The first thing the new monarch did was to proclaim a general amnesty. He not only pardoned the rebel nobles, but raised some of them to posts of honor and confidence. This was not only politic but just, since their offences were mainly due to fear of the usurper. Under the circumstances he could safely treat them with magnanimity.
He next remodelled the government of the kingdom, and framed a code of laws which seemed so wise that it was adopted by his allies, the Aztecs and Tlacopans. Councils of war, of finance, and of justice were established, and also a council of state, whose members acted as the immediate advisers of the king, and aided him in the despatch of business. But the most remarkable of these new departments was the "council of music," which was devoted to the encouragement of science and art, and served as a general board of education for the country. Historical compositions and poems were recited before it, and altogether it indicated a degree of civilization which we would scarcely look for in any part of ancient America. Its historians, orators, and poets became celebrated throughout the country, the allied monarchs presided over its deliberations, and among its chief bards was the king himself, who entered into impartial competition with his subjects for the prizes given for the best poems. Many of his odes were long preserved, and may perhaps still rest in the dusty archives of Mexico or Spain.
The far-seeing monarch did not content himself with writing poetry, or encouraging historians,—who wrote subject to the penalty that any one who wilfully lied should be punished with death,—but he sought to develop all the arts. Agriculture was greatly encouraged, the population rapidly increased, new towns and cities sprang up, and the borders of the nation were extended by successful wars. He made his capital the most stately city of the land. Special edifices were built for his nobles, whom he wished to reside at the court. There were more than four hundred of these palatial mansions, but far exceeding them in magnificence was the grand palace he built for himself. This covered a space of three thousand seven hundred feet in length and nearly three thousand feet in width. A wall surrounded it, enclosing an outer court which formed the great market-place of the city, and an inner one surrounded by the council chambers and halls of justice. There were apartments for ambassadors from other states, and a spacious saloon in which the poets and men of science met to study and converse. Here also were kept the public archives.
