In this pod I was joined by two people who have played quite an important part in my life: my mum and dad (known to the rest of the world as Peter Snow and Ann MacMillan). Their latest book is a bold examination of world history, told through 50 of our most important documents. They have been sourced from collections of national archives, museums, libraries, and private collections across the globe. From this selection of 50, I asked for a selection of six to discuss in this episode, telling a story of our political, military, artistic, and scientific challenges and achievements.
