When Napoleon Bonaparte captured Venice in 1797, he extinguished what had been the most successful regime in the history of the western world. The Venetian Republic had lasted over 1,000 years — longer than ancient Rome — without a revolution, a coup d’état or a successful foreign invasion.  Yet after 1797 it was never to be independent again: it was given to Austria, taken back by France, allotted once more to Austria and finally, in 1866, handed over to the young Kingdom of Italy.
