Alamán, Lucas (lo͞o`käs älämän`), 1792–1853, Mexican historian and statesman. As deputy to the Spanish Cortes, he failed to win a hearing for the insurgents in Mexico. Returning to Mexico, he held several public offices and was twice minister of foreign affairs in the government after the fall of Agustin de Iturbide. Alamán founded the Archivo General and the National Museum, in Mexico City. He is chiefly remembered for his comprehensive history of Mexico, Historia de Méjico (5 vol., 1849–52).
