REYNOSA

city, north-central Tamaulipas estado (state), northeastern Mexico. It lies just across the Rio Grande (Ro Bravo del Norte) from Hidalgo, Texas, U.S. Reynosa was founded in 1749 as part of a program to develop the Mexican interior. Subject to repeated floods, it was moved to higher ground, 300 feet (90 m) above sea level, in 1802. Its inhabitants were among the first to rebel against Spanish rule in 1810; they also participated in the Revolution of 1910. The state congress declared Reynosa a city in 1926. Its economy, based principally on cattle raising, was improved considerably with the introduction of irrigation in 1935, improving pasturage and greatly expanding production of cotton, sugarcane, corn (maize), and other crops. The city's oil refineries and petrochemical plants serve the nearby fields, and pipelines carry natural gas to the U.S. and to Monterrey, 140 mi (225 km) to the southwest. It also has cotton mills, distilleries, sawmills, brick plants, and other industries. Reynosa is also a port of entry and a transportation centre, accessible by highway, railroad, and air from major cities in southern Texas and northeastern Mexico. Pop. (1980) 240,000.
