The ministry of Viscount Rio Branco, from 1871 to 1876, maintained the _status quo_. A great administrator, {189} like the Marquis de Parana, he effected a reform in public education by founding special schools; he took a census of the country, and extended the network of railways. Immigration increased under his government and exchange was bettered. A great social reform changed the face of the Empire; in 1871 slavery was abolished. The separated classes were about to mingle with the nation; the result was the rise of a mestizo democracy. Slavery abolished, castes confounded, liberals discontented, the reactionaries growing old--on the doubtful horizon one supreme hope was visible: the republic. It was now the collective ideal, as the Empire had been in the last days of the colonial period. It was proclaimed, without violence, in 1889. The Emperor, who abdicated, a symbol of the majestic past, had prepared the advent of the Republic that ostracised him. His ideas were liberal; he was the protector of the sciences; a smiling philosopher; and in fostering the intellectual transformation of Brazil he exposed his own autocracy to the criticism of the liberals. By abolishing slavery he weakened the power of the reigning oligarchy; by destroying privileges and uniting hostile classes he created a democracy. The Empire, in America, represents tutelary authority. Between the feudal colony and the Republic--two extreme points of political development--arose the Brazilian monarchy, as a moderative power. It brought a necessary equilibrium, and, with that, progress. First of all it established autonomy; then a national order, a national dynasty; it preserved traditions, and organised the forces of society. Beside it arose a conservative oligarchy, bound to the soil; castes and permanent interests were created. The territorial overlords upheld the stability of the Empire, and an admirable political system imposed peace upon a heterogeneous people, {190} shaken by the clash of races and the opposition of seaboard and province. Between 1848 and 1862 the monarchy created the Brazilian nation.
