Revolutions do not occur directly from abuses of power, for in that case there would be nothing but revolution all the time, since every dominant crowd has abused its power. It is an interesting fact that revolution generally occurs after the abuses of which the revolutionists complain have been in great measure stopped--that is, after the ruling crowd has begun to make efforts at reform. The Reformation occurred in the pontificate of Leo X. If it had been the result of intolerable abuse alone, it would have happened in the time of Alexander VI, Borgia. The French Revolution fell upon the mild head of Louis XVI, though the wrongs which it tried to right mostly happened in the reign of his predecessor. In most cases the abuses, the existence of which a revolutionary crowd uses for propaganda purposes, are in turn repeated in new form by itself after it becomes dominant. The Reformers in the sixteenth and seventeenth centuries resorted to much the same kind of persecution from which they had themselves earlier suffered. The Constituent Assembly, though it had demanded liberty, soon set up a more outrageous tyranny through its own committees than any that the Louies had dreamed of. Bolshevists in capitalist countries are the greatest advocates of free speech; in Russia they are the authors of a very effective press-censorship. No, it is hardly the abuses which men suffer from their ruling crowds which cause insurrection. People have borne the most terrible outrages and suffered in silence for centuries. Russia itself is a good example of this. _A revolution occurs when the dominant crowd begins to weaken._ I think we find proof of this in the psychology of revolutionary propaganda. A general revolution is not made in a day, each such cataclysm is preceded by a long period of unrest and propaganda of opposition to the existing order and its beneficiaries. The Roman Republic began going to pieces about a hundred years before the battle of Actium. The social unrest which followed the Punic Wars and led to the revolt of the brothers Gracchi was never wholly checked during the century which followed. The dominant party had scarcely rid itself of these troublesome "demagogues" than revolt broke out among the slave population of Sicily. This was followed by the revolt of the Italian peasants, then again by the insurrection of Spartacus, and this in turn by the civil war between Marius and Sulla, the conspiracy of Catiline, the brief triumph of Julius Cæsar over the Senate, the revenge of the latter in the assassination of Cæsar, and the years of turmoil during the Second Triumvirate.
