Melvyn Bragg and guests discuss the Roman historian Tacitus who chronicled some of Rome’s most notorious emperors, including Nero and Caligula, and whose portrayal of Roman decadence influences the way we see Rome today. “The story I now commence is rich in vicissitudes, grim with warfare, torn by civil strife, a tale of horror even during times of peace”. So reads page one of The Histories by the Roman historian Tacitus and it doesn’t disappoint. Convinced that Rome was going to the dogs, Tacitus depicts a Rome which is a hotbed of sex and violence, of excessive wealth and senatorial corruption. His work is a pungent study in tyranny and decline that has influenced depictions of Rome, from Gibbon’s Decline and Fall to Robert Graves’ I, Claudius. But is it a true picture of the age or does Tacitus’ work present the tyranny and decadence of Rome at the expense of its virtues? And to what extent, when we look at the Roman Empire today, do we still see it through Tacitus' eyes?With Catharine Edwards, Professor of Classics and Ancient History at Birkbeck, University of London; Ellen O’Gorman, Senior Lecturer in Classics at the University of Bristol and Maria Wyke, Professor of Latin at University College London

Melvyn Bragg and guests discuss the Arab conquests - an extraordinary period in the 7th and 8th centuries when the tribes of the Arabian Peninsula conquered the Middle East, Persia, North Africa and Southern Europe and spread the ideas of the Islamic religion. In 632 the prophet Muhammad died and left behind the nascent religion of Islam among a few tribes in the Arabian Desert. They were relatively small in number, they were divided among themselves and they were surrounded by vast and powerful empires. Yet within 100 years Arab armies controlled territory from Northern Spain to Southern Iran and Islamic ideas had begun to profoundly refashion the societies they touched. It is one of the most extraordinary and significant events in world history that began the slow and profound transformation of Greek and Persian societies into Islamic ones. But how did the Arab armies achieve such extensive victories, how did they govern the people they conquered and what was the relationship between the achievements of the Arabs and the religious beliefs they carried with them?With Hugh Kennedy, Professor of Arabic at the School of Oriental and African Studies, University of London; Amira Bennison, Senior Lecturer in Middle Eastern and Islamic Studies at the University of Cambridge and Robert Hoyland, Professor in Arabic and Middle East Studies at the University of St Andrews

Melvyn Bragg and guests discusses the prescient thriller ‘The Riddle of the Sands’ about the decline Anglo-German relations before the First World War. In 1903 an Englishman called Charles Caruthers went sailing in the North Sea and stumbled upon a German military plot. The cunning plan was to invade the British Isles from the Frisian Islands using special barges. The plucky Caruthers foiled the plot and returned to his sailing holiday.This is not history but fiction, an immensely popular book called ‘The Riddle of the Sands’ by Erskine Childers. It was a prescient vision of two nations soon to fight the First World War but it went against the spirit of the previous century. Brits and Germans had fought together at Waterloo and had influenced profoundly each other’s thought and art. They even shared a royal family. Yet somehow victory at Waterloo and the shared glories of Romanticism became the mutual tragedy of the Somme.With Richard Evans, Professor of Modern History at the University of Cambridge; Rosemary Ashton, Quain Professor of English Language and Literature at University College London and Tim Blanning, Professor of Modern European history at The University of Cambridge.

Melvyn Bragg and guests discuss how the Black Death influenced the structure and ideas of Medieval Europe. In October 1347, a Genoese trading ship arrived at the busy port of Messina in Sicily and docked among many similar ships doing similar things. But this ship was special because this ship had rats and the rats had fleas and the fleas had plague. This was the Black Death and its terrible progress was captured by the Florentine writer Giovanni Boccaccio who declared “in those years a dead man was then of no more account than a dead goat”. In the long and unsanitary history of Europe there have been many plagues but only one Black Death. It killed over a third of Europe’s population in 4 years – young and old, rich and poor, in the town and in the country. When it stopped in 1351 it left a continent ravaged but transformed – the poor found their labour to be valuable, religion was both reinforced and undercut, medicine progressed, art changed and the continent awash with guilt and memorialisation. With Miri Rubin, Professor of Medieval and Early Modern History at Queen Mary, University of London; Samuel Cohn, Professor of Medieval History at the University of Glasgow; Paul Binski, Professor of the History of Medieval Art at Gonville and Caius College, University of Cambridge

Melvyn Bragg and guests discuss the enclosure movement of the 18th and 19th centuries. In the early 19th century, the Northamptonshire poet John Clare took a good look at the countryside and didn’t like what he saw. He wrote: "Fence meeting fence in owners little boundsOf field and meadow, large as garden-grounds,In little parcels little minds to please,With men and flocks imprisoned, ill at ease."Enclosure means literally enclosing a field with a fence or a hedge to prevent others using it. This seemingly innocuous act triggered a revolution in land holding that dispossessed many, enriched a few but helped make the agricultural and industrial revolutions possible. It saw the dominance of private property as the model of ownership, as against the collective rights of previous generations. For some Enclosure underpinned the economic and agricultural development of Modern Britain. But it has also been a cause celebre for the political left ever since Karl Marx argued that enclosures created the industrialised working class and ushered in the capitalist society. What really happened during the era of 18th and 19th century enclosures? Who gained, who lost and what role did Enclosures play in the agricultural and industrial transformation of this country? With Rosemary Sweet, Director of the Centre for Urban History at the University of Leicester; Murray Pittock, Bradley Professor of English Literature at the University of Glasgow; Mark Overton, Professor of Economic and Social History at the University of Exeter.

Melvyn Bragg and guests discuss ‘the Norman Yoke’ – the idea that the Battle of Hastings sparked years of cruel oppression for the Anglo Saxons by a Norman ruling class. ‘Norman saw on English oak,On English neck a Norman yoke;Norman spoon in English dish,And England ruled as Normans wish.’Taken from Sir Walter Scott’s novel ‘Ivanhoe’, these words encapsulate the idea of ‘the Norman Yoke’ – that the Battle of Hastings sparked the cruel oppression of Anglo-Saxon liberties by a foreign ruling class. Certainly, William the Conqueror proclaimed his power in great castles and cathedrals, turned the church upside down and even changed the colour of scribal ink. But was it really such a terrible time for the Anglo Saxons or was the idea of beastly Norman oppressors and noble Saxon sufferers invented later to shore up the idea of Englishness? With Sarah Foot, Regius Professor of Ecclesiastical History at Christ Church, Oxford; Richard Gameson, Professor in the Department of History at Durham University; Matthew Strickland, Professor of Medieval History at the University of Glasgow.

Melvyn Bragg and guests discuss Henry VIII and the Dissolution of the Monasteries. Was Henry’s decision to destroy monastic culture in this country a tyrannical act of grand larceny or the pious destruction of a corrupt institution? When he was an old man, Michael Sherbrook remembered the momentous events of his youth: “All things of price were either spoiled, plucked away or defaced to the uttermost…it seemed that every person bent himself to filch and spoil what he could. Nothing was spared but the ox-houses and swincotes…” He was talking about the destruction of Roche Abbey, but it could have been Lewes or Fountains, Glastonbury, Tintern or Walsingham, names that haunt the religious past as their ruins haunt the landscape. These were the monasteries, suddenly and for many shockingly, destroyed during the reign of Henry VIII.The conflict was played out with a mix of violence, heroism, political manoeuvring and genuine theological disputation. But what was lost in terms of architecture, painting, treasure and in the religious habits of the monasteries themselves and of the common people who lived with them?With Diarmaid MacCulloch, Professor of the History of the Church at Oxford University; Diane Purkiss, Fellow and Tutor at Keble College, Oxford; George Bernard, Professor of Early Modern History at the University of Southampton

Melvyn Bragg and guests discuss the Statue of Liberty."Give me your tired, your poor, your huddled masses yearning to breathe free”. With these words, inscribed inside her pedestal, the Statue of Liberty has welcomed immigrants to America since 1903. But the Statue of Liberty is herself an immigrant, born in Paris she was shipped across the Atlantic in 214 separate crates, a present to the Americans from the French. She is a token of friendship forged in the fire of twin revolutions, finessed by thinkers like Alexis de Tocqueville and expressed in the shared language of liberty. But why was this colossal statue built, who built it and what did liberty mean to the Frenchmen who created her and the Americans who received her?With Robert Gildea, Professor of Modern History at Oxford University; Kathleen Burk, Professor of Modern Contemporary History at University College London; John Keane, Professor of Politics at the University of Westminster

Melvyn Bragg and guests discuss the coterie of brilliant thinkers gathered in 16th century Prague by the melancholic emperor Rudolph II. In 1606 the Archdukes of Vienna declared: “His majesty is interested only in wizards, alchemists, Kabbalists and the like, sparing no expense to find all kinds of treasures, learn secrets and use scandalous ways of harming his enemies…He also has a whole library of magic books. He strives all the time to eliminate God completely so that he may in future serve a different master.”The subject of this coruscating attack was the Holy Roman Emperor, Rudolf II, and his court at Prague. Rudolph had turned Prague into a collector’s cabinet for the wonders and curiosities of the age – the great paintings of Northern Italy were carried to him over the Alps, intricate automatons constructed to serve drinks, maps and models of the heavens were unwound and engineered as the magnificent city of Prague itself was rebuilt in the image of its dark and thoughtful patron in chief. But Rudolf’s greatest possessions were people - the astronomers Johannes Kepler and Tycho Brahe, the magus John Dee and the philosopher Giordano Bruno had all found their way to his city. Far from the devilish inquisitor of the archdukes’ imaginations, Rudolf patronised a powerhouse of Renaissance ideas. With Peter Forshaw, Postdoctoral Fellow at Birkbeck, University of London and an Honorary Fellow of the University of Exeter; Howard Hotson, Lecturer in Modern History at the University of Oxford; Adam Mosley, Lecturer in the Department of History at the University of Wales, Swansea.

Melvyn Bragg and guests discuss the Charge of the Light - an event of no military significance that has become iconic in the British historical imagination. On November 14th 1854 The Times newspaper reported on a minor cavalry skirmish in the Crimean War: “They swept proudly past, glittering in the morning sun in all the pride and splendour of war... At the distance of 1200 yards the whole line of the enemy belched forth, from thirty iron mouths, a flood of smoke and flame through which hissed the deadly balls. Their flight was marked by instant gaps in our ranks, by dead men and horses, by steeds flying wounded or riderless across the plain”.This is the debacle of the Charge of the Light Brigade, which made little difference to the Crimean War yet has become deeply embedded in British culture. It helped to provoke the resignation of a Prime Minister and it profoundly changed British attitudes to war and to the soldiers who fought in them. It also brought censorship to bear on previously uncensored war reporting and inspired Alfred, Lord Tennyson to sit down and write “All in the Valley of Death rode the six hundred”.With Mike Broers, Lecturer in Modern History at the University of Oxford and a Fellow of Lady Margaret Hall; Trudi Tate, Fellow of Clare Hall, Cambridge; Saul David, Visiting Professor of Military History at the University of Hull
