Nationalism: everything you wanted to know

As the threat of war began to loom in the 1930s, an elaborate system of fortifications sprung up in northeastern France. Known as the Maginot line, this string of defences was designed to protect the nation in the event of an invasion by Nazi Germany. So, when Hitler's forces did invade, how much blame should the Maginot Line shoulder for the fall of France in double-quick time? That's a question that's troubled historians ever since the traumatic events of 1940. In conversation with Spencer Mizen, Kevin Passmore explores why the line has become a symbol of a nation's collective failure to face the challenges of the modern world (Ad) Kevin Passmore is the author of The Maginot Line: A New History (Yale).

What if the 'fall' of Rome wasn’t a collapse, but a rebrand? In this episode, Alice Roberts delves into the dramatic transformation of the Roman world and the rise of Christianity, from cliffside burials in Wales to imperial politics in Constantinople. Speaking to Danny Bird, she reveals how early Christianity wasn’t a grassroots movement of the poor, but a strategic shift embraced by elites, bishops and emperors.

In 2010, the world was stunned when the United States exposed a covert Russian spy network operating on its soil. Seemingly all-American families living in white-picket-fenced suburbia were in fact deep undercover Russian agents. Many had been living under assumed identities for decades, lying even to their own children. In this episode, journalist Shaun Walker speaks to Danny Bird about Moscow’s longlasting ‘illegals’ programme – perhaps the most audacious chapter in the history of espionage. He reveals how the roots of the operation reached back more than a century to before the Bolshevik Revolution; how the Soviet Union deployed it against supposedly ‘friendly’ states; and how today’s Russia reveres these spies as patriotic heroes.

Edward the Confessor, England’s penultimate Anglo-Saxon king, has long been remembered as a saintly, pious monarch – but was he really the weak ruler whose indecision paved the way for the Norman Conquest that some historical sources would have us think? And if not, how should we understand him? Emily Briffett spoke to historian Tom Licence to explore the life of this medieval monarch – from his early years in exile and his ambitions for the crown to the subsequent political challenges he faced that ultimately shaped the fate of England.

Histories of British involvement in the Caribbean tend to focus mainly on the period of plantation slavery but, in her new book Empire Without End, Imaobong Umoren argues that we need to take a broader view. It's only by taking the story back to the 16th century and forward until the present, she contends, that we can fully understand the intertwining themes of colonialism and racism in the region – and see how they connect to events in Britain. In this episode, Imaobong explores these ideas in conversation with Rob Attar. (Ad) Imaobong Umoren is the author of Empire Without End: A New History of Britain and the Caribbean (Fern Press, 2025).

In this Everything You Wanted To Know episode, Danny Bird puts these questions and others submitted by our listeners to John Hutchinson.
