This is the first episode in a two-part series on the brutal, three-decade-long civil war that tore England in two. Today, we explore the complex allegiances, rivalries, and personalities that made it all happen before hearing about the first bloody battles between the houses of York and Lancaster.

For this, we're joined by Matt Lewis, historian, author and host of our sister podcast, Gone Medieval.

Produced by James Hickmann and edited by Dougal Patmore.
