Criollo rebellion From 1810 to 1820, Iturbide had fought against those who sought to overturn the Spanish monarchy and
Bourbon dynasty's right to rule New Spain and replace that regime with an independent government. He was solidly aligned with the Criollos. That led to the disintegration of viceregal authority in Mexico City, and a political vacuum developed that the Mexican nobility sought to fill, seeking limited representation and autonomy for themselves within the empire. An idea arose in the class that if Mexico became independent or autonomous, and Ferdinand were deposed, he could become king of Mexico.
Alliance with Guerrero , between Iturbide (left) and
Guerrero (right), by
Ramón Sagredo Iturbide was convinced that independence for Mexico was the only way to protect the country from a republican tide. He decided to become the leader of the Criollo independence movement. However, to succeed, he would need to put together a very-unlikely coalition of Mexican liberal insurgents, landed nobility, and the
Church. Therefore, he penned The Plan of Iguala, which held itself up on Three Guarantees: Freedom (from Spain), Religion (with Catholicism being the only accepted religion in the new country) and Union (with all inhabitants of México to be regarded as equals). In that manner, he was paving the road to gaining the support of the most powerful factions: the insurgents, the clergy and the Spaniards. The plan envisioned a monarchy, thus assuring the support of the royalists as well. Iturbide held a series of negotiations with Guerrero and made a number of demonstrations of his intentions to form an independent Mexico. Iturbide offered Guerrero a full pardon if he surrendered. Guerrero rejected the pardon but agreed to meet with Iturbide to discuss the independence of Mexico. In the "
Embrace of Acatempán", named after the locale, they agreed to implement the plan, which was made public on 24 February 1821 by Iturbide, Guerrero, and another insurgent leader,
Guadalupe Victoria. On 1 March 1821, Iturbide was proclaimed head of the
Army of the Three Guarantees, with Guerrero fully supporting him and recognizing him as his leader.
Plan of Iguala The plan was a rather vague document that sought the transition of the center of power in New Spain from
Madrid to Mexico City. Essentially, the idea was to bring Ferdinand VII to Mexico City to rule. If he did not come to Mexico, another member of the Bourbon royal family would be chosen to rule there. If no European ruler would come to rule México, the nation would have the right to elect a ruler by its own people. To attract the disparate parties involved in the scheme, the plan offered three guarantees: Mexico would be independent from Madrid, Roman Catholicism would be the official religion, and all inhabitants of the new nation, later México, would be considered equals, with no distinction being made between Spaniards, Creoles, Mestizos, etc., thus eliminating the complicated caste system that had been used until then and abolishing the use of slaves in the territory of the new nation as well. The promise of independence convinced the insurgents to accept the proposal. The promise of the supremacy of the Roman Catholic Church was offered to the clergy, who were frightened by anticlerical policies of Spanish Liberalism. The offer of equality between Criollos and the Spanish-born
Peninsulares assured the latter that they and their property would be safe in the new state. That was important because the Peninsulares owned a significant part of the valuable real estate and many of the businesses in Mexico. If the Spaniards had left, that would have been disastrous for the Mexican economy. The plan gained wide support because it demanded independence without attacking the landed classes and did not threaten social dissolution. Therefore, Iturbide succeeded in bringing together old insurgents and royalist forces to fight against the new Spanish government and what was left of the viceregal government. Military leaders, soldiers, families, villages, and towns that had been fighting against one another for almost ten years found themselves joining forces to gain Mexican independence. However, their reasons for joining together were very different, and those differences would later foment the turmoil that occurred after independence. Both the sitting viceroy and Fernando VII rejected the Plan of Iguala. The
Spanish parliament sent a new "viceroy,"
Juan O'Donojú, to Mexico. (Technically, the office of viceroy had been replaced by a "superior political chief" under the 1812 Spanish Constitution.) O'Donojú, however, arrived to witness a nation on the brink of achieving independence and knew that its consummation could not be stopped. ==Independence and early transition==
