Sarah Dunant presents a monthly dive into stories from the past that might help us make sense of today. This month, as Theresa May‘s Brexit negotiations approach crunch point, Sarah examines promises throughout history, how they bound rulers and their people, and the bitter consequences when they were broken.

From the ambitious pledges that return to haunt Ethelred the Unready in the 10th century, to the trust-based oaths sworn by Swedish monarchs in front of their subjects, Sarah traces the litany of promises made through the centuries and exposes the paradoxes and tensions that plague our leaders today.

And, as we consider a political environment charged with the rhetoric of division, disappointment and betrayal, Sarah examines the ultimate moment of broken promises - the execution of Charles I, and the lasting wounds that it inflicted on a nation.

Sarah's guests are Dr Levi Roach of the University of Exeter, Dr Sari Nauman of the University of Gothenburg, Professor Jeremy Black of the University of Exeter, and Dr Clare Jackson of the University of Cambridge.
