Army of the Three Guarantees
The Army of the Three Guarantees (Spanish: Ejército Trigarante or Ejercito de las Tres Garantías ) was the first army of independent Mexico. It emerged from the union of royalist and revolutionary troops in the Mexican War of Independence and is the forerunner of today's Mexican Army .
Its creation was decided on February 24, 1821 in the Iguala plan . It was named after the three guarantees set out in the Iguala Plan that it was supposed to defend: religion, independence and unity. On the same day, the tailor José Magdaleno Ocampo presented the flag ordered by the army leader, Agustín de Iturbide . This is considered to be the forerunner of today's flag of Mexico , which is why this date is celebrated today as Día de la Bandera .
A number of insurgents, but also royalist military, joined the army. The new viceroy Juan O'Donojú met with Itúrbide in Cordoba on August 24, 1821 , where they signed the treaty of the same name , which recognized the independence of Mexico.
On September 27, 1821, the army marched into Mexico City from various directions .
After Itúrbides gained independence and acceded to the throne as Emperor of Mexico , the army became the regular army of Mexico.
