The Age of Extremes: A History of the World, 1914-1991

Hobsbawm argues that the twentieth century was a 'short century' beginning with World War I in 1914 and ending with the Soviet collapse in 1991, rather than a calendar century. He divides it into the Age of Catastrophe (1914-1950), the Golden Age (1950-1973), and the Landslide (1973-1991). His central claim is that capitalism survived only because the socialist challenge forced it to reform, and that the century's end brought not liberal triumph but a dangerous erosion of public authority and social stability. He rejects the 'end of history' narrative as premature and complacent.

Hobsbawm argues the twentieth century as a meaningful historical period began in 1914 with the outbreak of World War I and ended in 1991 with the collapse of the Soviet Union. Before 1914, the world still belonged to the nineteenth-century order of liberal bourgeois progress; after 1991, a new and uncertain era began. This 'short century' was defined by the confrontation between capitalism and socialism, by total war, and by the unprecedented transformation of social life through technology and economic growth. The periodisation allows Hobsbawm to treat the era as a coherent unit with a distinct beginning and end.

Hobsbawm divides the period into three phases. The Age of Catastrophe (1914-1950) encompasses two world wars, the Russian Revolution, the Great Depression, the rise of fascism, and the Holocaust. The Golden Age (1950-1973) saw unprecedented economic growth, technological revolution, decolonisation, and social transformation, with the world economy expanding at rates never before seen. The Landslide (1973-1991) brought mass unemployment, economic crisis, the end of the postwar boom, and the eventual collapse of the Soviet bloc. Hobsbawm argues the Golden Age was the century's true anomaly, not its norm.

The Age of Extremes culminates Hobsbawm's evolving analysis of nationalism, moving from his earlier view of nationalism as a bourgeois distraction from class struggle to a late critique driven by the post-Soviet resurgence of ethnic nationalism. In Nations and Nationalism Since 1780 (1990), Hobsbawm had already predicted the decline of classical state-building nationalism. The collapse of communism and the eruption of ethnic conflicts in the former Yugoslavia and elsewhere confirmed his pessimism, and he came to view nationalism as one of the causes of communism's fall. The book's gloomy conclusion reflects his belief that the disappearance of socialist alternatives left nationalism and market forces unchecked.

Reception was sharply divided along ideological lines. Foreign Affairs called it a work of 'great insight coupled with extraordinary blindness,' praising its erudition while accusing Hobsbawm of failing to come to terms with capitalism's ability to raise living standards and foster democracy . Eugene Genovese, writing in The New Republic, praised Hobsbawm's realism and willingness to criticise the left, calling him 'the greatest of Marxist historians' . A 2024 re-review concluded the book 'deserves' classic status, noting it rewards readers 'not because a historian would write the same book today but precisely because they would not' .

Hobsbawm's 1994 conclusion that capitalist democracy faced serious crisis and could not resolve problems of overpopulation and environment has been partially vindicated and partially challenged. The decades since have seen rising inequality, financial crises, and ecological deterioration, but also sustained economic growth in parts of Asia that Hobsbawm underweighted. The book's greatest strength remains its synthesis and its refusal to accept the 'end of history' triumphalism of the 1990s. Its greatest weakness is its Marxist framework, which led Hobsbawm to underestimate capitalism's adaptive capacity and to dismiss phenomena that did not fit his model.
