Fred Anderson has demonstrated how a futuristic novel written in 1763 can help to shed light on British thinking about the long-term consequences of the peace [from the Seven Years’ War].  The anonymously published The Reign of George VI, 1900-1925 presents a scenario far in the future, in the early twentieth century.  The book’s counterhistorical narrative suggests that Britain, by granting far too generous a peace in 1763, unintentionally helped France and Russia become leading nineteenth-century world powers.  In the early twentieth century, the reign of George VI is thus dominated by Britain’s worldwide struggle to reestablish its position as a global power.  The conflict ends with Britain imposing peace in Paris in 1920, after British troops have “liberated” France, with George, the “philosopher king,” hailed as the bringer of freedom.  At the time the book was written in 1763, its primary target was clearly the British negotiators in Paris…
