The interwar period (1919-1939) is critical because it shaped the political, economic, and social conditions that led to the Second World War. It includes key events like the rise of fascism, the Great Depression, and the failure of the League of Nations, all of which influenced the decisions and actions of nations and leaders, ultimately setting the stage for global conflict.
The podcast focuses on: 1) Were there opportunities between 1919 and 1939 to avoid or reduce the likelihood of war? 2) Were there events that nearly triggered a global conflict before 1939, and why were they avoided? 3) How did leaders and citizens perceive the events of the interwar period, and did they see war as inevitable?
The League of Nations was created to promote international cooperation and prevent future conflicts. While it ultimately failed to stop the Second World War, it provided a framework for international diplomacy and conflict resolution, and its successes and failures offer important lessons about the challenges of maintaining global peace.
The Great Depression caused severe economic downturns worldwide, leading to political instability and drastic policy changes. In Germany, it exacerbated existing tensions and contributed to the rise of the Nazi Party. Economic struggles also pushed many nations toward isolationism and nationalism, further destabilizing international relations.
The Italo-Ethiopian War (1934) marked a significant escalation in European tensions, as Italy's aggressive expansion in Africa brought Europe closer to war than it had been since 1919. It highlighted the failure of international institutions like the League of Nations to prevent aggression and set a precedent for further conflicts.
Judging decisions based on the information available at the time avoids the pitfalls of hindsight bias. It allows for a more accurate understanding of why certain choices were made, recognizing that outcomes are not always predictable and that good decisions can sometimes lead to bad results, and vice versa.
Key conflicts included the Italo-Ethiopian War (1934) and the Spanish Civil War (1936-1939). These conflicts saw the involvement of multiple nations and ideologies, bringing Europe closer to a larger war. Additionally, the Second Sino-Japanese War (1937) in Asia further destabilized global relations.

Hello everyone and welcome to History of the Second World War Episode 1, an introduction to Season 1 of the show, which I am calling, rather ominously, Return of the Shadow.
This week, I would like to thank everybody who is currently supporting the podcast on Patreon. There are too many of you to thank individually, but just know that I thank you. As part of my thanks for their support, I provide patron-exclusive content once a month, like the episode that released this month that discusses the evolution of the Royal Navy in the immediate aftermath of the First World War.
If that sounds interesting to you, head on over to historyofthesecondworldwar.com slash members to find out more information. This episode is all about the first season of the podcast, which will cover the interwar period. At the end of this episode, I hope you understand why the interwar period is so important, and why the podcast is spending so much time discussing the events before September 1st, 1939.
The Second World War is in many respects the event of the 20th century. It was influenced by earlier events and it would cast its shadow over the following decades. Fighting would stretch around the globe and few areas would escape its effects. The human cost of the war is almost incalculable.
Even if you could arrive at a final figure for military personnel killed or wounded, of civilians killed or injured, that number just barely scratches the surface of the pain and suffering caused by the war. The mental, emotional, and physical oppression and persecution perpetrated by foreign invaders and local despots. The deprivation and destitution caused by the demands of fighting a total war with its resulting poverty and starvation.
the grief caused by the loss of spouses siblings parents and children all of these are the legacy of the war even if at times it is plastered over by patriotism and propaganda
That's how we end up here, over a hundred years after the war that was supposed to end all wars, but which was destined to be known not as the World War, but as the First World War. If there is an event titled the First World War, then there must be a second. They would both be wars that would begin with fighting in the same geographical regions, between some of the same nations, with armies led by many of the same individuals who had participated in the first.
These facts bring us to the question of the interwar period. How was it possible that a generation that had lived through and participated in the greatest war in human history would start another, an even more devastating global conflict just 20 years later?
The events of the interwar period are often neglected, and if they are given any of the spotlight, they are often treated not as discrete events, but as inevitable stepping stones on the path to war. The story of events generally begins with Hitler coming to power in 1933, then rapidly moving on to the Munich Agreement, and then to September 1st, 1939, all with the speed of the mythical Blitzkrieg.
If we're going to try and take a different approach, it cannot fully divorce itself from the fact that a European and later global war would begin in 1939. To try and do so would just be folly. Instead, we will try to avoid answering the question "Why did the Second World War begin?" and instead focus on three more nuanced questions which are perhaps not quite so leading in nature.
The first is, were there any points during the period between 1919 and 1939 that provided an opportunity for the leaders around the world to avoid, postpone, or reduce the likelihood of a future conflict? Second, were there any events between 1939 that brought the world close to a global conflict? And if so, how was that avoided? And why were similar strategies unsuccessful in 1939?
Third, and finally, how did the people, both leaders and average citizens, view the events that occurred during this period? Did they see them as seemingly unavoidable sliding towards a conflict or as something else? The third question may be the most important, specifically because of how the study and discussion of history before events like the Second World War should be treated.
It's very easy to fall into the trap of criticizing or praising decisions based on the outcome of history. This results-based analysis is very easy to do, but it can be a disservice to the actual events that occurred. It can also cause incorrect conclusions to be made about events and decisions that were made at the time.
Instead of judging decisions based on the outcome, an outcome that those making the decision did not of course know, we should instead seek to judge decisions based on the information available at the time. It's only in this way that the correctness or incorrectness of a decision can be determined.
These outcomes do not always alter the correctness of the original decision. But not all decisions that result in bad outcomes were bad decisions. And not all decisions that result in good outcomes were good decisions. This is due to one of the great tragedies of life, and it's just as true in war as in any other theater. People can make all the right decisions and still fail. And you can make many incorrect decisions and still succeed.
This ties into a very easy trap to fall into when looking at the interwar period, which is judging decisions based on the fact that we know exactly when the war begins.
Nobody around the world knew when, where, or how the war would begin until just months before it happened. Even the Germans, who would be the ones to invade Poland, did not know that they would be launching an operation in 1939 until just months beforehand. During the interwar years, people did not even know that a war would happen at all, and this altered perceptions of what should be done.
The uncertainty of possible future war also interacted with political movements all around the world to change how governments and nations reacted to the actions of other states, both towards and away from conflict. All of these considerations and complications will be a running theme for the interwar period, and I will refer back to the question of how we judge decisions during this period of history several times.
The other two questions, could the war have been prevented, and was it possible that it could have started earlier, will also be a topic we will refer back to. We will spend the better part of the next 50 episodes trying to answer them. The next two episodes will be a brief overview of the First World War and then the Paris Peace Conference. These events would be critical to the worldviews of many world leaders and citizens in the 1920s and 30s, and they would cast a long shadow.
For many groups, the most important outcome of the war and the treaty was the creation of the League of Nations. It was an organization designed to foster and promote international cooperation. It was supposed to prevent future conflicts, to provide an alternative means for nations to adjudicate their differences. It, of course, failed, and we will discuss why and how it failed, and also how, in some ways, it succeeded.
We will then turn our eyes to Italy to discuss the rise to power of Benito Mussolini and the creation of the Italian fascist state. Mussolini would not be the first fascist, but he would be the first to find his way into a position to lead a nation. We will then discuss the New York stock market crash of 1929 and the resulting economic downturn experienced around the world, known as the Great Depression, the Great Slump, and by many other names.
These economic problems would put many nations, already under the strain of events of the 1920s, into a serious crisis. For some, it would cause drastic political changes. For others, it would force drastic economic policy alterations.
One country that would see both was Germany, where the leaders of the German Republic created after the First World War had always been somewhat precariously perched at the top of the German nation. After German political changes, there were many topics and trends that would run throughout the 1930s in many nations that we will need to discuss.
These include the discussions and decisions made around disarmament, arms control and rearmament, and then peace movements around Europe, and the slide of many nations into economic isolation and political nationalism.
All of these topics will then set the stage for conflict. The first conflict that we will discuss will be the Italo-Ethiopian War that would begin in 1934. The violent expansion of Italian influence in Africa would bring Europe remarkably close to war, far closer than it had been at any point since 1919.
This would just be the first conflict in Europe during the 1930s that would cause international tensions to greatly increase, with the second being the Spanish Civil War, which would see the various political ideologies of the Western world all come into direct conflict in Spain. The increasing interest and interventions of nations throughout Europe would also introduce a very serious threat of the Spanish conflict spilling out into a larger war,
We will then close out the first season of episodes by turning our eyes away from Europe and towards Asia. Tension in China had been ongoing for many years, and these tensions would occasionally flare up in violence. This tension and the continual push by the Japanese political and military leaders to expand their influence and control in China would eventually lead to the Second Sino-Japanese War, which would see a new level of violence erupt in Shanghai in 1937.
I have set up a website for the podcast over at historyofthesecondworldwar.com, and on that website you can find links to all of the various social media sites where the podcast has a presence. You can find a link to the Patreon page if you'd like to support the show. You can also find a rough podcast roadmap that lays out the basic structure of future content.
I've also posted a full list of sources used for the podcast, which will continue to grow in the coming months and years. There are also episode notes for every episode, including the sources used for the episode and a rough transcript. I hope you have enjoyed this episode, and I hope you will join me for the next one, in which we will discuss, in the absolute briefest way I know how, the history of the Great War.
