By the spring of 1453, the Byzantine Empire had shrunk to almost nothing. Once it had ruled from Italy to the Middle East; now it was little more than a single city — Constantinople — and a few scraps of land nearby. Yet that city still mattered enormously. It sat where Europe meets Asia, guarding the water route between the Black Sea and the Mediterranean, and it had been the Christian capital of the East for over a thousand years.
Its greatest treasure was not gold but its walls. The Theodosian Walls, built in the fifth century, ran for miles across the landward side of the city: a deep ditch, then an outer wall, then a towering inner wall lined with dozens of towers. For a thousand years these fortifications had turned back army after army. To attackers, Constantinople looked simply unconquerable.
Facing the city was the Ottoman Empire, young, hungry and rising fast. Its new ruler, Sultan Mehmed II, had come to the throne at just twenty-one. Older advisers urged caution, but Mehmed was fixed on a single ambition: to take the city that had defied Muslim armies for eight centuries. Inside the walls, the last Byzantine emperor, Constantine XI, could gather only a few thousand defenders — his own soldiers and a band of Italian volunteers — to hold a city built for hundreds of thousands.
1. By 1453, how much of its old territory did the Byzantine Empire still control, and why did Constantinople still matter?
2. Who were the two leaders facing each other, and how did their strength compare?
1. Almost none — little more than the city itself and some nearby land. It still mattered because of its position between Europe and Asia, guarding the sea route, and its long history as the Christian capital of the East.
2. The young Ottoman Sultan Mehmed II, with a huge army, against the last Byzantine emperor Constantine XI, who had only a few thousand defenders for a vast city.
Mehmed had one advantage no earlier attacker had possessed: gunpowder artillery on a scale never seen before. A skilled cannon-maker named Orban, whose services the Byzantines had been unable to afford, built the Ottomans an enormous bronze cannon — so vast it took teams of oxen to move and could only be fired a handful of times a day. When it spoke, its stone balls smashed into the ancient walls with a force the medieval builders had never imagined.
The siege began in early April. Day after day the bombardment pounded the fortifications; each night the exhausted defenders repaired the damage with earth, rubble and wooden barrels, and each morning the guns began again. Out in the harbour, the great chain across the inlet known as the Golden Horn kept the Ottoman fleet at bay — for a time. Then Mehmed did something extraordinary: he had his ships dragged overland, on greased wooden rollers, over a hill and down into the Golden Horn behind the chain. Overnight the defenders found enemy ships in waters they had believed were safe, and now they had to guard the sea walls too.
The weeks dragged on. A promised rescue fleet from the West never came in force. The defenders were spread desperately thin along miles of wall, while the attacking army, vastly larger, could rest and rotate its men. Even so, wave after wave of assault was thrown back, and the walls — battered, breached, endlessly patched — somehow still held.
1. What advantage did Mehmed have that earlier attackers had not, and where had that advantage nearly gone instead?
2. How did the Ottomans get their ships past the great chain across the Golden Horn?
1. Huge gunpowder cannon. The cannon-maker Orban had first offered his skills to the Byzantines, but they could not afford him, so he built the great guns for the Ottomans instead.
2. Mehmed had the ships dragged overland on greased wooden rollers, over a hill and down into the Golden Horn behind the chain.
By late May the great guns had opened a wide breach near the middle of the land walls. On the night of 28 May, both sides knew the decisive attack was coming. Inside the city, people of different faiths gathered in the great church of Hagia Sophia to pray together, and the emperor spoke to his commanders one last time. Before dawn on 29 May 1453, Mehmed launched everything he had.
The first waves were driven back with heavy losses. But the attacks came in relentless succession, and in the confusion a small gate was found unbarred and defenders began to give way. When a leading Italian commander was wounded and carried from the wall, the defence near the breach faltered. Ottoman soldiers forced their way through, and the banners of the sultan rose over the towers. Constantine XI, the last emperor, is said to have thrown off the marks of his rank and died fighting in the streets, among his men; his body was never certainly identified.
By custom of the age, a city taken by storm was given over to plunder, and there were three hard days before Mehmed restored order. Then, aged just twenty-one, he rode to Hagia Sophia and turned the great church into a mosque, and made the city his new capital. A thousand-year empire, the last living thread of ancient Rome, had come to an end. To many across Europe it felt like the end of an era — and historians still often use that spring day to mark the close of the medieval world and the opening of a new age.
1. What is said to have happened to Constantine XI, the last emperor?
2. What did Mehmed do with the city and with Hagia Sophia after the fighting ended?
1. He is said to have removed the marks of his rank and died fighting alongside his soldiers in the streets; his body was never certainly identified.
2. He made Constantinople his new capital and turned the great church of Hagia Sophia into a mosque.
This whole story turns on a contradiction: a tiny, outnumbered garrison held the mightiest walls in the world against a vast army — and very nearly won. To tell it well, you need the linkers English uses to admit one fact and then push against it. That is exactly what concession linkers do.
Complete each sentence with although, even though, despite, in spite of or whereas. More than one may be possible — choose the one that fits best.
1. the walls were a thousand years old, they had never once been broken. (clause follows)
2. the constant bombardment, the defenders repaired the wall every night. (noun follows)
3. The attackers numbered in the tens of thousands, the defenders had only a few thousand men. (contrast of two facts)
1. Although / Even though (followed by a full clause)
2. Despite / In spite of (followed by a noun phrase)
3. whereas (setting two facts side by side)
Each sentence keeps the linker but has the wrong form after it. Write the corrected form of the words in brackets.
1. Despite (they were outnumbered), the garrison held for weeks. (despite needs a noun / -ing / "the fact that")
2. Even though (the size of the army), the first assaults were thrown back. (even though needs a clause)
3. In spite of (fight) bravely, the defenders could not hold the breach. (in spite of + -ing)
1. the fact that they were outnumbered (despite + "the fact that" + clause)
2. the army was huge (even though + full clause)
3. fighting (in spite of + -ing form)
Combine each pair into a single sentence using the linker in brackets. Read your answer aloud.
1. The rescue fleet was promised. It never arrived in force. (although)
2. The garrison was tiny. It held the walls for nearly two months. (despite)
3. Mehmed's army could rest and rotate. Constantine's men had no relief. (whereas)
1. Although the rescue fleet was promised, it never arrived in force.
2. Despite its tiny size, the garrison held the walls for nearly two months. (or: Despite being tiny… / Despite the fact that it was tiny…)
3. Mehmed's army could rest and rotate, whereas Constantine's men had no relief.
Remember: although / even though + clause; despite / in spite of + noun / -ing / "the fact that"; whereas sets two facts side by side.
Hold on to these — you'll need them in the Speak tab, where nearly every sentence is a contradiction waiting to be expressed.
You've read the story and you have the words — so now the real thing is within reach. There's a full podcast episode that tells this story in much greater depth, in natural, real-speed English. It's optional: the lesson stands on its own without it.

Tell the story of the fall of Constantinople in your own words, as if to someone who has never heard of it. Move through the arc: a thousand-year empire shrunk to one city → the great walls that had never fallen → the young sultan and his giant cannon → the ships dragged over the hill → the last assault and the end of an era.
Make the contradictions ring: use although, even though, despite, in spite of and whereas at the tense moments, and work in at least five key words (Byzantine, siege, fortifications, artillery, bombardment, garrison, boom, breach, sultan, epoch).
Historians argue about the single most important reason Constantinople fell: the giant cannon and new gunpowder technology; the sheer difference in numbers; the lack of help from the rest of Europe; or simple bad luck, like the unbarred gate. Build an argument for which mattered most, using whereas and although to weigh the factors against one another, and decide where you land.
The great cannon made the strongest walls in the world suddenly useless. Talk about a moment — in history or in your own field — when a new technology made an old, trusted defence or method obsolete overnight. Lean on the grammar: what held firm despite the pressure, what still worked even though it was old, and how the new way differed whereas the old way stayed the same.
