Pedro II inherited an empire on the verge of disintegration, but he turned Brazil into an emerging power in the international arena. The nation grew to be distinguished from its Hispanic neighbors on account of its political stability, zealously guarded freedom of speech, respect for civil rights, vibrant economic growth, and form of government—a functional representative parliamentary monarchy. Brazil was also victorious in the Platine War, the Uruguayan War, and the Paraguayan War, as well as prevailing in several other international disputes and domestic tensions. Pedro II steadfastly pushed through the abolition of slavery despite opposition from powerful political and economic interests. A savant in his own right, the Emperor established a reputation as a vigorous sponsor of learning, culture, and the sciences, and he won the respect and admiration of people such as Charles Darwin, Victor Hugo, and Friedrich Nietzsche, and was a friend to Richard Wagner, Louis Pasteur, and Henry Wadsworth Longfellow, among others.
