The prosaic details of politics and diplomacy are rarely permitted to impinge on this history of the ""leaf-eating, tortoise-like House of Savoy"" with royal weddings, funerals, fox-bunts and soirees occupying the stage most of the time. Perhaps it's just as well since author Katz has little but contempt for Italy, that ""ridiculous imitation of a Great Power."" The Risorgimento, for example, ""was nothing but the advance of the New Oppression,"" an orgy of false idealism which saw ""not a moment of glory."" Wild-eyed Mazzini led straight to power-crazed Mussolini and his ""nationalist dialectics would one day be the cornerstone of Fascist philosophy""; in the interim, the regimes of Depretis, Crispi and Giolitti were the sorriest of excuses for parliamentarianism. Katz fills in the amours of Victor Emmanuel II, Humbert II and Margherita -- with particular attention to that lady's ""intolerance, bigotry, chauvinism, xenophobia and religious fanaticism."" On Victor Emmanuel III and Yolanda and the luckless Humbert III whose thirty-four-day reign brought the dynasty (""nine hundred years of earthbound cunning, parsimony, phlegmatism (sic), fragility, incredible selfishness"") to a close. Those seeking a more judicious appraisal of the role of the monarchy in the making of the modern Italian state should stick to the standard works of Dennis Mack Smith and Salvemini.
