In 1883 a grass-roots political organisation was founded that re-shaped Victorian politics. The Primrose League signed up a million members and an army of Conservative activists who helped win elections by reaching out to new Tory voters in industrial cities and rural shires.

Today another innovative grass-roots organisation is proving influential. Emerging from Jeremy Corbyn's 2015 leadership campaign, Momentum has proved highly effective at winning over new Labour voters, swapping the magic lantern shows and Stately Home fetes of the Primrose League for a cutting edge social media campaign.

Jonathan Freedland and his guests compare electioneering in the nineteenth century and today and explore the often troubled relationship between grass-roots organisations and the parliamentary parties they support . They also ask whether the Conservatives need a latter-day Primrose League to boost their electoral appeal, particularly with younger, urban voters.

Joining Jonathan are Dr Jon Lawrence of the University of Cambridge, James Kanagasooriam of Populus and the journalists Sebastian Payne and Ellie-Mae O'Hagan. Laura Morgan is the reader.

Jonathan Freedland compares cyber-attacks today with the Great Siege of Dover Castle in 1216 during which the French used new offensive techniques to try to seize the English throne.

In 1216, Prince Louis of France's near-successful bid for the English throne climaxed in Dover, where his forces used a multitude of techniques in a major assault on the castle - including digging beneath the castle gate and use of the trebuchet to attempt to breach the walls. Jonathan draws on this medieval example to discuss cyber security in the 21st century context.

Joining Jonathan at Dover Castle are medieval historian Marc Morris; General Sir Richard Barrons, former Commander Joint Forces Command, one of the six Chiefs of Staff leading the UK Armed Forces until April 2016; Kenneth Cukier of The Economist; and Sara Perez, ethical hacker at SensePost. Readings are by Hugh Simon who played MI5 Data Analyst Malcolm Wyn-Jones in the popular BBC TV series Spooks.

Jonathan Freedland takes the Long View of landmark fires exploring the parallels between the tragedies of the Watson Street fire in Glasgow in 1905 and Grenfell Tower.

In the East End of Glasgow in 1905 a 'Model Lodging House' at 39 Watson Street caught fire. It housed 300 poor working men, many of them migrants from Ireland and the Highlands. The lodging house itself was densely populated with men sleeping in wood lined cubicles and with only one exit to the street through a turnstile. The fire spread very rapidly, trapping those who couldn't escape on the upper floors and 39 people were killed.

The tragedy immediately drew public attention to fire and building regulations and the urgent need to improve them and an Inquiry soon followed.

Jonathan is joined by historian of fires and fire services Shane Ewen, BBC London reporter Anna O'Neil, retired fireman Jim Smith, Secretary of the Royal Incorporation of Scottish Architects Neil Baxter and actor Robin Laing to explore the parallels between the Watson Street and the Grenfell Tower tragedies.

As we prepare to leave the EU, Jonathan Freedland compares overseas trade in today's Elizabethan age with that of the sixteenth century. In 1570 Elizabeth I was the subject of a Papal Bull of Excommunication, Theresa May must write a letter to Europe to trigger Article 50. Both documents will have a profound impact on trade.

Elizabeth's response to her European troubles was to forge new trade links with the East, sending merchants to Turkey, Persia and North Africa. Today's trade ministers hope to emulate the achievements of their Tudor counterparts, but how important is trade with Europe to our prosperity and how easy will it be to do new trade deals on more distant shores ?

Taking the Long View of trade, Jonathan is joined by Professor Jerry Brotton of Queen Mary University of London, author of 'This Orient Isle:Elizabethan England and the Islamic World'. Discussing today's export markets are the economists George Magnus, Liam Halligan and Dr Monique Ebell and our actor is Anita Dobson.

Jonathan Freedland compares the current wave of fake news stories, particularly those targeted at Muslims and immigrants in the UK, with the anti-Semitic story of an eight-year-old Christian boy, William of Norwich, who was murdered in woodland outside his native city in 1144. His death was later reported as a Jewish conspiracy and ritual, becoming the founding myth of the so-called 'blood libel'.

Jonathan Freedland compares Donald Trump's proposed border wall with the impenetrable 2500 mile Great Hedge of India constructed in the 1840s to control trade between British India and the Princely States.

The Long View of Brexit, comparing it with the English Reformation. Professor Diarmaid MacCulloch is the lead historian explaining that Henry VIII broke away from the Ecclesiastical control of Rome with the help of his 'fixer' Thomas Cromwell. However, Cromwell's ambitions were driven by his Protestantism whereas Henry was interested in securing his legacy and not making substantial changes to the national religion.

As Hillary Clinton becomes the official Democrat candidate for US President, with aim of becoming the first woman to take that role, Jonathan Freedland takes the long view of pioneering women politicians, examining how Nancy Astor became the first woman to take her seat in the House of Commons - in a constituency previously represented by her husband. Astor faced intense press scrutiny, and a presumption that she should focus on issues such as child welfare - but she also enjoyed the renown of the Astor name.

Military drones today and the Nazi V1 and V2 weapons. With Jonathan Freedland

As pre-season training gets underway and transfer business goes on a-pace Jonathan Freedland takes the Long View of celebrity Football management. The new season will see the clash of several of the world's greatest managers lead by Jose Mourinho of Manchester United and Pep Guardiola of Manchester City.

It was a similar story in Manchester back in the mid 1960s. Matt Busby had been at United since the war building championship winning teams and a formidable reputation. City were languishing in the second division. But with the arrival of Joe Mercer and Malcolm Allison, City found a combination to challenge their Manchester rivals. And it really was a case of the Managers being the all important figures. When England won the world cup in 1966 it was Joe Mercer who'd just lead City to the old 2nd Division championship who was part of the BBC Television World Cup panel, endearing himself to the nation by referring to Pele as Peely.

Jonathan is joined by a former City player Paul Hince, Dr Colin Shindler, a screenwriter, academic and fanatic City fan, Sarah Collins who covers the city's sport for BBC local radio and Paul Gilroy of the League Managers Association. They discuss the then and now and the curious way in which - in these two eras - it was the Managers who were in the limelight. Much has changed, not least in terms of global reach, money and the international flavour of the Premiership, but at heart it's the same - the men on the pitch will be playing, and did play, in the shadow of the Celebrity Managers.
