The Municipality of Nogales is a municipality of northern Sonora state, in Northwestern Mexico. Geography The northern boundary of the Municipality is located along the U.S.—Mexico border. The county seat of the Municipality is the City of Nogales. The city is abutted on its north by the city of Nogales, Arizona, United States. History The independent Nogales Municipality, which included the town of Nogales, was established on July 11, 1884. The Nogales Municipality covers an area of 1,675 km². Nogales was declared a city within the Municipality on January 1, 1920. Escobarista Rebellion Early in March 1929, the Escobarista Rebellion exploded in Nogales, sponsored by Obregonistas, supporters of Mexican president Álvaro Obregón, who had been assassinated on July 17, 1928. General Manuel Aguirre, commanding the rebellious 64th Regiment, took power without firing a shot, causing federales from Naco to send a daily airplane to attack the rebels. It dropped a few bombs over Nogales without doing any damage, while the rebels fought back with machine guns from the roofs without doing any damage to the airplane. There was only one casualty, a woman who was scared by a bomb explosion and had a heart attack. That same month, a hooded man appeared at night driving a tank on Morley Street on the U.S. side, then entered Mexico to help the federales in Naco. It seems that the tank had been bought in 1927 for fighting the Yaquis, but U.S. officials prohibited it from leaving the U.S., and it had been kept in a warehouse in Nogales, Arizona.
