Melvyn Bragg and guests discuss Abraham Lincoln's Gettysburg Address, ten sentences long, delivered at the dedication of the Soldiers' National Cemetery at Gettysburg after the Union forces had won an important battle with the Confederates. Opening with " Four score and seven years ago," it became one of the most influential statements of national purpose, asserting that America was "conceived in liberty, and dedicated to the proposition that all men are created equal" and "that this nation, under God, shall have a new birth of freedom-and that government of the people, by the people, for the people, shall not perish from the earth." Among those inspired were Martin Luther King Jr whose "I have a dream" speech, delivered at the Lincoln Memorial 100 years later, echoed Lincoln's opening words.With Catherine Clinton Denman Chair of American History at the University of Texas and International Professor at Queen's University, BelfastSusan-Mary Grant Professor of American History at Newcastle UniversityAndTim Lockley Professor of American History at the University of WarwickProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Titus Oates (1649-1705) who, with Israel Tonge, spread rumours of a Catholic plot to assassinate Charles II. From 1678, they went to great lengths to support their scheme, forging evidence and identifying the supposed conspirators. Fearing a second Gunpowder Plot, Oates' supposed revelations caused uproar in London and across the British Isles, with many Catholics, particularly Jesuit priests, wrongly implicated by Oates and then executed. Anyone who doubted him had to keep quiet, to avoid being suspected a sympathiser and thrown in prison. Oates was eventually exposed, put on trial under James II and sentenced by Judge Jeffreys to public whipping through the streets of London, but the question remained: why was this rogue, who had faced perjury charges before, ever believed?WithClare Jackson Senior Tutor and Director of Studies in History at Trinity Hall, University of CambridgeMark Knights Professor of History at the University of WarwickAndPeter Hinds Associate Professor of English at Plymouth UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the impact of the eruption of Mt Tambora, in 1815, on the Indonesian island of Sambawa. This was the largest volcanic eruption in recorded history and it had the highest death toll, devastating people living in the immediate area. Tambora has been linked with drastic weather changes in North America and Europe the following year, with frosts in June and heavy rains throughout the summer in many areas. This led to food shortages, which may have prompted westward migration in America and, in a Europe barely recovered from the Napoleonic Wars, led to widespread famine.

Melvyn Bragg and guests discuss the rise of the Sikh Empire at the end of the 18th Century under Ranjit Singh, pictured above, who unified most of the Sikh kingdoms following the decline of the Mughal Empire. He became Maharaja of the Punjab at Lahore in 1801, capturing Amritsar the following year. His empire flourished until 1839, after which a decade of unrest ended with the British annexation. At its peak, the Empire covered the Punjab and stretched from the Khyber Pass in the west to the edge of Tibet in the east, up to Kashmir and down to Mithankot on the Indus River. Ranjit Singh is still remembered as "The Lion of the Punjab."With Gurharpal Singh Professor in Inter-Religious Relations and Development at SOAS, University of LondonChandrika Kaul Lecturer in Modern History at the University of St AndrewsAndSusan Stronge Senior Curator in the Asian Department of the Victoria and Albert MuseumProducer: Simon Tillotson.

Agrippina the Younger was one of the most notorious and influential of the Roman empresses in the 1st century AD. She was the sister of the Emperor Caligula, a wife of the Emperor Claudius and mother of the Emperor Nero. Through careful political manoeuvres, she acquired a dominant position for herself in Rome. In 39 AD she was exiled for allegedly participating in a plot against Caligula and later it was widely thought that she killed Claudius with poison. When Nero came to the throne, he was only 16 so Agrippina took on the role of regent until he began to exert his authority. After relations between Agrippina and Nero soured, he had her murdered.With:Catharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonAlice König Lecturer in Latin and Classical Studies at the University of St AndrewsMatthew Nicholls Associate Professor of Classics at the University of ReadingProducer: Victoria Brignell.

Melvyn Bragg and guests discuss the early years of Bedlam, the name commonly used for the London hospital of St Mary of Bethlehem outside Bishopsgate, described in 1450 by the Lord Mayor of London as a place where may "be found many men that be fallen out of their wit. And full honestly they be kept in that place; and some be restored onto their wit and health again. And some be abiding therein for ever." As Bethlem, or Bedlam, it became a tourist attraction in the 17th Century at its new site in Moorfields and, for its relatively small size, made a significant impression on public attitudes to mental illness. The illustration, above, is from the eighth and final part of Hogarth's 'A Rake's Progress' (1732-3), where Bedlam is the last stage in the decline and fall of a young spendthrift,Tom Rakewell.With Hilary Marland Professor of History at the University of WarwickJustin Champion Professor of the History of Early Modern Ideas at Royal Holloway, University of London and President of the Historical AssociationAndJonathan Andrews Reader in the History of Psychiatry at Newcastle UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Maya Civilization, developed by the Maya people, which flourished in central America from around 250 AD in great cities such as Chichen Itza and Uxmal with advances in mathematics, architecture and astronomy. Long before the Spanish Conquest in the 16th Century, major cities had been abandoned for reasons unknown, although there are many theories including overpopulation and changing climate. The hundreds of Maya sites across Belize, El Salvador, Guatemala, Honduras and Mexico raise intriguing questions about one of the world's great pre-industrial civilizations.WithElizabeth Graham Professor of Mesoamerican Archaeology at University College LondonMatthew Restall Edwin Erle Sparks Professor of Latin American History and Anthropology at Pennsylvania State UniversityAndBenjamin Vis Eastern ARC Research Fellow in Digital Humanities at the University of KentProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Vereenigde Oost-Indische Compagnie or VOC, known in English as the Dutch East India Company. The VOC dominated the spice trade between Asia and Europe for two hundred years, with the British East India Company a distant second. At its peak, the VOC had a virtual monopoly on nutmeg, mace, cloves and cinnamon, displacing the Portuguese and excluding the British, and were the only European traders allowed access to Japan.With Anne Goldgar Reader in Early Modern European History at King's College LondonChris Nierstrasz Lecturer in Global History at Erasmus University, Rotterdam, formerly at the University of WarwickAndHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonProducer: Simon Tillotson.

Learn about the historical context in which she was born, the rumors and narratives surrounding her, and her struggle for recognition.

Melvyn Bragg and guests discuss Thomas Paine and his pamphlet "Common Sense" which was published in Philadelphia in January 1776 and promoted the argument for American independence from Britain. Addressed to The Inhabitants of America, it sold one hundred and fifty thousand copies in the first few months and is said, proportionately, to be the best-selling book in American history. Paine had arrived from England barely a year before. He vigorously attacked monarchy generally and George the Third in particular. He argued the colonies should abandon all hope of resolving their dispute with Britain and declare independence immediately. Many Americans were scandalised. More were inspired and, for Paine's vision of America's independent future, he has been called a Founding Father of the United States.With Kathleen Burk Professor Emerita of Modern and Contemporary History at University College LondonNicholas Guyatt University Lecturer in American History at the University of CambridgeAndPeter Thompson Associate Professor of American History at the University of Oxford and Fellow of St Cross CollegeProducer: Simon Tillotson.
