Hadrian
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.
