Timeline of the Cold War

At its simplest, the Cold War is said to have begun in 1947. However, roots of distrust and tension which are the underlying factors in causing the Cold War can be directly traced back to the outbreak of the First World War in 1914. The timeline also lists important dates in the origins of the Cold War, although this page attempts to give a brief explanation on how the events impacted the Cold War.
