JAUREGUI y ALDECOA, Agustin de, viceroy of Peru, born in Bazan, Navarre, in 1708; died in Lima, Peru, 27 April, 1784. In his youth he was equerry to Philip V., who afterward appointed him captain of dragoons. In 1740, having been promoted lieutenant-colonel of his regiment, he joined the expeditionary force that was sent to the West Indies to protect them against the British. With a division of 3,000 men he was in the expedition to Honduras, and his regiment took part in the capture of the island of Ruatan. On his return to Spain he was promoted brigadier by Charles III. in 1753, and in 1762 participated in the campaign of Portugal, and was promoted major-general. In 1772 he was appointed president and governor of Chili, and took possession of his office in 1773. During his administration the audiencia of Chili was established in 1776, and in 1779 he was active in preparing to defend the country against a threatened invasion by the British. He was then promoted to lieutenant-general, appointed viceroy of Peru, and received the government from his predecessor on 21 July, 1780. He found the country in a difficult situation on account of the threatened rising of the natives in the interior, and, while he was preparing to resist the British fleet under Admiral Hugues, which had forced an entry to the Pacific, he received the news of the revolution under Tupac-Amard. (See CONDORCANQUI.) By the active measures that were taken by Jauregui, the insurgents were decisively defeated, 6 April, 1781, and the insurrection quelled by the capture and execution of its leader. Tupac-Amard's brother, Diego Cristobal, continued the insurrection, and the viceroy offered, on 10 September, 1781, to abolish the Indian tribute and grant a general amnesty, which Diego Cristobal accepted. As some of the Indian chieftains continued the insurrection, Diego Cristobal, on the pretext that he was secretly in communication with the insurgents, was arrested, 27 February, 1783, carried as a prisoner to Cuzco, and, after a mock trial, sentenced to be tortured and hanged together with two other Indian chiefs and one woman. Jauregui's administration was not remarkable for any very beneficial measures, and he is justly accused of cruelty in the treatment of the Indian rebels; but, on the other hand, he was thoroughly honest, and, unlike other viceroys, died poor. His successor arrived early in 1784, and Jauregui delivered the government to him on 3 April. He died from the result of an accident, and was buried in the church of Santo Domingo.
