Melvyn Bragg and his guests discuss the Concordat of Worms. This treaty between the papacy and the Holy Roman Empire, signed in 1122, put an end, at least for a time, to years of power struggle and bloodshed. The wrangling between the German kings and the Church over who had the ultimate authority to elect bishops, use the ceremonial symbols of office in his coronation and even choose the pope himself, was responsible for centuries of discord. The hatred between the two parties reached such a pinnacle that it resulted in the virtual destruction of Rome at the hands of the Normans in 1084.Nearly forty years later Emperor Henry V and Pope Calixtus II came to a compromise; their agreement became known as the Concordat of Worms, named after the town where they met and signed the treaty. The Concordat created a historic distinction between secular power and spiritual authority, and more clearly defined the respective powers of monarchs and the Church. Although in the short term the Concordat failed to prevent further conflict, some historians believe that it paved the way for the modern nation-state.With:Henrietta LeyserEmeritus Fellow of St Peter's College, University of OxfordKate CushingReader in Medieval History at Keele University John Gillingham Emeritus Professor of History at the London School of Economics and Political Science Producer: Natalia Fernandez.

Melvyn Bragg and his guests discuss the revolutionary Jewish leader Judas Maccabeus. Born in the second century BC, Judas led his followers, the Maccabees, in a rebellion against the Seleucid Empire, which was attempting to impose the Greek culture and religion on the Jews. After a succession of battles he succeeded and the Seleucid king granted the Jews religious freedom. But even after that freedom was granted the struggle for political independence continued, and it was not until twenty years after Judas's death that Judaea finally became an independent state. Thanks to an extensive, if often confused, historical record of these events, the story of the Maccabees is well known. Judas Maccabeus has become a celebrated folk hero, and one of his achievements, the restoration and purification of the Temple of Jerusalem after its desecration by the Seleucids, is commemorated every year at the Jewish festival of Hanukkah.With: Helen Bond, Senior Lecturer in the New Testament at Edinburgh University Tessa Rajak, Emeritus Professor of Ancient History at the University of ReadingPhilip Alexander, Emeritus Professor of Jewish Studies at the University of ManchesterProducer: Natalia Fernandez.

Melvyn Bragg and his guests discuss the Japanese belief system Shinto.A religion without gods, scriptures or a founder, Shinto is perhaps better described as a system of belief. Central to it is the idea of kami, spirits or deities associated with places, people and things. Shinto shrines are some of the most prominent features of the landscape in Japan, where over 100 million people - most of the population - count themselves as adherents.Since its emergence as a distinct religion many centuries ago, Shinto has happily coexisted with Buddhism and other religions; in fact, adherents often practise both simultaneously. Although it has changed considerably in the face of political upheaval and international conflict, it remains one of the most significant influences on Japanese culture.With:Martin PalmerDirector of the International Consultancy on Religion, Education, and CultureRichard Bowring Professor of Japanese Studies at the University of CambridgeLucia DolceSenior Lecturer in Japanese Religion and Japanese at the School of Oriental and African Studies, University of London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss John Wyclif and the Lollards.John Wyclif was a medieval philosopher and theologian who in the fourteenth century instigated the first complete English translation of the Bible. One of the most important thinkers of the Middle Ages, he also led a movement of opposition to the Roman Church and its institutions which has come to be seen as a precursor to the Reformation. Wyclif disputed some of the key teachings of the Church, including the doctrine of transubstantiation. His followers, the Lollards, were later seen as dangerous heretics, and in the fifteenth century many of them were burnt at the stake. Today Lollardy is seen as the first significant movement of dissent against the Church in England.With:Sir Anthony KennyPhilosopher and former Master of Balliol College, OxfordAnne HudsonEmeritus Professor of Medieval English at the University of OxfordRob LuttonLecturer in Medieval History at the University of NottinghamProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the origins and early development of Islamic law. The legal code of Islam is known as Sharia, an Arabic word meaning "the way". Its sources include the Islamic holy book the Qur'an, the words and actions of the Prophet Muhammad, and the opinions of legal scholars. In the 7th century, Sharia started to replace the tribal laws of pre-Islamic Arabia; over the next three hundred years it underwent considerable evolution as Islam spread. By 900 a body of religious and legal scholarship recognisable as classical Sharia had emerged.With:Hugh KennedyProfessor of Arabic in the School of Oriental and African Studies at the University of LondonRobert GleaveProfessor of Arabic Studies at the University of ExeterMona SiddiquiProfessor of Islamic Studies at the University of GlasgowProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Pelagian Controversy.In the late 4th century a British monk, Pelagius, travelled to Rome, where he became a theologian and teacher, revered for his learning and ascetic lifestyle. But he soon aroused the ire of some of the Church's leading figures, preaching a Christian doctrine which many regarded as heretical. Pelagius believed that mankind was not inherently depraved, and disputed the necessity of original sin. His opinions were highly controversial and led to fierce division. Pelagius's most prominent opponent was the African bishop St Augustine of Hippo. Their dispute resulted in the persecution and eventual condemnation of Pelagius and his followers, and was to be of long-lasting significance to the future of the Church.With:Martin PalmerDirector of the International Consultancy on Religion, Education, and CultureCaroline HumfressReader in History at Birkbeck College, University of LondonJohn MilbankProfessor in Religion, Politics and Ethics and the Director of the Centre for Theology and Philosophy at Nottingham UniversityProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Bhagavad Gita.The Bhagavad Gita, a 700-verse section of the Sanskrit epic the Mahabharata, is one of the most revered texts of Hinduism. Written in around 200 BC, it narrates a conversation between Krishna, an incarnation of the deity, and the Pandava prince Arjuna. It has been described as a concise summary of Hindu theology, a short work which offers advice on how to live one's life.The Gita is also a philosophical work of great richness and influence. First translated into English in the 18th century, it was quickly taken up in the West. Its many admirers have included Mahatma Gandhi, whose passion for the work is one reason that the Bhagavad Gita became a key text for followers of the Indian Independence movement in the first half of the twentieth century.With:Chakravarthi Ram-PrasadProfessor of Comparative Religion and Philosophy at Lancaster UniversityJulius LipnerProfessor of Hinduism and the Comparative Study of Religion and Fellow of Clare Hall at the University of CambridgeJessica FrazierResearch Fellow at the Oxford Centre for Hindu Studies and Lecturer in Religious Studies at Regent's College, LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the work and influence of Maimonides.Widely regarded as the greatest Jewish philosopher of the medieval period, Maimonides was also a physician and rabbinical authority. Also known as Rambam, his writings include a 14-volume work on Jewish law, the Mishneh Torah, which is still widely used today, and the Guide for the Perplexed, a central work of medieval philosophy. Although undoubtedly a titan of Jewish intellectual history, Maimonides was also profoundly influenced by the Islamic world. He exerted a strong influence on later Islamic philosophy, as well as on thinkers ranging from Thomas Aquinas to Leibniz and Newton.With:John HaldaneProfessor of Philosophy at the University of St AndrewsSarah StroumsaAlice and Jack Ormut Professor of Arabic Studies and currently Rector at the Hebrew University of JerusalemPeter AdamsonProfessor of Ancient and Medieval Philosophy at King's College London.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss Daoism. An ancient Chinese tradition of philosophy and religious belief, Daoism first appeared more than two thousand years ago. For centuries it was the most popular religion in China; in the West its religious aspects are not as well known as its practices, which include meditation and Feng Shui, and for its most celebrated text, the Daodejing.The central aim in Daoism is to follow the 'Dao', a word which roughly translates as 'The Way'. Daoists believe in following life in its natural flow, what they refer to as an 'effortless action'. This transcendence can be linked to Buddhism, the Indian religion that came to China in the 2nd century BC and influenced Daoism - an exchange which went both ways. Daoism is closely related to, but has also at times conflicted with, the religion of the Chinese Imperial court, Confucianism. The spirit world is of great significance in Daoism, and its hierarchy and power often take precedence over events and people in real life. But how did this ancient and complex religion come to be so influential?With:Tim Barrett Professor of East Asian History at the School of Oriental and African Studies, University of LondonMartin PalmerDirector of the International Consultancy on Religion, Education and CultureHilde De WeerdtFellow and Tutor in Chinese History at Pembroke College, University of Oxford Producer: Natalia Fernandez.

Melvyn Bragg and his guests discuss John Foxe and his book Actes and Monuments, better known today as Foxe's Book of Martyrs. Born in 1517, John Foxe was an early Protestant who was forced to flee the persecutions which ensued when the Catholic Mary came to the English throne in 1553. He was a horrified observer on the Continent as more than three hundred of his countrymen were burnt at the stake. In exile he began work on a substantial work of scholarship, bringing together eyewitness accounts of these horrifying deaths.First published in 1563, Foxe's Book of Martyrs was one of the most elaborate early books produced, and thanks to vivid woodcut illustrations reached an audience far beyond the literate elite. Its stories of Protestant martyrdom became powerful Church propaganda in the late sixteenth century and were used by those who wished to banish Catholicism from England permanently. But despite its use as an instrument of religious factionalism, Foxe's work remains one of the key and most read books of the early modern period.
