A summit meeting (or just summit) is an international meeting of heads of state or government, usually with considerable media exposure, tight security, and a prearranged agenda. Notable summit meetings include those of Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin during World War II. However, the term summit was not commonly used for such meetings until the Geneva Summit (1955).[1] During the Cold War, when American presidents joined with Soviet or Chinese counterparts for one-on-one meetings, the media labelled the event as a "summit". The post–Cold War era has produced an increase in the number of "summit" events. Nowadays, international summits are the most common expression for global governance.[2]
