Early on the morning of September 16, 1810, Father Miguel Hidalgo y Costilla summoned the largely Indian and mestizo congregation of his small Dolores parish church and urged them to take up arms and fight for Mexico's independence from Spain. His El Grito de Dolores, or Cry of Dolores, which was spoken—not written—is commemorated on September 16 as Mexican Independence Day.
Father Hidalgo was born into a moderately wealthy family in the city of Guanajuato, northwest of Mexico City, in 1753. He attended the Jesuit College of San Francisco Javier, received a bachelor's degree from the University of Mexico in 1774, and was ordained into the priesthood in 1778. He soon earned the enmity of the authorities, however, by openly challenging both church doctrine and aspects of Spanish rule by developing Mexican agriculture and industry.
In 1803, Hidalgo accepted the curacy of the small parish of Dolores, not far from his native city of Guanajuato. Between 1803 and 1810, he directed most of his energy to improving the economic prospects of his parishioners. He also joined the Academia Literaria, a committee seeking Mexico’s independence from Spain.
