With Iturbide's imperial regency came a new trouble to California, largely provoked by thoughts of the great wealth of the Missions. The imperial decree creating the regency was not announced until the end of 1821, and practically all California acquiesced in it. But in the meantime Agustin Fernandez de San Vicente had been sent as a special commissioner to "learn the feelings of the Californians, to foment a spirit of independence, to obtain an oath of allegiance, to raise the new national flag," and in general to superintend the change of government. He arrived in Monterey September 26, but found nothing to alarm him, as nobody seemed to care much which way things went. Then followed the "election" of a new governor, and the wire-pullers announced that Luis Argüello was the "choice of the convention."

In 1825 the Mexican republic may be said to have become fairly well established. Iturbide was out of the way, and the politicians were beginning to rule. A new "political chief" was now sent to California in the person of José Maria Echeandía, who arrived in San Diego late in October, 1825. While he and his superiors in Mexico were desirous of bringing about secularization, the difficulties in the way seemed insurmountable. The Missions were practically the backbone of the country; without them all would crumble to pieces, and the most fanatical opponent of the system could not fail to see that without the padres it would immediately fall. As Clinch well puts it: "The converts raised seven eighths of the farm produce;--the Missions had gathered two hundred thousand bushels in a single harvest. All manufacturing in the province--weaving, tanning, leather-work, flour-mills, soap-making--was carried on exclusively by the pupils of the Franciscans. It was more than doubtful whether they could be got to work under any other management, and a sudden cessation of labor might ruin the whole territory."

Something must be done, so, after consultation with some of the more advanced of the padres, the governor issued a proclamation July 25, 1826, announcing to the Indians that those who desired to leave the Missions might do so, provided they had been Christians from childhood, or for fifteen years, were married, or at least not minors, and had some means of gaining a livelihood. The Indians must apply to the commandant at the presidio, who, after obtaining from the padre a report, was to issue a written permit entitling the neophyte and his family to go where they chose, their names being erased from the Mission register. The result of this might readily be foreseen. Few could take advantage of it, and those that did soon came in contact with vultures of the "superior race," who proceeded to devour them and their substance.

Between July 29 and August 3, 1830, Echeandía had the California diputacion discuss his fuller plans, which they finally approved. These provided for the gradual transformation of the Missions into pueblos, beginning with those nearest the presidios and pueblos, of which one or two were to be secularized within a year, and the rest as rapidly as experience proved practicable. Each neophyte was to have a share in the Mission lands and other property. The padres might remain as curates, or establish a new line of Missions among the hitherto unreached Indians as they should choose. Though this plan was passed, it was not intended that it should be carried out until approved by the general government of Mexico.

All this seems singular to us now, reading three quarters of a century later, for, March 8, 1830, Manuel Victoria was appointed political chief in Echeandía's stead; but as he did not reach San Diego until November or December, and in the meantime a new element had been introduced into the secularization question in the person of José María Padrés, Echeandía resolved upon a bold stroke. He delayed meeting Victoria, lured him up to Santa Barbara, and kept him there under various pretexts until he had had time to prepare and issue a decree. This was dated January 6, 1831. It was a political trick, "wholly illegal, uncalled for, and unwise." He decreed immediate secularization of all the Missions, and the turning into towns of Carmel and San Gabriel. The ayuntamiento of Monterey, in accordance with the decree, chose a commissioner for each of the seven Missions of the district. These were Juan B. Alvarado for San Luis Obispo, José Castro for San Miguel, Antonio Castro for San Antonio, Tiburcio Castro for Soledad, Juan Higuera for San Juan Bautista, Sebastian Rodriguez for Santa Cruz, and Manuel Crespo for San Carlos. Castro and Alvarado were sent to San Miguel and San Luis Obispo respectively, where they read the decree and made speeches to the Indians; at San Miguel, Alvarado made a spread-eagle speech from a cart and used all his eloquence to persuade the Indians to adopt the plan of freemen. "Henceforth their trials were to be over. No tyrannical priest could compel them to work. They were to be citizens in a free and glorious republic, with none to molest or make them afraid." Then he called for those who wished to enjoy these blessings of freedom to come to the right, while those who were content to remain under the hideous bondage of the Missions could go to the left. Imagine his surprise and the chill his oratory received when all but a small handful quickly went to the left, and those who at first went to the right speedily joined the majority. At San Luis and San Antonio the Indians also preferred "slavery."

By this time Victoria began to see that he was being played with, so he hurried to Monterey and demanded the immediate surrender of the office to which he was entitled. One of his first acts was to nullify Echeandía's decree, and to write to Mexico and explain fully that it was undoubtedly owing to the influence of Padrés, whom he well knew. But before the end of the year Echeandía and his friends rose in rebellion, deposed, and exiled Victoria. Owing to the struggles then going on in Mexico, which culminated in Santa Anna's dictatorship, the revolt of Echeandía was overlooked and Figueroa appointed governor in his stead.

For a time Figueroa held back the tide of secularization, while Carlos Carrillo, the Californian delegate to the Mexican Congress, was doing all he could to keep the Missions and the Pious Fund intact. Figueroa then issued a series of provisional regulations on gradual emancipation, hoping to be relieved from further responsibility by the Mexican government.

This only came in the passage of an Act, August 17, 1833, decreeing full secularization. The Act also provided for the colonization of both the Californias, the expenses of this latter move to be borne by the proceeds gained from the distribution of the Mission property. A shrewd politician named Hijars was to be made governor of Upper California for the purpose of carrying this law into effect.

But now Figueroa seemed to regret his first action. Perhaps it was jealousy that Hijars should have been appointed to his stead. He bitterly opposed Hijars, refused to give up the governorship, and after considerable "pulling and hauling," issued secularization orders of his own, greatly at variance with those promulgated by the Mexican Cortes, and proceeded to set them in operation.

Ten Missions were fully secularized in 1834, and six others in the following year. And now came the general scramble for Mission property. Each succeeding governor, freed from too close supervision by the general government in Mexico, which was passing through trials and tribulations of its own, helped himself to as much as he could get. Alvarado, from 1836 to 1842, plundered on every hand, and Pio Pico was not much better. When he became governor, there were few funds with which to carry on the affairs of the country, and he prevailed upon the assembly to pass a decree authorizing the renting or the sale of the Mission property, reserving only the church, a curate's house, and a building for a court-house. From the proceeds the expenses of conducting the services of the church were to be provided, but there was no disposition made as to what should be done to secure the funds for that purpose. Under this decree the final acts of spoliation were consummated.
