Hadrian was born to a Hispano-Roman family, probably in Italica (near Seville). His predecessor Trajan was a maternal cousin of Hadrian's father. Trajan never officially designated an heir, but according to his wife Pompeia Plotina, Trajan named Hadrian emperor immediately before his death. Trajan's wife and his friend Licinius Sura were well-disposed towards Hadrian, and he may well have owed his succession to them.
During his reign, Hadrian traveled to nearly every province of the empire. Hadrian sought to make Athens the cultural capital of the empire: he ordered the construction of many temples in the city.
Hadrian spent much of his time with the military. He usually wore military attire, and dined and slept amongst the soldiers. He ordered military training and drilling to be more rigorous and even made use of false reports of attack to keep the army alert. Despite his fondness for the army, there was little military activity throughout the empire while Hadrian reigned. After he became emperor, Hadrian withdrew from Trajan's conquests in Mesopotamia and Armenia, and even considered abandoning Dacia. Late in his reign, he stopped the Bar Kokhba revolt in Judaea, renaming the province Syria Palaestina.
In 136 an ailing Hadrian adopted Lucius Aelius as his heir, but he died suddenly two years later. In 138, Hadrian promised to adopt Antoninus Pius if he would in turn adopt Marcus Aurelius and Aelius' son Lucius Verus as his own eventual successors. Antoninus agreed, and soon afterward Hadrian died at his villa near Tibur.
