In the absence of a regent, the "cortes" named 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.
