These new commotions, and others of more importance which shall be noticed in the sequel, proceeded in a great measure from the imprudent conduct of the judges themselves, by enforcing the observance of the obnoxious regulations which had formerly done so much evil during the government of the viceroy Blasco Nunnez Vela. Just before his departure from Peru, the president Gasca had received fresh orders from his majesty to free the Indians from services to their lords: But having experienced that this had occasioned the most dangerous commotions in the country, he very wisely commanded before his departure that the execution of this new order should be suspended. The judges however, saw this matter in a different light, and circulated their commands over the whole kingdom to enforce this new royal order; which gave occasion to the mutinous and disorderly behaviour of the soldiery, who were encouraged in their rebellious disposition by many persons of consideration, the possessors of allotments of lands and Indians, who considered themselves aggrieved.
History of Peru during the Viceroyalty of Don Antonio de Mendoza.
About this time Don Antonio de Mendoza, the viceroy of Mexico, was appointed viceroy of Peru, and landed at Lima, where he was received with great demonstration of joy and respect. He was accompanied on this occasion by his son, Don Francisco de Mendoza, afterwards general of the galleys in Spain. Don Antonio was a nobleman of much sanctity, and had greatly impaired his health by long abstinence and frequent acts of penance; insomuch that his natural heat began to fail, and he was obliged to use violent exercise to keep him warm, even in the hot climate of Lima. In consequence of his want of health, he deputed his son Don Francisco to make a progress through all the cities of the kingdom, from Lima to Las Charcas and Potosi, to bring him back a faithful representation of the state and condition of the kingdom and its mines, to be laid before his majesty; and, after his return to Lima, Don Francisco was sent into Spain in 1552, to communicate an account of the whole kingdom to the emperor.
