Diez y Seis de Septiembre or the 16th of September celebrates Mexico's independence from Spain.
In the early hours of September 16,1810, Father Miguel Hidalgo, accompanied by several others, rang the bell of his little church in Guanajuato, and gave the cry—El Grito de Dolores! ("Mexicanos, Viva Mexico!"). A call to fight for liberty. This was the beginning of the Independence War, which lasted 10 years.
