In the early years of the twentieth century, Imperial Russia was an ethnically diverse empire, stretching from Ukraine and Belarus in the west to the Bering Sea and the Sea of Okhotsk in the Far East. At the head of this profoundly dysfunctional polity was Tsar Nicholas II, whose Romanov successors had ruled Russia since the start of the seventeenth century with a lethal mixture of domestic cruelty, expansionist energy and reactionary incompetence – interspersed with occasional reformist spasms.

By early 1917, Russia was unreformable, and the tsar's authority irreparably damaged. In March of that year, Nicholas II abdicated and the tsarist system was overthrown. The provisional government installed in its stead to organise democratic elections lasted just eight chaotic months before being ousted by Lenin's Bolsheviks in the October Revolution.

Writing with crisp immediacy, Sebestyen narrates an unprecedented era of political and social convulsion. The Russian Revolution changed the course of history, and, more than a century later, their backwash continues to be deeply felt across the world.
