Hadrian (/ˈheɪdriən/ HAY-dree-ən; born Publius Aelius Hadrianus, 24 January 76 – 10 July 138) was Roman emperor from 117 to 138. Hadrian was born in Italica, in the present-day Andalusian province of Seville in southern Spain, an Italic settlement in Hispania Baetica; his gens Aelia came from the town of Hadria in eastern Italy. He was a member of the Nerva–Antonine dynasty.

Early in his political career, Hadrian married Vibia Sabina, grandniece of the ruling emperor, Trajan, and his second cousin once removed. The marriage and Hadrian's later succession as emperor were probably promoted by Trajan's wife Pompeia Plotina. Soon after his own succession, Hadrian had four leading senators unlawfully put to death, probably because they seemed to threaten the security of his reign; this earned him the senate's lifelong enmity. He earned further disapproval by abandoning Trajan's expansionist policies and territorial gains in Mesopotamia, Assyria, Armenia, and parts of Dacia. Hadrian preferred to invest in the development of stable, defensible borders and the unification of the Roman empire's disparate peoples and subjects. He was a promoter of philhellenism.

Italica (Spanish: Itálica) 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.

According to some authors, Italica was also the birthplace of Theodosius.
