Reynosa was founded on 14 March 1749 by Carlos Cantú under the command of José de Escandón y Helguera the Count of Sierra Gorda, and 279 Habitats. But due to flooding in the area on the 4 July 1802, they decided to move 5 miles to the east keeping the same margin between them and the Rio Grande (Río Bravo for México). It was not until 1926 that the state government recognized Reynosa as a city.
Reynosa today is the location of several satellite U.S. Companies doing business to take advantage of low labor rates and sparse benefits.
