The "Grito" of independence.
It takes place every year on the night of September 15, in memory of the harangue made by the priest Miguel Hidalgo, when he called the Mexicans to take up arms. This act began the Mexican War of Independence, as well as the fight against New Spain, on the morning of September 16, 1810, when the priest rang the bells of the Parroquia del Pueblo de Dolores, in Dolores Hidalgo, Guanajuato.
Today it is a ceremony headed by the presidents and governors of Mexico who represent the "grito" in the public squares of Mexico.
Within the message of the "grito", "vivas" are sung for each of the heroes of the country, the people present on the square respond in the same way with a "viva."
