The Secretaries-General
How the UN's top diplomats shaped the organization through personal leadership, from Dag Hammarskjold's activist vision to the modern era.
The World's Most Impossible Job
The UN Secretary-General is often called the world's most impossible job. The Charter describes the role as the organization's 'chief administrative officer,' but in practice, Secretaries-General have served as global diplomats, crisis managers, moral authorities, and bureaucratic leaders. The position's power depends almost entirely on the individual's personality, political skill, and the willingness of major powers to let them act. The first Secretary-General, Trygve Lie of Norway (1946-1952), set the precedent for political engagement by supporting the UN's response to the Korean War, which earned him Moscow's lasting hostility.
Dag Hammarskjold of Sweden (1953-1961) transformed the office. He developed the concept of 'preventive diplomacy,' using the Secretary-General's good offices to defuse crises before they escalated. He personally negotiated the release of American prisoners from China and created the first UN peacekeeping force during the Suez Crisis of 1956. Hammarskjold's activism put him at odds with the Soviet Union, whose leader Nikita Khrushchev demanded the position be replaced by a three-person 'troika.' Hammarskjold died in a suspicious plane crash in the Congo in 1961, becoming the only Secretary-General to die in office.
