Hadrian

A Roman emperor who inaugurated a new military strategy for the empire: expansion and conquest were replaced by the consolidation of the borders and their defense.
His rule was characterized by tolerance, efficiency and splendor of the arts and philosophy. A cornerstone of Hadrian's policy was the idea of widening tolerance levels whenever possible. He promoted a legislative reform to lighten the position of slaves, who found themselves in inhuman situations when a crime occurred against the dominus. Even towards Christians he showed greater tolerance than his predecessors. 
To keep the troops' morale high and not let them lazy, Hadrian set up intense training shifts, personally inspecting the troops during his continuous travels. Since he was not inclined, since the days of the Dacian countryside, to distinguish himself for particular luxuries, he moved on horseback and shared in all the rough life of the legionaries. 
He attended and protected art, being himself an intellectual goal, lover of the figurative arts, poetry and literature. Architecture also fascinated him a lot and during his principality he worked to give a personal stylistic imprint to the buildings that were gradually built. For many historians he loved art perhaps even more than Nero, but unlike the latter he was never jealous of the different poets and artists, on the contrary, he wanted to learn and improve himself.
