In 1905 the town reached over 5,000 inhabitants, but the population then gradually declined. Too many population for a backward economic and especially poorly organized. Since the 1920s appears migration toward the near zones or Badajoz, Seville and Madrid, which intensified from the 1950s to the 1970s, when six in ten people emigrated, also toward other regions like Barcelone or Valencia. Remittances from emigrants became the main source of wealth throughout the century. Another event within the century was the Spanish Civil War. Franco's troops entered with little resistance into a village terrified by the excesses of the republicans such as the confiscation of food or the burning of Churches in nearby towns. But, on the other hand, the 1940s were years of repression too by the Guardia Civil, with rebels in near mountains and crags to Cabeza La Vaca until well into the 1950s.
