Ciudad Obregón

Ciudad Obregón is a city in southern Sonora. It is the state's second largest city after Hermosillo and serves as the municipal seat of Cajeme. As of 2020, the city has a population of 436,484. Ciudad Obregón is 530 km (330 mi) south of the state's northern border. The city, previously named Cajeme, takes its name from Mexican Revolutionary Álvaro Obregón, a native of nearby Huatabampo, Sonora. Álvaro Obregón became president of Mexico after the Revolution and initiated an "agricultural revolution" in the Yaqui Valley, introducing modern agricultural techniques and making this valley one of the most prosperous agricultural regions in the country. Renowned US agronomist Norman Borlaug, the architect of the "Green Revolution" worked here after successful developments in increasing the resistance of wheat. For his efforts he was later awarded the Nobel Prize. The origins of this city date back to the year 1906 when the company's rail track South Pacific Railway reached this area of the Yaqui Valley; this route, made it possible to incorporate with the Mayo Valley to the domestic and external market, attracting a wave of investors and settlers who brought out populations.
