Melvyn Bragg and guests discuss one of the most celebrated thinkers of the twentieth century. Walter Benjamin (1892-1940) was a German Jewish philosopher, critic, historian, an investigator of culture, a maker of radio programmes and more. Notably, in his Arcades Project, he looked into the past of Paris to understand the modern age and, in The Work of Art in the Age of Mechanical Reproduction, examined how the new media of film and photography enabled art to be politicised, and politics to become a form of art. The rise of the Nazis in Germany forced him into exile, and he worked in Paris in dread of what was to come; when his escape from France in 1940 was blocked at the Spanish border, he took his own life.

Melvyn Bragg and guests discuss the momentum behind teetotalism in 19th Century Britain, when calls for moderation gave way to complete abstinence in pursuit of a better life. Although arguments for temperance had been made throughout the British Isles beforehand, the story of the organised movement in Britain is often said to have started in 1832 in Preston, when Joseph Livesey and seven others gave a pledge to abstain. The movement grew quickly, with Temperance Halls appearing as new social centres in towns in place of pubs, and political parties being drawn into taking sides either to support abstinence or impose it or reject it. The image above, which appeared in The Teetotal Progressionist in 1852, is an example of the way in which images contained many points of temperance teaching, and is © Copyright Livesey Collection at the University of Central Lancashire.

Melvyn Bragg and guests discuss one of the outstanding French writers of the twentieth century. The novels of Sidonie-Gabrielle Colette (1873 - 1954) always had women at their centre, from youth to mid-life to old age, and they were phenomenally popular, at first for their freshness and frankness about women’s lives, as in the Claudine stories, and soon for their sheer quality as she developed as a writer. Throughout her career she intrigued readers by inserting herself, or a character with her name, into her works, fictionalising her life as a way to share her insight into the human experience.With Diana Holmes Professor of French at the University of LeedsMichèle Roberts Writer, novelist, poet and Emeritus Professor of Creative Writing at the University of East AngliaAndBelinda Jack Fellow and Tutor in French Literature and Language at Christ Church, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the system that flourished from 1870 when gold became dominant and more widely available, following gold rushes in California and Australia. Banknotes could be exchanged for gold at central banks, the coins in circulation could be gold (as with the sovereign in the image above, initially worth £1), gold could be freely imported and exported, and many national currencies around the world were tied to gold and so to each other. The idea began in Britain, where sterling was seen as good as gold, and when other countries rushed to the Gold Standard the confidence in their currencies grew, and world trade took off and, for a century, gold was seen as a vital component of the world economy, supporting stability and confidence. The system came with constraints on government ability to respond to economic crises, though, and has been blamed for deepening and prolonging the Great Depression of the 1930s.

Melvyn Bragg and guests discuss Thomas Hardy (1840 -1928) and his commitment to poetry, which he prized far above his novels. In the 1890s, once he had earned enough from his fiction, Hardy stopped writing novels altogether and returned to the poetry he had largely put aside since his twenties. He hoped that he might be ranked one day alongside Shelley and Byron, worthy of inclusion in a collection such as Palgrave's Golden Treasury which had inspired him. Hardy kept writing poems for the rest of his life, in different styles and metres, and he explored genres from nature, to war, to epic. Among his best known are what he called his Poems of 1912 to 13, responding to his grief at the death of his first wife, Emma (1840 -1912), who he credited as the one who had made it possible for him to leave his work as an architect's clerk and to write the novels that made him famous.WithMark Ford Poet, and Professor of English and American Literature, University College London.Jane Thomas Emeritus Professor of English at the University of Hull and Senior Visiting Research Fellow at the University of LeedsAnd Tim Armstrong Professor of Modern English and American Literature at Royal Holloway, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the Austrian-born film director Fritz Lang (1890-1976), who was one of the most celebrated film-makers of the 20th century. He worked first in Weimar Germany, creating a range of films including the startling and subversive Mabuse the Gambler and the iconic but ruinously expensive Metropolis before arguably his masterpiece, M, with both the police and the underworld hunting for a child killer in Berlin, his first film with sound. The rise of the Nazis prompted Lang's move to Hollywood where he developed some of his Weimar themes in memorable and disturbing films such as Fury and The Big Heat.

Melvyn Bragg and guests discuss the empire that flourished in the Late Bronze Age in what is now Turkey, and which, like others at that time, mysteriously collapsed. For the next three thousand years these people of the Land of Hatti, as they called themselves, were known only by small references to their Iron Age descendants in the Old Testament and by unexplained remains in their former territory. Discoveries in their capital of Hattusa just over a century ago brought them back to prominence, including cuneiform tablets such as one (pictured above) which relates to an agreement with their rivals, the Egyptians. This agreement has since become popularly known as the Treaty of Kadesh and described as the oldest recorded peace treaty that survives to this day, said to have followed a great chariot battle with Egypt in 1274 BC near the Orontes River in northern Syria.

Melvyn Bragg and guests discuss Charles Dickens' novella, written in 1843 when he was 31, which has become intertwined with his reputation and with Christmas itself. Ebenezer Scrooge is the miserly everyman figure whose joyless obsession with money severs him from society and his own emotions, and he is only saved after recalling his lonely past, seeing what he is missing now and being warned of his future, all under the guidance of the ghosts of Christmases Past, Present and Yet To Come. Redeemed, Scrooge comes to care in particular about one of the many minor characters in the story who make a great impact, namely Tiny Tim, the disabled child of the poor and warm-hearted Cratchit family, with his cry, "God bless us, every one!"WithJuliet John Professor of English Literature and Dean of Arts and Social Sciences at City, University of LondonJon Mee Professor of Eighteenth-Century Studies at the University of YorkAndDinah Birch Pro-Vice-Chancellor for Cultural Engagement and Professor of English Literature at the University of LiverpoolProducer: Simon Tillotson

Melvyn Bragg and guests discuss the violent protests in China on 4th May 1919 over the nation's humiliation in the Versailles Treaty after World War One. China had supported the Allies, sending workers to dig trenches, and expected to regain the German colonies on its territory, but the Allies and China's leaders chose to give that land to Japan instead. To protestors, this was a travesty and reflected much that was wrong with China, with its corrupt leaders, division by warlords, weakness before Imperial Europe and outdated ideas and values. The movement around 4th May has since been seen as a watershed in China’s development in the 20th century, not least as some of those connected with the movement went on to found the Communist Party of China a few years later.The image above is of students from Peking University marching with banners during the May Fourth demonstrations in 1919.With Rana Mitter Professor of the History and Politics of Modern China and Fellow of St Cross College, University of OxfordElisabeth Forster Lecturer in Chinese History at the University of SouthamptonAnd Song-Chuan Chen Associate Professor in History at the University of WarwickProducer: Simon Tillotson

Melvyn Bragg and guests discuss the events of 21st October 1805, in which the British fleet led by Nelson destroyed a combined Franco-Spanish fleet in the Atlantic off the coast of Spain. Nelson's death that day was deeply mourned in Britain, and his example proved influential, and the battle was to help sever ties between Spain and its American empire. In France meanwhile, even before Nelson's body was interred at St Paul's, the setback at Trafalgar was overshadowed by Napoleon's decisive victory over Russia and Austria at Austerlitz, though Napoleon's search for his lost naval strength was to shape his plans for further conquests.The image above is from 'The Battle of Trafalgar' by JMW Turner (1824).WithJames Davey Lecturer in Naval and Maritime History at the University of ExeterMarianne Czisnik Independent researcher on Nelson and editor of his letters to Lady HamiltonAndKenneth Johnson Research Professor of National Security at Air University, AlabamaProducer: Simon Tillotson
