ORBEGOZO, Luis Jose (or-bay-go'-tho), Peru- vian soldier, b. in Chuquisongo, Huamachuco, 25 Aug., 1795 ; d. in Lima in 1847. Being destined by his parents for a literary career, he studied philosophy and physics in the College of San Car- los at Lima. After the death of his father he took charge of the property of his family and entered the militia as cadet of the regiment of cavalry of Trujillo, 27 Jan., 1815. When the army of Gen. San Martin arrived in Pisco in September, 1820, Trujillo, under the Marquis of Torre-Tagle, pro- nounced for independence on 29 Dec. of the same year, and Orbegozo was one of the most enthusias- tic promoters of the movement. As major of the regiment of Torre-Tagle he took part in the cam- paign of 1821 and 1822. He raised the " Invenci- bles de Trujillo " at his own expense and did good service during the campaign of the north, offering all his property to the patriotic junta, of which he was president, for the cause of liberty. Bolivar appointed him prefect of the Department of La Libertad, and in April, 1826, promoted him gen- eral of brigade. He served as commander of cav- alry in the campaign against Colombia, and was several times elected deputy to congress. The Na- tional convention chose him president of the re- public on 20 Dec, 1833, and when his predecessor, Gamarra [q. v.), tried to depose him in 1834 the at- tempt failed ; but, being of feeble character, Orbe- gozo accepted the intervention of Gen. Santa Cruz, president of Bolivia, and the Peru-Bolivian con- federation was formed in June, 1834. When the federation was dissolved by the forces of Chili at Yungay, 20 Jan., 1839, Orbegozo was exiled, but several years afterward he returned.
