Hadrian ( 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.
 
Hadrian's last years were marred by chronic illness. His marriage had been both unhappy and childless. In 138, he adopted Antoninus Pius and nominated him as a successor, on condition that Antoninus adopt Marcus Aurelius and Lucius Verus as his own heirs. Hadrian died the same year at Baiae, and Antoninus had him deified, despite opposition from the Senate. Later historians counted him as one of Rome's so-called "Five Good Emperors", and as a benevolent autocrat. His own Senate found him remote and authoritarian. He has been described as enigmatic and contradictory, with a capacity for both great personal generosity and extreme cruelty and driven by insatiable curiosity, conceit, and ambition.
