Mariano Arista, a Mexican general, born in the state of San Luis Potosi, Mexico, July 16, 1802, died in Spain, Aug. 9,1855. Having distinguished himself in the successive wars which established first the independence of Mexico and afterward the republican form of government, he attained a high position in the Mexican army, and in 1836 was second in command to Santa Anna, then general in chief. By the revolutions which continually agitated Mexico he was twice deprived of his command; but his military knowledge was indispensable to every dominant party, and he was quickly restored and promoted. In the war with the United States he commanded at Palo Alto and Resaca de la Palma; and after its close was appointed in June, 1848, minister of war under President Herrera. In 1850 he was elected president of Mexico, but resigned Jan. 6, 1853, and retired to his farm, and was banished soon afterward.
