First Mexican Empire

Coat of arms of the First Mexican Empire.

The Spanish Empire disintegrated in the wake of Napoleon's invasion of Spain and the overthrow of the Spanish Bourbons in 1808. Throughout Spain and her colonies there was a widespread refusal to recognize Napoleon's brother Joseph II as the new French-backed king of Spain. The cleric Miguel Hidalgo y Costilla, who had long been part of a circle of intellectuals who sought to reform the colonial system triggered the Mexican War of Independence in 1810 by accusing the Spanish ruling classes of seeking to recognize Joseph Bonaparte, while proclaiming loyalty to the imprisoned Ferdinand VII. The subsequent uprising would go on to seriously threaten the capital yet it was ultimately defeated within a year and Hidalgo was captured and executed. The insurgency survived however, and the cause of absolute independence from Spain was adopted by insurgent leaders such as José María Morelos. He was also defeated and after Morelos' execution in 1815, the remaining rebels were reduced to waging guerilla warfare in the countryside. Agustín de Iturbide was a Mexican officer in the Spanish army, representative of the Mexican elite who were initially loyal to Spain, but later saw their interests threatened by the liberal 1820 Revolution in Spain. In view of this, Iturbide began to lead a movement to pact with the remaining insurgents and support the separation of Mexico from the Spanish metropole.

The movement involved three principles, or "guarantees": that Mexico would be an independent constitutional monarchy governed by a Spanish prince; that Americanos, that is all those Mexican-born and those Spanish-born would henceforth enjoy equal rights and privileges; and that the Roman Catholic Church would retain its privileges and position as the official and exclusive religion of the land. These Three Guarantees formed the core of the Plan of Iguala, the revolutionary blueprint which, by combining the goal of independence and a constitution with the preservation of Catholic monarchy, brought together all Mexican factions.[4] Under the 24 February 1821 Plan of Iguala, to which most of the provinces subscribed, the Mexican Congress established a regency council which was headed by Iturbide.

Viceroy Juan O'Donojú acceded to the Mexican demands, and signed the Treaty of Córdoba on 24 August 1821. The Mexican Congress intended to establish a personal union, whereby King Fernando VII of Spain would also be king of Mexico, but both countries would be governed by separate laws and through separate legislative bodies. If the king refused the position, the law provided for another member of the House of Bourbon to accede to the Mexican throne.[5] Commissioners from Mexico were sent to Spain to offer the Mexican throne, but the Spanish government refused to recognise Mexico's independence and would not allow any other Spanish prince to accept the throne.

With Ferdinand VII having rejected the Treaty of Cordoba, Iturbide's supporters saw an opportunity to place their candidate on the throne. On the night of 18 May, the 1st infantry regiment, stationed at the ex Convent of San Hipólito, and led by sergeant Pio Marcha began a public demonstration in favor of Iturbide being made emperor. The demonstration was joined by other barracks and many civilians as well. When the public demonstration reached his home, Iturbide himself was able to address the demonstrators from his balcony. He consulted with members of the regency on what course to follow, and eventually acquiesced to the demonstrator's demands, agreeing that he should be made emperor. The crowd celebrated the rest of the night with fireworks and celebratory gunfire.[6]

An extraordinary session of congress was held the following morning to deal with the subject of Iturbide's coronation. At the opening of the session, the military addressed a manifesto to congress, endorsing Iturbide to be emperor. The deliberations then started with a few deputies expressing concern that congress was not entirely free in the present circumstances to proceed on the matter. A pro-Iturbide crowd outside of the hall was making so much noise that it was interfering with the deliberations, and congress asked Iturbide to show up in an unsuccessful attempt to calm the crowds. The opposition brought up concerns that a popular demonstration in the capital was not enough of a basis upon which to elect Iturbide and that the provinces ought to be consulted first. A proposal was made to gain the consent of two thirds of the provinces, and this succeeding then to appoint a commission to write a provisional constitution in order to avoid constitutional crises.[7]

Deputy Valentín Gómez Farías, future president of Mexico, stood up for the legality of congress to elect an emperor. He praised Iturbide's services to the nation, and argued that as Spain had rejected the Treaty of Córdoba, Congress was now authorized by that very treaty to hold an election to decide who the emperor was to be.[8] The vote then proceeded. In the final results, sixty-seven deputies voted in favor of making Iturbide Emperor, while fifteen voted against. The vote however was short of a legal quorum of one hundred and two deputies.[9] Congress, nonetheless resigned itself to the situation, and a plan to establish a constitutional monarchy united both conservatives and liberals at a time when it was uncertain which form of government would be best for independent Mexico.[10]

Congress published an oath binding the emperor to obey the constitution, which Iturbide subsequently took, and Congress also declared the Mexican monarchy to be hereditary, granting titles of nobility to Iturbide's family. His son and heir became Prince Imperial of Mexico. The 19th of May was made a national holiday, and a royal household was organized. 21 July 1822 was set as the date of the official coronation.[11]

Iturbide's court was being set up to be more luxurious than that of the former Spanish Viceroy, a situation which provoked opposition in a new nation that was essentially bankrupt. To remedy the financial difficulties, the Mexican government prohibited the exportation of money, and exacted a forced loan of 600,000 pesos in Mexico City, Puebla, Guadalajara, and Veracruz. During this time, a council of state was also formed, being made up of thirteen members selected by the Emperor from a list of thirty one nominees submitted by congress.[12]

The coronation took place on 21 July. The capital was decked out in floral arrangements, banners, streamers, and flags. The government could not afford to forge a crown, and therefore jewels and gems had to be borrowed, but ultimately a signet ring, a scepter and crowns were produced. Costumes were made based on drawings of Napoleon's coronation. Congress met on the morning of the coronation, and then divided itself into two deputations to escort the emperor and the empress to the National Cathedral. In the cathedral, the emperor and the empress were to be seated on thrones next to the newly ennobled Mexican princes and princesses. Upon reaching the cathedral, the emperor and empress were escorted to their thrones, and the imperial regalia was placed on the altar. The regalia was blessed and Iturbide was crowned by the president of the congress.[13]

Congress and the Emperor immediately began to clash, in large part because their respective legal powers had not at this point been clearly delineated. By mid 1822 the three major issues were whether Iturbide had a right to appoint members to a Supreme Court, whether he had the right to veto legislation as the Spanish King had under the Spanish Constitution of 1812, and his wish to establish rural military tribunals.[15] The latter measure was in response to the lapse in law and order that was spreading throughout the country. Iturbide wished to establish in provincial capitals special courts made up of two military officers assisted by a lawyer. They were to keep track of seditious plots, but also in cases of murder, robbery or injury, and with the permission of the district captain general, the courts would be allowed to disregard statutes that would interfere with quickly carrying out judicial processes. Congress however, was opposed to the project.[16] All the while, work on a constitution for the Empire was being neglected.[17] Iturbide's greatest enemy in congress was deputy Servando Teresa de Mier, a staunch republican, who would often ridicule the Emperor and his pageantry.[18]

The last Spanish stronghold in Mexico, was Fort of San Juan de Ullua on a small island off the coast of Veracruz. There had been a change in command at the fort during this time, and general Antonio López de Santa Anna, stationed in Veracruz planned a scheme of taking possession of it by feigning the surrender of Veracruz to its new commander. When Echevarri, the captain-general of the local provinces, arrived in Veracruz, he approved of the plan, and agreed to join in on it, positioning his troops in Veracruz to ambush the landing Spaniards, having been promised support by Santa Anna. On 26 October 1822, as the Spaniards landed however, Santa Anna's troops failed to arrive, and Echevarri barely defeated the landing party, and the Spanish ultimately kept control of the fort. Echevarri expressed his suspicion to Iturbide that it had all been a scheme by Santa Anna to get Echeverri killed as revenge for Santa Anna not having been appointed Captain-General himself. Iturbide himself went to Veracruz to dismiss Santa Anna from his command, not overtly however but rather under the pretext of simply moving him to a different post in Mexico City. However, Santa Anna suspecting his ruin, instead took command of his troops and in December, 1822 started a rebellion in favour of a republican form of government.[30]

Vicente Guerrero and Nicolas Bravo, defected from the ranks of the imperialists, and proceeded to Chilapa on 5 January 1823 to join the revolution, but experienced a disastrous defeat at Almolonga. The insurrection was mostly being suppressed at this time, Victoria being held in check at Puente del Rey, and Santa Anna still confined at Veracruz.[31]

Echevarri was sent to take care of the rebellion in Veracruz, with more than three thousand well supplied troops, but ended up defecting. At this point, the opposition to the government began to negotiate with the military. On 1 February 1823 a junta including many military chiefs, and the liberal diplomat Miguel Santa María met in Veracruz to proclaim the Plan of Casa Mata.[32] The army pledged itself to restore Congress while disavowing any intention of harming the person of the Emperor, or of overthrowing the Mexican monarchy. On 14 February, Puebla proclaimed for the plan, followed by San Luis Potosí, and Guadalajara. By March, most of Mexico had proclaimed in favour of the plan.[33] A military junta was formed in Jalapa, to represent the Plan of Casa Mata.

On 4 March 1823, Iturbide issued a decree reconvening Congress, and the deputies met on 7 March. Iturbide addressed the session, hoping to reach a negotiation and avoid conflict, but the deputies listened coldly. The military junta refused to recognize the Congress until its liberty was guaranteed. On 19 March, Iturbide fearing his imminent overthrowal, summoned congress to an extraordinary session and presented his abdication. Congress proposed that the military junta meet with Iturbide about the matter, but the junta refused, instead proposing that Iturbide remove himself from the capital, and await the decision of Congress. On 26 March, an agreement was reached by which the junta would recognize Iturbide on whatever terms Congress would grant him. Iturbide also agreed to remove himself from the capital, and the command of the capital was handed over to the revolutionary troops and power passed over to the Provisional Government of Mexico.[34]

Provinces of the Empire.

  Treaty of Córdoba

  Acquisitions (1821–1822)

The territory of the Mexican Empire corresponded to the borders of Viceroyalty of New Spain, excluding the Captaincies General of Cuba, Santo Domingo and the Philippines. The Central American lands of the former Captaincy General of Guatemala were annexed to the Empire shortly after its establishment.[35]

Under the First Empire, Mexico reached its greatest territorial extent, stretching from northern California to the provinces of Central America (excluding Panama, which was then part of Colombia), which had not initially approved becoming part of the Mexican Empire but joined the Empire shortly after their independence.[36]

After the emperor abdicated, on March 29 the departing Mexican general Vicente Filísola called for a new Central American Congress to convene and on July 1, 1823 the Central American provinces formed the Federal Republic of Central America, with only the province of Chiapas choosing to remain a part of Mexico as a state. Subsequent territorial evolution of Mexico over the next several decades (principally cessions to the United States) would eventually reduce Mexico to less than half its maximum extent.
