Hadrian and the military

Hadrian and the military

Despite his own great stature as a military administrator, Hadrian's reign was marked by a general lack of major military conflicts, apart from the Second Roman-Jewish War. He surrendered Trajan's conquests in Mesopotamia, considering them to be indefensible. There was almost a war with Parthia around 121, but the threat was averted when Hadrian succeeded in negotiating a peace.

The peace policy was strengthened by the erection of permanent fortifications along the empire's borders (limites, sl. limes). The most famous of these is the massive Hadrian's Wall in Great Britain, and the Danube and Rhine borders were strengthened with a series of mostly wooden fortifications, forts, outposts and watchtowers, the latter specifically improving communications and local area security. To maintain morale and keep the troops from getting restive, Hadrian established intensive drill routines, and personally inspected the armies. Although his coins showed military images almost as often as peaceful ones, Hadrian's policy was peace through strength, even threat.
