Depicts the seal of the United Mexican States.

The Seal of the United Mexican States is a modified version of the national coat of arms, with the addition of the full official name of the country Estados Unidos Mexicanos, in a semi-circular accommodation in the upper part of the seal. Current and past Mexican peso coinage have had the seal engraved on the obverse of all denominations.

The coat of arms depicts a Mexican golden eagle perched on a prickly pear cactus devouring a rattlesnake. To the people of Tenochtitlan this would have strong religious connotations, but to the Europeans, it would come to symbolize the triumph of good over evil (with the snake sometimes representative of the serpent in the Garden of Eden).

IIgnacio Allende (1769-1811) was a captain of the Spanish Army in Mexico who came to sympathize with the Mexican independence movement. He attended the secret meetings organized by Josefa Ortiz de Domínguez, where the possibility of an independent New Spain was discussed. He fought along with Miguel Hidalgo y Costilla in the first stage of the struggle, eventually succeeding him in leadership of the rebellion. Allende was captured by Spanish colonial authorities while he was in Chihuahua and executed for treason.
