The End of Collective Security
- As we have seen in previous sections, the 1930s was a period of heavy economic and political crisis, impacting both on the domestic and foreign policies of nations.
- The idea of the end of collective security shows how WW2 was in a way allowed by the lack of commitment of countries to preserve peace.
- "Collective security" in the 1930s referred to the idea that countries would act together to prevent aggression and maintain peace, typically through international cooperation, especially within the framework of the League of Nations.
- It was an ideal that emerged after the traumatic consequences of WW1, but it proved to be no more than that.
Why did collective security fail?
1. The Impact of the Great Depression
- The Great Depression brought high levels of unemployment and very low productivity.
- The political translation this had was that peoples in different parts of the world grew disillusioned by democracy and liberal capitalism.
- Partly as a consequence of the Great Depression, Hitler came to power in Germany in 1933 with an explicit aim of disrupting international order and rejecting treaties.
- The US had not joined the League of Nations in 1920, and the Depression only deepened its political isolationism.
- Apart from recalling loans, the Americans raised tariffs and established protectionist measures.
- This suggested that the US would not be available to support or uphold international peace if a crisis erupted.
- In July 1933, President Roosevelt rejected proposals at the London World Economic Conference to collaborate on stabilizing international currency values.
- Later, in 1935, the U.S. Senate approved a temporary Neutrality Act, which was expanded into a more comprehensive version in 1937.
- The growth of authoritarian regimes as a response to the Great Depression did not happen only in Europe, it was a global phenomenon.
- In Paper 2 - Topic 10: Authoritarian States, we will see the case study of Juan Perón in Argentina as one of these examples in the Americas region.
2. The League of Nations Failed as a Peace Keeping Body
- The League came into existence in January 1920, as part of the results of the Paris Peace Conference in Versailles.
- In 1920 there were 42 countries in the League, and in 1933 (before Japan and Germany leave in that year), membership peaked to 60 countries.
- As an aim, it strove for collective peace sustained by the goodwill and collaboration of member countries. Nevertheless, it had initial structural weaknesses:
- The Assembly of the League had one representative from each country.
- They could vote on general policies and budget, but for important decisions, such as the ones related to security, they needed a unanimous vote.
- This means that decisions were difficult to achieve, because if only one country refused a proposal, it would not pass.
- The Security Council was made up by permanent and non permanent members.
- The first permanent members were Britain, France, Italy, and Japan, and they all had veto power.
- That meant that decisions over borders, potential military intervention and sanctions had to be fully agreed upon. Again, a difficult task!
- Important countries were absent.
- Even when the League was the brainchild of Woodrow Wilson, the US president at the time, the US Congress did not approve of the US joining the League: they were adamant of focusing on isolationism.
- The Assembly of the League had one representative from each country.
- The lack of support of the US impacted on the League both economically and symbolically.
- Also, it was a flaw that two of the most powerful states in Europe, Germany and Russia, were not members from the beginning.
- The League did not have an army of its own.
- As a peacekeeping organization, the League relied on cooperation and common values and interests to foster diplomacy instead of military clash.
- Nevertheless, articles 10-16 of the covenant of the League did explicitly state the concept of “collective security”: if one country of the League got attacked by a third party, all the other members would join to protect the one being attacked.
- Also, article 16 stated that if a member resorted to war in violation of the Covenant, it would be considered an act of war against all members, and economic and military sanctions could be applied.
- During the 1920s the League was overall respected and its decisions abided by.
- For example, they were able to sort out conflict in Upper Silesia, in the Aaland Islands and prevented hostilities between Greece and Bulgaria, among other successes.
- But in the 1930s, it had major failures.
- The inaction in Manchuria, as we have seen, undermined its credibility and prompted Japan to leave the League.
- When Hitler got to power, he withdrew from the League and in 1935-6, the international organization faced a death blow in the conflict of Abyssinia (see the section on Italian expansion).
The League of Nations is an institution created during the Peace settlement in Paris, but it is not the same as the Treaty of Versailles, which dealt with Germany after they lost WW1.
- We have organized the reasons for the end of collective security in two main blocs:
- It failed because the Great Depression made expansionist authoritarianism rise.
- It failed because the international organizations meant to protect peace were not successful in deterring aggression.
- Which one do you think is the most relevant?
- Does the war start because it can’t be prevented?
- Or because there are aggressors that will wage war no matter what?
This question can be tackled with an intentionalist/structuralist historiographical outlook, as we have seen for Hitler in the section of Impact of Fascism and Nazism on the Foreign Policies of Italy and Germany.
