Tonus Mejia, a Mexican soldier, born about 1812, executed in Queretaro, June 19, 1867. lb; was of pure Indian blood and of humble origin; but he acquired such influence among the natives of the Sierra Gorda of Guanajuato as to be styled the "king of the mountains," and for nearly 20 years he was conspicuous in the Mexican revolutions. He bore an honor-able part in the war with the United States in 1847-8, and in 1840 was sent to suppress an insurrection in his native state, headed by Mar-quez. In 1855 he "pronounced" against Co-monfort, but soon submitted. The next year he headed an insurrection in the interest of the church party, and took Queretaro. In 1857 he was second in command of the revolutionary forces in San Luis Potosi, but was defeated in several actions, and obliged to capitulate. In 1858 he drove Juarez and his government successively from Queretaro and Guanajuato, and during the ensuing three years maintained the Sierra for Zuloaga and Miramon. After the triumph of Juarez in 1861, Mejia still kept up a guerilla warfare for a considerable time. He was a firm supporter of Maximilian, from whom he received high honors.

Captured with him at Queretaro, May 15, 1867, he was tried, condemned, and executed.
