The Alamo area was originally known as “Agostadero de Alamo” (Pasture of the Cottonwood Trees). A part of Mexico, it was administered from Reynosa, and was rich in wildlife. Karankawa Indians lived here and in the 1700s Spanish land grant recipients started cattle ranching. The land was cleared in the 1920s and Alamo was incorporated in 1924. Thousands of newcomers moved in, mostly farmers from the Midwest and Mexico. Many Alamo families have lived here for three generations. The mix of immigrants from north and south of the Rio Grande has created a unique, enjoyable blend of customs and cultures.
