O'DONOJU, LXII. VICEROY OF NEW SPAIN, ITURBIDE, EMPEROR OF MEXICO.--1821-1824. It will be seen by the Plan of Iguala, that Mexico was designed to become an independent sovereignty under Ferdinand VII. or, in the event of his refusal, under the Infantes Don Carlos and Don Francisco de Paula. Iturbide was still a royalist--not a republican; and it is very doubtful whether he would ever have assented to popular authority, even had his life been spared to witness the final development of the revolution. It is probable that his penetrating mind distinguished between popular hatred of unjust restraint, and the genuine capacity of a nation for liberty, nor is it unlikely that he found among his countrymen but few of those self-controlling, self-sacrificing and progressive elements, which constitute the only foundation upon which a republic can be securely founded. His ambition had not yet been fully developed by success, and it cannot be imagined that he had already fixed his heart upon the imperial throne. When the Plan of Iguala was proclaimed, the entire army of the future emperor, consisted of only eight hundred men, all of whom took the oath of fidelity to the project, though many deserted when they found the country was not immediately unanimous in its approval. In the capital, the viceroy appears to have been paralyzed by the sudden and unexpected movement of his officer. He paused, hesitated, failed to act, and was deposed by the Europeans, who treated him as they had Iturrigaray in 1808. Don Francisco de Novella, an artillery officer, was installed temporarily in his stead, but the appointment created a dissension among the people in the capital and the country, and this so completely prostrated the action of the central authorities, who might have crushed the revolution by a blow, that Iturbide was enabled to prosecute his designs throughout the most important parts of the interior of the country, without the slightest resistance.
