Manuel Gutiérrez de la Concha e Irigoyen, Marquis of the Duero, was a 19th-century Spanish military man and Liberal-Moderate politician, noted for opposing the Carlist rebellions. He was born in Córdoba del Tucumán, Viceroyalty of the Río de la Plata (now Córdoba, Argentina), on 3 April 1808, and died at Monte Muro, Navarre, on 27 June 1874. Biography Manuel de la Concha was born in Córdoba in present-day Argentina. His mother was Petra Irigoyen and his father was Juan Gutiérrez de la Concha y Mazón, brigadier de marina (naval officer), and later gobernador intendente (governor) of the province of Tucumán. His father was killed during the fighting that followed the May Revolution in 1810. In 1814 the family moved to Spain, where Manuel de la Concha began his schooling. He entered the Royal Guard as a cadet in 1820, was promoted to alférez (second lieutenant) in 1825 and to lieutenant in 1832. He became a supporter of the Liberals, for which he spent some months in prison before the death of Fernando VII. He was released during the First Carlist War, and joined the supporters of Isabella II. He was posted to the Army of the North and distinguished himself in the actions at Durango, Alsasua and Zúñiga, being awarded the Cross of San Fernando. In April 1836 he was given his first military command in recognition of his bravery in battle. He received further promotions and reached the rank of lieutenant-colonel after the conquest of Urrieta. The battle of Belascoáin earned him a second Cross of San Fernando and promotion to colonel. He became mariscal de campo (a rank between brigadier and lieutenant-general) in 1840. He then took part in the campaign of Arróniz, and won a third Cross of San Fernando. He supported the Moderate (moderado) party. In 1841 he was appointed comandante general (commanding general) of the provinces of Guadalajara and Cuenca. In October 1841, along with Diego de León and other military men and moderado politicians, he took part in the failed attempt to end the regency of Espartero, and due to this he was compelled to go into exile in Florence. In the summer of 1843 he took an active part in the fall of Espartero, brought about by Narváez, and this earned him promotion to lieutenant-general. The moderados who gained power appointed him inspector-general of the infantry, and later captain-general of Old Castile. In
