Discuss the ways that Rome maintained the stability of its vast empire

What will be an ideal response?

The Romans enfranchised those local populations that they found to be sufficiently loyal. They also improved local infrastructure which brought tangible benefits to subject populations. Soldiers were given plots of land which allowed for high living standards which in turn increased their loyalty to Rome and discouraged rebellions. Augustus encouraged this stability by promoting lower born subjects to positions of prominence and erasing the distinction between equites and patrician. This increased the loyalty of his subjects and likely nourished the hope of upward mobility for the lower classes.
