Answer:
True
Step-by-step explanation:
Hadrian was a Roman emperor who was not greatly interested in the expansion of the empire. He abandoned the territories that Trajan has conquered in areas such as Mesopotamia, Assyria, Armenia and parts of Dacia. Instead, he was interested in creating strong borders and stability. One of the borders he set was at the Rhine River and Danube River, representing the northern boundary of the empire.
