In international relations, the term middle power refers to a state that wields less influence on the world stage than a superpower. As the term suggests, middle powers fall in the middle of the scale measuring a country’s international influence. Where superpowers have great influence over other countries, middle powers have moderate influence over international events. Canada was considered to be a middle power during the postwar period — from 1945 until about 1960. Though Canada was not as powerful or prominent as the United Kingdom or the United States during this time, it was an international player that influenced events through moral leadership, peacekeeping and conflict mediation.
