The Turdetani people occupied the fertile valley of the Guadalquivir River in the western part of what became Baetica. Claudius Ptolemy described them as powerful indigenes who bordered Lusitania to the west.
Hispania Baetica submitted to Rome in 206 BC and later became a senatorial province in 14 BC. Colonia Patricia Corduba served as its capital founded in 169 BC under this administrative structure.
Trajan emerged from Itálica as the first emperor since Claudius to be of provincial birth despite Italic stock origins. His kinsman Hadrian also came from that same town during his reign from 117 to 138 AD while Marcus Aurelius traced ancestry back to Ucubi near Córdoba.
Baetica shipped vast quantities of olive oil from its coastal ports to supply Roman legions in Germania. The province exported wine alongside fermented fish sauce known as garum which formed part of the western Mediterranean trade economy even before submission to Rome in 206 BC.
Baetica divided into four conventūs serving as territorial judicial circuits under proconsul oversight including Gaditanus Cordubensis Astigitanus and Hispalensis.
