The town, so the story goes, owes its founding to a few over-heated dogs. These hounds were loved by a Franciscan friar, Juan de San Miguel, who started a mission in 1542 near an often-dry river 5km from the present town. One day the dogs wandered off from the mission; they were found reclining at the spring called El Chorro. The mission was moved to this superior site.
San Miguel was then central Mexico’s most northern Spanish settlement. Tarascan and Tlaxcalan allies of the Spanish were brought to help pacify the local Otomí and Chichimecs. San Miguel was barely surviving the fierce Chichimec resistance, until in 1555 a Spanish garrison was established to protect the new road from Mexico City to the silver center of Zacatecas. Spanish ranchers settled in the area and it grew into a thriving commercial center and home to some of Guanajuato’s wealthy silver barons.
San Miguel’s favorite son, Ignacio Allende, was born here in 1779. He became a fervent believer in the need for Mexican independence and was a leader of a Querétaro-based conspiracy that set December 8, 1810, as the date for an armed uprising. When the plan was discovered by the authorities in Querétaro on September 13, a messenger rushed to San Miguel and gave the news to Juan de Aldama, another conspirator. Aldama sped north to Dolores where, in the early hours of September 16, he found Allende at the house of the priest Miguel Hidalgo, also one of the coterie. A few hours later Hidalgo proclaimed rebellion from his church. After initial successes Allende, Hidalgo and other rebel leaders were captured in 1811 in Chihuahua. Allende was executed, but on independence in 1821 he was recognized as a martyr and in 1826 the town was renamed San Miguel de Allende.
The Escuela de Bellas Artes was founded in 1938 and the town started to take on its current character when David Alfaro Siqueiros began mural-painting courses that attracted artists of every persuasion. The Instituto Allende opened in 1951, also attracting foreign students. Many were American veterans (who could settle here under the GI Bill); an influx of artists has continued ever since.
