About the author
British historian and international-relations theorist (1892–1982). Written on the eve of the Second World War, The Twenty Years' Crisis (1939) is a founding text of IR realism, attacking the 'utopian' liberal faith in a natural harmony of interests and insisting that power and interest, not moral aspiration alone, govern relations between states. Carr's challenge to idealism set the terms for the realist–idealist debate in the discipline.
