Few parties in history can match the Georgian 'Masquerade'. And among Georgian masquerades the one given by the King of Denmark in London in 1768 was particularly enchanting. It brought those of the greatest means and highest rank together in London theatre that was filled with artful costumes and glittering jewels.

This week's guest, Meghan Kobza, tells us all about the Georgian masquerade – who started it, where did it come from, how much did it cost to get in – and she takes us inside the theatre in 1768. One character who catches her eye is the unfortunate Agneta Yorke whose night turns out to be a comedy of errors.

This week the Cambridge professor Rory Naismith takes us back to the eighth century to glimpse what we can of Offa King of the Mercians. Offa was a mighty figure in this early moment in the history of Britain and he is remembered chiefly for the extraordinary earthwork – Offa's Dyke.

But what more can be said about Offa's life? In this episode Naismith explains that he was a ruler of considerable gifts whose reputation stretched far beyond his considerable kingdom. He corresponded with Charlemagne and was connected with the Islamic World and, when he died, he left a great void behind.

The Netherlands is a small nation with a big history. But in the 1940s it suffered a series of disastrous events. First came the invasion of the Nazis in 1940. Then the very next year the Japanese attacked their old empire in the east. The horrors of World War Two were then followed by the Indonesian National Revolution and, by 1950, the Dutch were a 'pocket superpower' no longer.

In this episode the journalist and hiker Nicholas Walton takes us back to examine this challenging moment in Dutch history. It was a time of reckoning with the past but also a moment of bright new beginnings.

Nicholas Walton is the author of Orange Sky, Rising Water: The Remarkable Past and Uncertain Future of the Netherlands.

The late eighteenth century history was a time in Europe when a brilliant old world collapsed and raucous new one rose to replace it. In this episode the biographer Veronica Buckley explains how the Hapsburgs, one of the great European families, responded to this revolutionary change.

It was a stern challenge but inspired by one of the great matriarchs in European history, Empress Maria Theresia, her son Emperor Joseph II, his successor Leopold and their sister, Marie Antoinette, reacted as best they could in that perilous year, 1790.

Most people know Daniel Defoe as one of the great writers in the history of English literature. But the author of Robinson Crusoe was much more than that. A rabble rousing pamphleteer and erratic entrepreneur, in the early years of the eighteenth century Defoe also became an undercover political operative.

Defoe's career as a spy intersected with a huge moment in British history when the Act of Union between England and Scotland was being planned in 1706. Today's guest, the historian Marc Mierowsky, revisits this time in today's episode – analysing a series of events that were crucial to the genesis of Great Britain 

Marc Mierowsky is the author of A Spy Amongst Us. 

Scene One: July 1706. The Cockpit in Whitehall. The Scottish and the English commissioners finally settle on the terms of the treaty for the Act of Union.

Scene Two: 23 October 1706. Edinburgh. The treaty has been sent north - it is being debated in the Scottish parliament -- and a riot breaks out. Defoe is a witness to the disorder.

Scene Three: December 1706. The west of Scotland. Defoe deploys agent John Pierce to infiltrate the Hebronites.

Today’s guest, Sean Cunningham, takes us back to a particularly perilous year in the eventful reign of King Henry VII. He explains that 1497 was a year of brinkmanship, battles, plots and disasters that very nearly resulted in the fall of the House of Tudor.

Sean Cunningham is Head of Collections, Medieval, Early Modern and Legal, at the National Archives in Kew. He is one of the leading authorities on the life and times of Henry VII – the first of the Tudor monarchs.

Often overshadowed by his attention-hogging son (he of the six wives), Henry VII was a formidable operator: wily, quicksilver, determined, restless. He needed all these qualities to survive the multiple threats to his rule.

Sean Cunningham is the author of Henry VII: Treason and Trust.

Scene One: August 1497. King James IV of Scotland challenges the Earl of Surrey to single combat.

Given the scandal surrounding Andrew Mountbatten-Windsor, we thought we'd examine an eerily familiar moment in British history. In January 1809 the Duke of York became the subject of a huge and embarrassing news story. It was a story of sex, power, money and corruption right at the heart of British politics. One of the stars of the affair was a woman of no rank, title or fortune. Her name was Mary Anne Clarke.

Scene One: 27 January 1809. Colonel Wardle stands up in the House of Commons.

Scene Two: 1 February 1809, Mary Anne Clarke gives evidence before the House of Commons.

Scene Three: 20 March 1809, Spencer Percival announces the Duke of York's resignation as Commander in Chief to the House of Commons.

Our guest today is the New York Times bestselling historian Charles King, the author of Every Valley: The Desperate Lives and Troubled Times that Made Handel's Messiah.

The Messiah is one of the best known pieces of all classical music and, as King suggests at the beginning of this conversation, it 'may be the world's greatest monument to the possibility of hope'.

To tell us more about how such an extraordinary piece was written, as well as to take us along to its premiere in Dublin in April 1742, King sat down with us for a travel back through time just the other day.
