Two and a half years. 50 episodes. 100+ hours. When we set out to cover World War I back in September 2022, after our Scramble for Africa and our Civilizations (1400-1900) series, we had a plan for how we were going to go about it. In this debrief, Dave and I talk about what we were able to do better and worse by using this format compared to when Dave taught it (and I studied it) in high school and when we both studied it in university. As well as some reflections on what stood out from the history, the idea of WWI as an inflection point in history, and previewing our next three series: Interwar, World War II, and Decolonization.
