Hadrian ruled the Roman empire between 117 and 138 CE. He inherited a prosperous empire from his adoptive father Trajan and focus on increasing the stability of the state and the well-being of its citizens.
While he wasn't a famous general, (although he still managed to suppress the Bar Kokhba revolt in Judea) he cemented his place in Roman history as a builder. Among the greatest memories of his age, one can count his villa in Tivoli, his mausoleum (known as Castel Sant'Angelo) and the Pantheon. Let us not forget his contribution in various provinces - from Hadrian's wall in Britain to his library in Athens. His fascination by Greeks became well-known, to the extent that he brought a beard (in the style of Greek philosophers) bac to fashion.
He wasn't a great lover of women, in fact, his relationship with a young Greek called Antinous became his most famous love story. He remained childless and adopted Antoninus Pius as his successor.
