The historical context of the Washington Conference
The Washington Conference was held in the post -war context of World War I. The “Great War” (as it was known at that time) had been the most destructive military conflict in the history of humanity and the amount of lives it took was an unprecedented fact.
At the end of the war in 1918, The victorious powers (France, the United Kingdom, Russia and the United States) established the bases of the future of Europe During the peace conferences of Paris (1919) and then signed a series of agreements with the different countries involved in the conflict (such as the Treaty of Versailles with Germany).
In those years the idea that If all countries limit the amount of weapons available, a safer international situation would be reached For everyone. This idea was known as “disarmament policy” and is the principle that guided some of the decisions of the Versailles treaty, such as the creation of the Nations Society, an international organization that aimed to improve relations between different countries.
In addition, through specific agreements we sought to resolve the territorial conflicts that involved the different powers. In this context, Nine countries decided to meet in Washington with the objective of agreeing a series of fundamental issues for the maintenance of international peace.
