1. The Short Century as a Historical Argument
Hobsbawm's decision to frame the twentieth century as running from 1914 to 1991 is itself an analytical claim, not merely a convenience. He argues that the world shaped by the long nineteenth century, with its relative stability, its liberal assumptions, and its European dominance, ended definitively when the war began in 1914. The Soviet collapse in 1991 then closes the bracket, because it marks the end of the ideological system that 1914 and 1917 together made possible. Treating any other dates as the century's real boundaries would, in his view, obscure the inner coherence of the period.
Why it matters: This framing challenges readers to think about historical periodisation as interpretation rather than fact, and it invites comparisons with scholars who see the century differently, for instance those who regard 1945 or 1989 as the more fundamental dividing lines.
