Revolutions, in opposing castes and uplifting the half-breed, prepared the way for a new period. But a democratic society cannot easily establish itself in the face of the established aristocracies, and slavery still survived, although softened by liberal institutions. The military class, accessible to all, replaced the old nobility. Confusion of races commenced as early as 1850, when generous laws enfranchised the negroes, and new economic interests arose to complicate these democratic societies. Revolutions, dictatorships, and anarchy were the necessary aspects of the dissolution of the old society. The age of generals gave way to an industrial period in which wealth increased, industries became more complex and numerous, and labour was subdivided, while association became more usual both in commerce and agriculture. Co-operation, organisation, and solidarity, unknown during the period of anarchy, were aspects of an intense economic development. The interests newly created sought for peace, and the internal order which favoured their expansion. Politics commenced to eschew and disdain the squabbles of ideology, and constitutional liberties acquired precision and efficacy. Plutocracies came into being, and aspired to government in place of internal revolution and external warfare; immigration, transforming the social classification, facilitated their advent. National progress was effected despite the governments; it was an anonymous and collective task. The energetic individualities of the military epoch were followed by the laborious crowd. The _caudillo_ receded to the background of politics; the captains of industry replaced him, the merchants and the bankers. Courage was once the supreme criterion of the man; now wealth is the touchstone by which individuals and peoples are judged. The table of human values changes; instruction, {95} foresight, and practical common sense determine success in an industrial democracy. In the social ascension of the generations which industry and commerce have thrown forward to the attack upon the old patrician society, the prejudices of class and religion grow feebler, and after a century of conflict the nations of the present day emerge. In the southern republics of America industrialism is supreme in the Argentine, Uruguay, and Chili; even in tropical Brazil. In Bolivia and Peru the last leaders are not yet dead, the parties are still personal, but their influence is not as decisive as it was thirty years ago. Among the northern peoples, from Mexico to Ecuador, anarchy and _caudillism_ still survive; there political unrest has not yet been dominated by the principle of authority. The long dictatorship of General Castro and certain Central American presidents proves that the dictatorial _régime_ is the only form of government that is able to maintain peace in these countries.
