Melvyn Bragg and guests discuss the most powerful woman in the Crusader states in the century after the First Crusade. Melisende (1105-61) was born and raised after the mainly Frankish crusaders had taken Jerusalem from the Fatimids, and her father was King of Jerusalem. She was married to Fulk from Anjou, on the understanding they would rule together, and for 30 years she vied with him and then their son as they struggled to consolidate their Frankish state in the Holy Land. The image above is of the coronation of Fulk with Melisende, from Livre d'Eracles, Guillaume de Tyr (1130?-1186) Source: Bibliothèque nationale de France With Natasha Hodgson Senior Lecturer in Medieval History and Director of the Centre for the Study of Religion and Conflict at Nottingham Trent UniversityKatherine Lewis Senior Lecturer in History at the University of Huddersfieldand Danielle Park Visiting Lecturer at Royal Holloway, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the 1691 peace treaty that ended the Williamite War in Ireland, between supporters of the deposed King James II and the forces of William III and his allies. It followed the battles at Aughrim and the Boyne and sieges at Limerick, and led to the disbanding of the Jacobite army in Ireland, with troops free to follow James to France for his Irish Brigade. The Catholic landed gentry were guaranteed rights on condition of swearing loyalty to William and Mary yet, while some Protestants thought the terms too lenient, it was said the victors broke those terms before the ink was dry.The image above is from British Battles on Land and Sea, Vol. I, by James Grant, 1880, and is meant to show Irish troops leaving Limerick as part of The Flight of the Wild Geese - a term used for soldiers joining continental European armies from C16th-C18th.With Jane Ohlmeyer Chair of the Irish Research Council and Erasmus Smith’s Professor of Modern History at Trinity College DublinDr Clare Jackson Senior Tutor, Trinity Hall, and Faculty of History, University of Cambridgeand Thomas O'Connor Professor of History at Maynooth UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss how, in September 1812, Napoleon captured Moscow and waited a month for the Russians to meet him, to surrender and why, to his dismay, no-one came. Soon his triumph was revealed as a great defeat; winter was coming, supplies were low; he ordered his Grande Armée of six hundred thousand to retreat and, by the time he crossed back over the border, desertion, disease, capture, Cossacks and cold had reduced that to twenty thousand. Napoleon had shown his weakness; his Prussian allies changed sides and, within eighteen months they, the Russians and Austrians had captured Paris and the Emperor was exiled to Elba.WithJanet Hartley Professor Emeritus of International History, LSEMichael Rowe Reader in European History, King’s College LondonAndMichael Rapport Reader in Modern European History, University of GlasgowProducer: Simon Tillotson

Melvyn Bragg and guests discuss the people, plants and animals once living on land now under the North Sea, now called Doggerland after Dogger Bank, inhabited up to c7000BC or roughly 3000 years before the beginnings of Stonehenge. There are traces of this landscape at low tide, such as the tree stumps at Redcar (above); yet more is being learned from diving and seismic surveys which are building a picture of an ideal environment for humans to hunt and gather, with rivers and wooded hills. Rising seas submerged this land as glaciers melted, and the people and animals who lived there moved to higher ground, with the coasts of modern-day Britain on one side and Denmark, Germany, The Netherlands, Belgium and France on the other.With Vince Gaffney Anniversary Professor of Landscape Archaeology at the University of BradfordCarol Cotterill Marine Geoscientist at the British Geological SurveyAndRachel Bynoe Lecturer in Archaeology at the University of SouthamptonProducer: Simon Tillotson

Melvyn Bragg and guests discuss why Athenians decided to send a fast ship to Lesbos in 427BC, rowing through the night to catch one they sent the day before. That earlier ship had instructions to kill all adult men in Mytilene, after their unsuccessul revolt against Athens, as a warning to others. The later ship had orders to save them, as news of their killing would make others fight to the death rather than surrender. Thucydides retells this in his History of the Peloponnesian War as an example of Athenian democracy in action, emphasising the right of Athenians to change their minds in their own interests, even when a demagogue argued they were bound by their first decision.

Melvyn Bragg and guests discuss how the people of Cusco, in modern Peru, established an empire along the Andes down to the Pacific under their supreme leader Pachacuti. Before him, their control grew slowly from C13th and was at its peak after him when Pizarro arrived with his Conquistadors and captured their empire for Spain in 1533. The image, above, is of Machu Picchu which was built for emperor Pachacuti as an estate in C15th.

Melvyn Bragg and guests discuss the impact of Grant's presidency on Americans in the years after the Civil War in which he, with Lincoln, had led the Union Army to victory. His predecessor, Andrew Johnson, was prepared to let the Southern States decide for themselves which rights to allow freed slaves; Grant supported equal rights, and he used troops and Enforcement Acts to defeat the Ku klux Klan which was violently suppressing African Americans. In later years Grant was remembered mainly for the corruption scandals under his terms of office, and for his failure to support or protect Native Americans, but in more recent decades his support for reconstruction has prompted a reassessement.WithErik Mathisen Lecturer in US History at the University of KentSusan-Mary Grant Professor of American History at Newcastle UniversityandRobert Cook Professor of American History at the University of SussexProducer: Simon Tillotson

Melvyn Bragg and guests discuss the most destructive riots in London's history, which reached their peak on 7th June 1780 as troops fired on the crowd outside the Bank of England. The leader was Lord George Gordon, head of the Protestant Association, who objected to the relaxing of laws against Catholics. At first the protest outside Parliament was peaceful but, when Gordon's petition failed to persuade the Commons, rioting continued for days until the military started to shoot suspects in the street. It came as Britain was losing the war to hold on to colonies in North America.The image above shows a crowd setting fire to Newgate Prison and freeing prisoners by the authority of 'His Majesty, King Mob.'WithIan Haywood Professor of English at the University of RoehamptonCatriona Kennedy Senior Lecturer in Modern British and Irish History and Director of the Centre for Eighteenth Century Studies at the University of Yorkand Mark Knights Professor of History at the University of WarwickProducer: Simon Tillotson

Melvyn Bragg and guests discuss the life of Nero (37-68 AD) who became Emperor at the age of 16. At first he was largely praised for his generosity yet became known for his debauched lifestyle, with allegations he started the Fire of Rome, watching the flames as he played the lyre. Christians saw him as their persecutor, an anti-Christ, and the number of the Beast in the Book of Revelation was thought to indicate Nero. He had confidence in his own artistry, took up acting (which then had a very low status) and, as revolts in the empire grew, killed himself after the Senate condemned him to die as a slave, on a cross.

Melvyn Bragg and guests discuss why the potato crop failures in the 1840s had such a catastrophic impact in Ireland. It is estimated that one million people died from disease or starvation after the blight and another two million left the country within the decade. There had been famines before, but not on this scale. What was it about the laws, attitudes and responses that made this one so devastating?The image above is from The Illustrated London News, Dec. 29, 1849, showing a scalp or shelter, "a hole, surrounded by pools, and three sides of the scalp were dripping with water, which ran in small streams over the floor and out by the entrance. The poor inhabitants said they would be thankful if the landlord would leave them there, and the Almighty would spare their lives. Its principal tenant is Margaret Vaughan."With Cormac O'Grada Professor Emeritus in the School of Economics at University College DublinNiamh Gallagher University Lecturer in Modern British and Irish History at the University of CambridgeAnd Enda Delaney Professor of Modern History and School Director of Research at the University of EdinburghProducer: Simon Tillotson
