In Our Time: History

Jane Francis, Richard Corfield and Carrie Lear join Melvyn Bragg to discuss ice ages, periods when a reduction in the surface temperature of the Earth has resulted in ice sheets at the Poles. Although the term 'ice age' is commonly associated with prehistoric eras when much of northern Europe was covered in ice, we are in fact currently in an ice age which began up to 40 million years ago. Geological evidence indicates that there have been several in the Earth's history, although their precise cause is not known. Ice ages have had profound effects on the geography and biology of our planet.With:Jane Francis Professor of Paleoclimatology at the University of LeedsRichard Corfield Visiting Research Fellow in the Department of Earth Sciences at Oxford UniversityCarrie Lear Senior Lecturer in Palaeoceanography at Cardiff University.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the War of 1812, the conflict between America and the British Empire sometimes referred to as the second American War of Independence. In June 1812, President James Madison declared war on Britain, angered by the restrictions Britain had imposed on American trade, the Royal Navy's capture of American sailors and British support for Native Americans. After three years of largely inconclusive fighting, the conflict finally came to an end with the Treaty of Ghent which, among other things, helped to hasten the abolition of the global slave trade. Although the War of 1812 is often overlooked, historians say it had a profound effect on the USA and Canada's sense of national identity, confirming the USA as an independent country. America's national anthem, The Star-Spangled Banner began life as a poem written after its author, Francis Scott Key, witnessed the British bombardment of Fort McHenry during the Battle of Baltimore. The war also led to Native Americans losing hundreds of thousands of acres of land in a programme of forced removal.

Melvyn Bragg and his guests discuss The South Sea Bubble, the speculation mania in early 18th-century England which ended in the financial ruin of many of its investors. The South Sea Company was founded in 1711 with a view to restructuring government debt and restoring public credit. The company would ostensibly trade with South America, hence its name; and indeed, it did trade in slaves for the Spanish market even after the Bubble burst in 1720. People from all walks of life bought shares in the South Sea Company, from servants to gentry, and it was said the entire country was gripped by South Sea speculation mania. When the shares crashed and the company collapsed there was a public outcry and many people faced financial ruin, although some investors sold before the crash and made substantial amounts of money. For example, the bookseller Thomas Guy made his fortune and founded a hospital in his name the following year. But how did such a financial crisis develop and were there any lessons learnt following this early example of a stock market boom and bust?With:Anne Murphy Senior Lecturer in History at the University of HertfordshireHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonRoey Sweet Head of the School of History at the University of LeicesterProducer: Natalia Fernandez.

Melvyn Bragg and his guests discuss the Borgias, the most notorious family in Renaissance Italy. Famed for their treachery and corruption, the Borgias produced two popes during their time of dominance in Rome in the late 15th century. The most well-known of these two popes is Alexander VI, previously Cardinal Rodrigo Borgia. He was accused of buying votes to elect him to the papacy and openly promoted his children in positions of power. Rodrigo's daughter, Lucrezia, is widely remembered as a ruthless poisoner; his son, Cesare, as a brutal soldier. Murder, intrigue and power politics characterised their rule, but many of the stories now told about their depraved behaviour and evil ways emerged after their demise and gave rise to the so-called 'Black Legend'. The sullied reputation of the Borgia dynasty endures even today and their lives have provided a major theme for plays, novels and over forty films.With:Evelyn Welch Professor of Renaissance Studies at Queen Mary, University of LondonCatherine Fletcher Lecturer in Public History at the University of SheffieldChristine Shaw Honorary Research Fellow at Swansea University Producer: Natalia Fernandez.

Hannibal, the Carthaginian general, led his army with elephants across the Alps to attack the Roman Republic. The podcast discusses his strategic military tactics, his rise to power, the crossing of the Alps, his victories in battles, the departure of an elite unit, and his symbolic significance as a figure of fear and destruction.

Melvyn Bragg and his guests discuss the medieval scholar Gerald of Wales. Born around the middle of the twelfth century, Gerald was a cleric and courtier. For much of his life he was close to Henry II and the Church hierarchy, and wrote accounts of official journeys he made around Wales and Ireland in their service. Both Anglo-Norman and Welsh by parentage, he had a unique perspective on the political strife of his age. Gerald's Journey Around Wales and Description of Ireland are among the most colourful and informative chronicles of the Middle Ages, and had a powerful influence on later historians.With:Henrietta Leyser Emeritus Fellow of St Peter's College, University of OxfordMichelle Brown Professor Emerita of Medieval Manuscript Studies at the School of Advanced Study, University of LondonHuw Pryce Professor of Welsh History at Bangor UniversityProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Druids, the priests of ancient Europe. Active in Ireland, Britain and Gaul, the Druids were first written about by Roman authors including Julius Caesar and Pliny, who described them as wearing white robes and cutting mistletoe with golden sickles. They were suspected of leading resistance to the Romans, a fact which eventually led to their eradication from ancient Britain. In the early modern era, however, interest in the Druids revived, and later writers reinvented and romanticised their activities. Little is known for certain about their rituals and beliefs, but modern archaeological discoveries have shed new light on them.With:Barry Cunliffe Emeritus Professor of Archaeology at the University of OxfordMiranda Aldhouse-Green Professor of Archaeology at Cardiff UniversityJustin Champion Professor of the History of Early Modern Ideas at Royal Holloway, University of LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Hadrian's Wall, the largest Roman structure and one of the most important archaeological monuments in Britain. Stretching for eighty miles from the mouth of the River Tyne to the Solway Firth and classified today as a World Heritage Site, it has been a source of fascination ever since it came into existence. It was built in about 122 AD by the Emperor Hadrian, and a substantial part of it still survives today. Although its construction must have entailed huge cost and labour, the Romans abandoned it within twenty years, deciding to build the Antonine Wall further north instead. Even after more than a century of excavations, many mysteries still surround Hadrian's Wall, including its exact purpose. Did it have a meaningful defensive role or was it mainly a powerful emperor's vanity project?

Melvyn Bragg and his guests discuss the life of the prominent 19th-century social reformer Annie Besant. Born in 1847, Annie Besant espoused a range of causes including secularism, women's rights, Socialism, Irish Home Rule, birth control and better conditions for workers. Described by Beatrice Webb as having "the voice of a beautiful soul", Besant became an eloquent public speaker as well as writing numerous campaigning articles and pamphlets. She is perhaps most famous for the key role she played in the successful strike by female workers at the Bryant and May match factory in East London in 1888, which brought the appalling working conditions of many factory workers to greater public attention. Later in life she became a follower of theosophy, a belief system bringing together elements of Hinduism, Buddhism and other Eastern religions. She moved to India, its main base, and took on a leading role in the Indian self-rule movement, being appointed the first female president of the Indian National Congress in 1917.

Melvyn Bragg and his guests discuss the An Lushan Rebellion, a major uprising against the imperial rule of the Chinese Tang Dynasty. In 755 AD a senior general, An Lushan, orchestrated a plot against Emperor Xuanzong, taking the regime's capital city before declaring a rival dynasty in northern China. The rebellion lasted eight years but was eventually put down by Tang forces. Although the dynasty's authority was restored, it never regained the prosperity of previous generations. The An Lushan Rebellion displaced millions of people and killed many more. It changed the relationship between the Chinese state and neighbouring powers; but it also left a rich cultural legacy in the poetry memorialising this seismic event.With:Frances WoodLead Curator of Chinese at the British LibraryNaomi StandenProfessor of Medieval History at the University of BirminghamHilde de WeerdtFellow and Lecturer in Chinese History at Pembroke College, Oxford.Producer: Thomas Morris.
