The governor-intendente, Juan N. Batres, together with the ayuntamiento of Ciudad Real, proclaimed, on the 3d of September, 1821, the separation of Chiapas from Spain, and her acceptance of Iturbide's plan of Iguala. On the 8th all the authorities and officers, civil and military, took the oath to support that act, which was administered by the governor of the diocese; after which they had high mass and a sermon in the cathedral, where the secular clergy and the people took the same oath[II-45] before the aforesaid ecclesiastic authority. The obligations assumed were to support the Roman catholic apostolic religion; to secure the independence of the empire, preserving to that end peace and union between Europeans and Americans; and to obey Fernando VII., should he adopt and swear to support the constitution to be enacted by the córtes of the Mexican empire. Chiapas was, therefore, the first province of the captain-generalcy of Guatemala to throw off the Spanish yoke; she at the same time separated herself from Guatemala, and manifested her determination to link her future with Mexico. All this was made known September 21st by the comandante-general of Oajaca to Iturbide. The example of Ciudad Real was unhesitatingly followed by the other towns in the province. We have seen that Guatemala, at her declaration of independence, did not at once accept annexation to the Mexican empire. This course did not suit the rulers and notables of Ciudad Real, who hastened to manifest their displeasure at a meeting held September 20th, and attended by the intendente, ayuntamiento, and other official bodies, prelates, and a large number of citizens. [Sidenote: CHIAPAS A PART OF MEXICO.] As a matter of fact, the desire of Chiapas to be detached from Guatemala and annexed to Mexico existed with some strength even before the declaration of independence;[II-46] and Guatemala having failed to return an answer to the letter from the authorities of Chiapas, announcing her action of the 3d, this neglect had strengthened the notables of the latter in their resolution to recognize no other government than that of the Mexican empire under the treaties of Córdoba. It was also resolved at the meeting not to circulate the declaration of independence which the jefe político of Guatemala had sent. These sentiments were duly seconded by the other cities and towns. In order to guard against any action Guatemala might take because of the course of Chiapas, at a formal session of the diputacion, presided over by the jefe político, and held on the 22d of October, it was resolved to send to Mexico a commissioner to take the necessary steps, and procure his province's separation from Guatemala, even if the latter should come to be thereafter a part of the Mexican empire.[II-47] CHAPTER III.
