Misha Glenny and guests discuss the exchange of cultures and biology across the Atlantic and Pacific after 1492. That was when Columbus reached the Bahamas, a time when Europe had no potatoes, tomatoes, sunflowers or, arguably, syphilis in its most virulent form; the Americas had no cattle, bananas, sugar cane or smallpox. The lists of what was then exchanged are long and as these flora, fauna and diseases moved between continents, their impact ranged from transformation to devastation. In parts of the Americas, European viruses helped kill over 90 percent of the population. In parts of Europe, Africa and Asia populations boomed on the new American foods. Sheep from Europe grazed fertile land into deserts in some parts of the Americas, while the lowered populations in others led to local reforestation which, arguably, is linked to a particularly cold period in the Little Ice Age.

Misha Glenny and guests discuss the short life and lasting works of Keats (1795-1821), who in one year wrote some of the most loved poems in English. Among these are Ode to a Nightingale, Ode on a Grecian Urn and Ode on Melancholy. That most productive year began in autumn 1818, when Keats had been stung by some reviews labelling him an uncouth Cockney who should go back to his former work as an apothecary, work he had left for poetry only two years before with the encouragement of enthusiastic friends. Just over two years later, Keats was dead in Rome from tuberculosis, before his work found fame, though some who knew him, including Shelley, believed his true killer was the critics.

Misha Glenny and guests discuss the laws that Hammurabi (c1810 - c1750 BC), King of Babylon, had carved into a black basalt pillar in present day Iraq and which, since its rediscovery in 1901 in present day Iran, has affirmed Hammurabi's reputation as one of the first great lawmakers. Visitors to the Louvre in Paris can see it on display with almost 300 rules in cuneiform, covering anything from ‘an eye for an eye’ to how to handle murder, divorce, witchcraft, false accusations and more. The Code of Hammurabi, as it became known, made such an impression in Mesopotamia that it was copied and shared for a millennium after his death and, since its reemergence, Hammurabi and his Code have been commemorated in the US Capitol and the International Court of Justice.

Misha Glenny and guests discuss one of the most successful of Shakespeare's plays in his own time. Written with no Part 2 in mind as 'Henry the Fourth', the play explores ideas about who can be a legitimate ruler and why, and how anyone can rightly succeed to the throne. This was an especially pressing question for his Tudor audience as Elizabeth I had named no successor. Playwrights, banned from openly discussing the jeopardy her subjects faced, turned to these themes of power, legitimacy and succession in distant and recent history. When Shakespeare combined this relevance with the vivid characters of Falstaff, Hotspur and Hal and with the tensions between noble fathers and sons, he had a play that fascinated well into the Jacobean era and has been revived throughout the centuries.

Misha Glenny and guests discuss the countless venues across the Roman Empire which for over five hundred years drew the biggest crowds both in the Republic and under the Emperors. The shows there delighted the masses who knew, no matter how low their place in society, they were much better off than the gladiators about to fight or the beasts to be slaughtered. Some of the Roman elites were disgusted, seeing this popular entertainment as morally corrupting and un-Roman. Moral degradation was a less immediate concern though than the overspill of violence. There was a constant threat of gladiators being used as a private army and while those of the elite wealthy enough to stage the shows hoped to win great prestige, they risked disappointing a crowd which could quickly become a mob and turn on them.

Misha Glenny and guests discuss one of the wonders of the natural world. In 1875 in the western Pacific, the crew of HMS Challenger discovered the Mariana Trench which turned out to be deeper than Everest is high, by two kilometres. Trenches like Mariana form when one tectonic plate slips under another and heads down and there are around fifty of them globally. While at one time some thought it was too dark and deep for life there and others wildly imagined monsters, the truth has turned out to be much more surprising.

Journalist, author and historian Misha Glenny presents his first edition of In Our Time, succeeding Melvyn Bragg who retired from this role last summer. Misha and his guests discuss the landmark work On Liberty by John Stuart Mill, published in 1859 and the increasing recognition for his wife Harriet Taylor Mill's contribution. The subject matter of the essay is ‘civil or social liberty: the nature and limits of the power which can be legitimately exercised by society over the individual’ and it argues that the sole end for which mankind may interfere with the liberty of action of anyone is self-protection and even then only to prevent harm to others. This essay became enormously popular and a foundational text for liberalism.

Misha Glenny introduces himself to you ahead of his first episode on 15th January, answering some questions from producer Simon Tillotson and sharing what's coming up in the first few weeks.

In Our Time is a BBC Studios production

Before Misha Glenny's first edition on 15th January, BBC Radio 4's flagship news programme Today has brought Melvyn Bragg and Misha Glenny together so they can share their ideas about In Our Time's success and discuss what, if anything, will change with Misha. While Justin Webb chaired this discussion, here you will hear Melvyn introduce it and at the end he has a message for Misha and for listeners around the world.

This is a longer version of the discussion broadcast on Today on Radio 4 on Christmas Eve 2025 which was produced by Jade Bogart-Preleur, when Melvyn Bragg was the guest editor.

Melvyn Bragg and guests discuss the idea that Civility, in one of its meanings, is among the most valuable social virtues: the skill to discuss topics that really matter to you, with someone who disagrees and yet somehow still get along. In another of its meanings, when Civility describes the limits of behaviour that is acceptable, the idea can reflect society at its worst: when only those deemed 'civil enough' are allowed their rights, their equality and even their humanity. Between these extremes, Civility is a slippery idea that has fascinated philosophers especially since the Reformation, when competing ideas on how to gain salvation seemed to make it impossible to disagree and remain civil.
