35,000 armed civilians — the defending troops were  drastically outnumbered. To give a sense of scale,  

the attacking army numbered over 100,000. Mehmed  II was ready to lead a fierce offensive against  

a city that, regardless of its strong  walls and long reign, was ready to fall.

Even the symbolic elements of the city seemed  to have turned against Constantinople’s  

citizens — an icon of the Virgin Mary,  long hailed as the protector of the city,  

was dropped during a parade attempting to  invoke her help. A thunderstorm only added  

to the building sense of doom. The Hagia Sophia  glowed red in the darkness of a lunar eclipse.

The siege lasted nearly two months.  Cannon fire bombarded the walls,  

focusing on the Romanus Gate. This was  the weakest point in the otherwise sturdy  

walls — and it was the point at which  the bombardment had the most effect.  

Though the great siege cannon cracked under  its own weight and heat, the smaller cannons,  

along with older siege weapons such as  trebuchets, took down the city’s defenses.

During the siege, Constantine XI was  encouraged by his councilors to flee the city,  

take refuge in Morea, and return  when he had regrouped his forces.  

He refused. As wave after wave of  troops hammered against the city walls,  

morale dropped, and the defending forces  realized that they were in this to the end.

On May 29th, 1453, the final  attack of the siege took place.  

Over a thousand years of empire ended in a burst  of cannon fire. Despite conflict and strife,  

the walls had never been breached; now, they  were overthrown, and the city was conquered.  

Towards the end of the fighting, as the situation  grew more desperate, Emperor Constantine XI was  

killed. It is uncertain exactly where he met his  end, but some say he had stripped off all that  

marked him as the emperor and was only identified  by way of imperial symbols on his boots.

The Ottoman Empire had won. The  reign of the Byzantines was over.

The immediate result of the siege was death and  destruction for residents and buildings. Though  

Mehmed II did not wish his forces to utterly sack  the city, there were scenes of violent looting,  

and eyewitness accounts describe horrific  scenes following the surrender of the city.  

The Sultan himself rode to the Hagia  Sophia, allowed those hiding within to  

leave with an escort, converted it to the mosque  Ayasofia, and demanded that the looting cease.

In the long term, transferring power from the  Byzantines to the Ottomans in Constantinople meant  

that the city became the capital of the Ottoman  Empire, which, at its height ,extended throughout  

much of eastern Europe, northern Africa, and parts  of the Middle East. The siege itself, with its  

new weaponry and use of gunpowder, also changed  the history of warfare forever. Some historians  

use this turning point to mark the end of the  Middle Ages and the beginning of the Renaissance.
