To most non-Italians Turin spells Fabbrica Italiana Automobili Torino (Fiat). But this subalpine city has a longer history than the internal combustion engine. It may be twinned with Detroit, but its cavalcade of equestrian monuments testifies to an older sort of horsepower — the sort harnessed by the condottieri of the House of Savoy to turn their little Duchy into a major player on the European stage and, for four brief years from 1861 to 1865, into the capital of the Kingdom of Italy.
