Miguel Hidalgo y Costilla, was a Mexican Roman Catholic priest and a leader of the Mexican War of Independence.

He was a professor at the Colegio de San Nicolás Obispo in Valladolid and was ousted in 1792. He served in a church in Colima and then in Dolores, Dias. After his arrival, he was shocked by the rich soil he had found. He tried to help the poor by showing them how to grow olives and grapes, but in Mexico, growing these crops was discouraged or prohibited by the authorities due to Spanish imports of the items. In 1810 he gave the famous speech, "The Cry of Dolores", calling upon the people to protect the interest of their King Fernando VII (held captive by Napoleon) by revolting against the European-born Spaniards who had overthrown the Spanish Viceroy.

He marched across Mexico and gathered an army of nearly 90,000 poor farmers and Mexican civilians who attacked and killed both Spanish Peninsulares and Criollo elites, even though Hidalgo's troops lacked training and were poorly armed. These troops ran into an army of 6,000 well-trained and armed Spanish troops; most of Hidalgo's troops fled or were killed at the Battle of Calderón Bridge.

Besides being a revolutionary, Hidalgo was also a philosopher, see https://plato.stanford.edu/entries/philosophy-mexico/: "Several Mexican thinkers appealed to scholastic political philosophy to answer affirmatively to the question, and also—though not always explicitly— to the philosophy of the Enlightenment. Such was the case of Miguel Hidalgo (1753–1811), father of Mexican Independence. Hidalgo’s predilection for French ideas was well known, but he was also known for his opposition to Aristotelian-based scholastic theology displayed in his Disertación sobre el verdadero método de estudiar teología escolástica (1784)."
