- Historiography of the causes of World War I Historians writing about the origins of World War I have differed over the relative emphasis they place upon the factors involved. Changes in historical arguments over time are in part related to the delayed availability of classified historical archives.

What is the Best Counterfactual for the Long Ninteenth Century?
From the WST perspective a more interesting counterfactual is "What If WWI, the Great Depression and WWII had never happened". What would the history of Long Twentieth Century have been?
If we have systems models of the major countries in both the 19th and 20th Centuries, we can forecast the 19th Century models into the 20th Century to create an alternative history where WWI, the Great Depression and WWII never happened. When then compare the actual paths of the comparable 20th Century models to see what was actually different.
One possible problem is that the data for the 19th Century, the War and Inter-War Periods are not great for most countries in the World-System. However, what we can do is focus on the estimated Systems Models which do show variability across the major countries over the time period (0-2000+, see examples here).
In future posts, I will start with the World System (WL19 and WE20) and then go on to the other major countries in the Long Nineteenth and Twentieth Centuries (Germany, the UK, France, the US, Italy, Japan, Russia, etc.).
I have already started with some countries, for example France as an example (here). From the FRL19 model, it turns out that the Great Depression and possibly the collapse during WWI can be predicted in France from 19th Century data. The same is not the case for the DEL19D Model (Pasdirtz, 1981).

World-System French Counterfactual (1800-1950) No WWI, Great Depression or WWII
Dec 24, 2025. The New York Times is reporting (here) that "for the second consecutive year ...[France has failed]... to agree to a new national budget by the end of the legislative calendar." It is difficult to understand what is going on in France without some historical background, specifically how France responded to World War I and the Great Depression. ChatGPT reports that

Did Great Britain Stabilize the World System in the 19th Century?
The role of the British Empire in the 19th Century (map in the Notes) was an important part of the Minsky-Kindleberger Framework for understanding the events of the Early 20th Century.
The Explanation of this book [...Charles Kindleberger (2013) World in Depression, 1929-1939...] is that the 1929 depression was so wide, so deep and so long because the international economic system was rendered unstable by British inability and United States unwillingness to assume responsibility for stabilizing it...(pps. 291-292)
The qualitative Minsky-Kindleberger Framework (M-K) can actually be tested using Systems Theory and I will present some of the results in this post. The M-K Framework is important because it is the only explanation of the Great Depression that looks at the entire World-System.
To test the M-K Framework, I compared the Growth Component (W1) from four different World System models: (1) W19 BAU, Business-As-Usual, no Geopolitical Inputs, estimated from (1800-1900) and then forecast into the 20th Century, (2) W19 UK-Input, Geopolitical Inputs from the "declining" UK Hegemonic Leader (3) WE20 BAU, estimated from 1900-1950, and (4) WE20 RU-Input, input from the RU20 model.**
The outputs from the models are graphed at the beginning of this post. Both the W19 BAU and the W19 UK-Input models produce collapse, supporting the M-K Framework. The WE20 models produce steady states around 1950. The WE20 BAU model peaks after 1950 and the WE20 RU-Input model peaks after the Great Depression, and then stabilizes around 1950.
