Short answers, pulled from the story.
Hispania Baetica was a Roman province established in 27 BC in the southwestern Iberian Peninsula, covering territory roughly matching modern Andalusia. It was named after the Baetis River, the Roman name for the Guadalquivir, whose fertile valley formed the heart of the province. Its neighbors were Lusitania to the west and Tarraconensis to the northeast.
Trajan and Hadrian, two consecutive Roman emperors, were both born in Itálica, a colonial town in Baetica. Trajan was the first emperor of provincial birth since Claudius, though his family was of Italic stock. Marcus Aurelius, though born in Rome, had ancestors from Ucubi, a Roman colony near Córdoba.
Seneca the Elder, a rhetorician, and his son Seneca the Younger, a Stoic philosopher, were both members of the Annaea family, a prominent Roman gens settled in Córdoba. A third member of the same family, the poet Lucan, wrote the Pharsalia, an epic on Caesar's civil war against Pompey the Great.
Baetica exported olive oil, wine, and the fermented fish sauce called garum, all staples of the Mediterranean diet. Olive oil from the province's vast plantations was shipped by sea to supply Roman legions in Germania, and Baetican amphoras have been found across the entire Western Roman Empire. The writer Columella, born in Gades (Cádiz), documented these agricultural traditions in a twelve-volume treatise on Roman farming.
As an administrative unit, Baetica ceased to exist after the Islamic invasion of 711 AD. Before that, the Vandals and Alans had passed through the province in the 5th century, and the Visigoths established a kingdom there. Even under Visigothic rule, Baetica remained one of the basic administrative divisions of Hispania.
The Turdetani were identified by the geographer Claudius Ptolemy as the dominant indigenous group in the western part of Baetica, occupying the valley of the Guadalquivir bordering Lusitania. After Rome took control of the peninsula, the Turdetani rose in revolt in 197 BC, prompting Cato the Elder to become consul in 195 BC and march south to suppress the uprising.
