The occasion of the alleged journey was the recent discovery and conquest of Peru by Francisco Pizarro and Diego de Almagro. The fate of these millions of people, newly subjected to the Castilian crown could not have been a matter of indifference to Las Casas. They stood far higher in the scale of civilisation than the naked islanders, possessing as they did, as great an empire as the Mexicans, with religion, laws, and literature of a high order of development. While the entrance of Las Casas into a monastic order was, in one sense, a retirement from the world, he had chosen a community whose members were as devoted to the defence of the Indians as he himself was, and while he had, when still a secular priest, sustained a stout fight, unaided save by such friends as chance and his own efforts might here and there secure him, he could, after his profession, count upon the moral and active support of one of the most powerful religious organisations of the age. His retirement, therefore, proved to be a period of refreshment, during which he reinforced his powers for continuing his propaganda and, while losing nothing of his original enthusiasm and determination, he returned to the scene of his former activity with renewed courage and a great religious Order at his back. Determined as he was to forestall a repetition in Peru of the exterminating cruelties perpetrated in the islands, he returned to Court in his Dominican habit, where he preached several times with great success. The gift of eloquence he had always possessed, and his eight years of study and meditation had furnished him with new weapons, which he wielded with the same fiery zeal that had characterised the first years of his apostolic championship. During the six months he remained in Spain, he obtained a royal cedula to be delivered to Pizarro and Almagro, positively prohibiting the enslavement of any of the natives of Peru for any reason, or in any manner whatsoever, as they were declared to be the free vassals of the King, and as much entitled to the possession of their liberty and property as were the natives of Castile itself. The obnoxious Bishop of Burgos had long since fallen into disgrace and was dead, so that Las Casas was free to carry on his negotiations with the India Council without encountering at every step the obstacles and delays his old enemy had formerly opposed to his projects.
