, the leader of the
Carlist cause and pretender to the
Spanish throne. After their fall from grace in 1823 at the hands of a French invasion, Spanish liberals had pinned their hopes on Ferdinand VII's spouse
Maria Cristina of Bourbon-Two Sicilies, who bore some marks as a liberal and a reformer. However, when she became regent for her daughter
Isabella in 1833, she made it clear to the court that she intended no such reforms. Even still, an alliance of convenience was formed with the
progresista faction at court against the conservatives, who backed the rebel
Infante Carlos of Spain. Carlos, who declared his support for the ancient, pre-
Bourbon privileges of the
fueros, received considerable support from the
Basque country, Aragon, and
Catalonia, which valued their ancient privileges from
Madrid. The insurrection seemed, at first, a catastrophic failure for the Carlists, who were quickly driven out of most of Aragon and Catalonia, and forced to cling to the uplands of Navarre by the end of 1833. At this crucial moment, however, Carlos named the
Basque Tomás de Zumalacárregui, a veteran
guerrilla of the
Peninsular War, to be his
commander-in-chief. Within a matter of months, Zumalacárregui reversed the fortunes of the Carlist cause and drove government forces out of most of Navarre, and launched a campaign into Aragon. By 1835, what was once a band of defeated guerrillas in Navarre had turned into an army of 30,000 in control of all of Spain north of the
Ebro River, with the exception of the fortified ports on the northern coast. General
Tomás de Zumalacárregui. Zumalacárregui, a
Basque, saved the Carlist cause from the brink of disaster in 1833. The position of the government was growing increasingly desperate. Rumors of a liberal coup to oust Maria Cristina abounded in Madrid, compounding the danger of the Carlist army which was now within striking distance of the capital. Appeals for aid did not fall on deaf ears; France, which had
replaced the
reactionary monarchy of
Charles X with the liberal monarchy of
Louis-Philippe in 1830, was sympathetic to the Cristino cause. The
Whig governments of
Viscount Melbourne were similarly friendly, and organized volunteers and material aid for Spain. Still confident of his successes, however, Don Carlos joined his troops on the battlefield. While Zumalacárregui agitated for a campaign to take Madrid, Carlos ordered his commander to take a port on the coast. In the subsequent campaign, Zumalacárregui died after being shot in the calf. There was suspicion that Carlos, jealous of his general's successes and politics, conspired to have him killed. Having failed to take Madrid, and having lost their popular general, the Carlist armies began to weaken. Reinforced with British equipment and manpower, Isabella found in the
progressista general
Baldomero Espartero a man capable of suppressing the rebellion; in 1836, he won a key victory at the
Battle of Luchana that turned the tide of the war. After years of vacillation on the issue of reform, events compelled Maria Cristina to accept a
new constitution in 1837 that substantively increased the powers of the Spanish parliament, the
cortes. The constitution also established state responsibility for the upkeep of the church, and a resurgence of
anti-clerical sentiment, led to the disbandment of some religious orders which considerably reduced the strength of the
Church in Spain. The
Jesuits – expelled during the
Trienio Liberal and readmitted by
Ferdinand VII – were again expelled by the wartime regency in 1835. . Mendizábal proposed the
sale of church property (desamortización) by the state as a solution to Spain's financial woes. The Spanish government was growing deeper in debt as the Carlist war dragged on, nearly to the point that it became insolvent. In 1836, the president of the government,
Juan Álvarez Mendizábal, offered a program of
desamortización, the
Ecclesiastical Confiscations of Mendizábal, that involved the confiscation and sale of church, mainly monastic, property. Many liberals, who bore anti-clerical sentiments, saw the clergy as having allied with the Carlists, and thus the
desamortización was only justice. Mendizábal recognized, also, that immense amounts of Spanish land (much of it given as far back as the reigns of
Philip II and
Philip IV) were in the hands of the church lying unused – the church was Spain's single largest landholder in Mendizábal's time. The Mendizábal government also passed a law guaranteeing
freedom of the press. After Luchana, Espartero's government forces successfully drove the Carlists back northward. Knowing that much of the support for the Carlist cause came from supporters of regional autonomy, Espartero convinced the Queen-Regent to compromise with the
fueros on the issue of regional autonomy and retain their loyalty. The subsequent
Convention of Vergara in 1839 was a success, protecting the privileges of the
fueros and recognizing the defeat of the Carlists. Don Carlos again went into exile. Freed from the Carlist threat, Maria Cristina immediately embarked on a campaign to undo the Constitution of 1837, provoking even greater ire from the liberal quarters of her government. Failing in the attempt to overthrow her own constitution, she attempted to undermine the rule of the municipalities in 1840; this proved to be her undoing. She was forced to name the
progressista hero of the
Carlist War, General Espartero, president of the government. Maria Cristina resigned the regency after Espartero attempted a program of reform. In the absence of a regent, the
cortes named Baldomero Espartero to that post in May 1841. Although a noted commander, Espartero was inexperienced with politics and his regency was markedly authoritarian; it was arguably Spain's first experience with military rule. The government wrangled with Espartero over the choice of
Agustín Argüelles, a radical liberal politician, as the young queen's tutor. From Paris, Maria Cristina railed against the decision and attracted the support of the
moderados in the
cortes. The war heroes
Manuel de la Concha and
Diego de León attempted a coup in September 1841, attempting to seize the queen, only months after Espartero was named regent. The severity with which Espartero crushed the rebellion led to considerable unpopularity; the
cortes, increasingly rebellious against him, selected an old rival,
José Ramón Rodil y Campillo, as their chief minister. Another uprising in
Barcelona in 1842 against his
free trade policies prompted him to bombard the city, serving only to loosen his tenuous grip on power. On 20 May 1843,
Salustiano Olózaga delivered his famous "Dios salve al país, Dios salve a la reina!" (God save the country, God save the queen!) speech that led to a strong moderate-liberal coalition that opposed Espartero. This coalition sponsored a third and final uprising led by generals
Ramón Narváez and
Francisco Serrano, who finally overthrew Espartero in 1843, after which the deposed regent fled to England. ==Moderado rule (1843–1849)==
