When was the nathional them of Mexico declared threr nathion athom?

Answer 1

The official name is Mexican National Anthem (in Spanish: Himno Nacional Mexicano). The lyrics were written by Mexican poet Francisco Gonzalez Bocanegra in 1853. In 1854, Catalan composer Jaime Nunó composed the music which acompanies the anthem. Unofficialy, the anthem is sometimes called "Mexicanos, al grito de guerra" (Spanish for "Mexicans, at the cry of war") which is also the first line of the chorus.

An urban legend about the copyright status of the anthem states that it is owned by a United States firm. This however, is not the case. United States copyright law declares the Mexican anthem to be in the public domain inside the United States, since both the lyrics and music were published before 1909.
