in isolating the Paisa population until the end of the nineteenth century and the area's industrial revolution. Extremadura The ancestors of the Paisa are primarily Spanish immigrants from Extremadura, Spain (sixteenth century). The first colonizers were Extremaduran like Gaspar de Rodas of Trujillo, who was the first colonial governor of the region. Several towns, cities and places in the Paisa Region are also Extremaduran: Medellín for Medellín of Badajoz; Cáceres for the Province of Cáceres; Valdivia for conqueror Pedro de Valdivia. Andalusia Some conquerors from Andalusia like Marshall Jorge Robledo of Jaén, came also with the Extremadurans during the sixteenth century. However, during the seventeenth century a group of Andalusian migrants is said to have settled the region. Basque people The presence of Basque ancestry in the Paisa Region is exhibited by the proliferation of Basque surnames. Some scholars point out that this may be one of the regions of Hispanic America with the greatest concentration of ancestry from the Iberian region. The Basques arrived in Antioquia during the seventeenth century. The use of Basque language (Euskera) terminology in the present territory of Colombia goes back to the early exploration which occurred in 1499, during the third voyage of Columbus. It is said that from that time the territory experienced a strong influx of Basques including prominent figures such as the pilot and geographer Juan de la Cosa, nicknamed "El Vizcaino" (although some reputable sources claim that he was not a native of the Basque Country, but was instead born in Santoña, Cantabria). Thereafter, the Basques began to come regularly and distributed throughout the country. Due to this presence, the Colombian department of Antioquia has been considered a major point of Basque-Navarre immigration. This occurred mainly during the colonial era, when thousands of Basques migrated to be linked to the Spanish colonization companies. To people interested in investigating the presence of Euskal Herria in the department of Antioquia, one of the questions that troubles them relates to the use and retention of the Basque language in the department. It is estimated that for Antioquia, a region where tens of thousands of Spaniards arrived, of which a good portion were Basque, limited aspects of the Basque language were brought over. It has been difficult to track the use of Euskera in Antioquia and Colombia because the Basque language was always an outcast, which apparently left no written evidence in Antioquia. This
