Published by Travis Hayman (A0.951591). The Mexican National Anthem (Spanish: Himno Nacional Mexicano), also known by its incipit Mexicans, at the cry of war, is the national anthem of Mexico. The anthem was first used in 1854. The lyrics of the national anthem, which allude to historical Mexican military victories in the heat of battle and including cries of defending the homeland, were composed by poet Francisco González Bocanegra after a Federal contest in 1853. Later, in 1854, he asked Jaime Nunó to compose the music which now accompanies González's poem.
