What if the First World War had gone differently?

Four years of industrial war break four empires and redraw the map from Berlin to Baghdad.

1. 1917The Russian Revolution, The Russian monarchy reforms or muddles through; the century-long contest between communism and capitalism never begins.
2. 1918Women win the vote, Half the population stays voteless into mid-century; mass democracy is only ever half a democracy.
3. 1936Keynesian economics, Governments keep treating slumps as bad weather; the idea that the state can manage demand never becomes orthodoxy.
