How many battles did Hadrian fight in?

Emperor Hadrian is not known for engaging in numerous battles; rather, he is noted for his diplomatic approach to governance and military strategy. His reign (117-138 AD) saw him focus on consolidating and securing the Roman Empire's borders rather than expanding them through warfare. The most significant military action during his reign was the suppression of a revolt in Judea, known as the Bar Kokhba revolt. Overall, Hadrian's emphasis was on stability and fortifying existing territories rather than waging frequent battles.
