Hadrian was Roman emperor from 117 to 138. Hadrian was born in Italica, close to modern Seville in Spain, an Italic settlement in Hispania Baetica; his branch of the Aelia gens, the Aeli Hadriani, came from the town of Hadria in eastern Italy. He was a member of the Nerva-Antonine dynasty.

Italica was an ancient Roman city in Hispania; its site is close to the town of Santiponce in the province of Seville, Spain. It was founded in 206 BC by Roman general Scipio as a colonia for his Italic veterans and named after them. Italica later grew attracting new migrants from the Italian peninsula and also with the children of Roman soldiers and native women. Among the Italic settlers were a branch of the gens Ulpia from the Umbrian city of Tuder and a branch of the gens Aelia from the city of Hadria, either co-founders of the town or later migrants who arrived at an unknown time; the Ulpi Traiani and the Aelii Hadriani were the respective stirpes of the Roman emperors Trajan and Hadrian, both born in Italica.
