Final answer:
The emperors used trade policies to stimulate economic growth and inspire loyalty among the Roman people.
Step-by-step explanation:
The emperors used the economic system to inspire loyalty among the Roman people by focusing on trade policies to stimulate economic growth.
By promoting trade and improving the economy, the emperors were able to ensure that the Roman people had access to wealth and prosperity. This created a sense of loyalty and support for the emperors, as the people benefited from their economic policies.
For example, the conquest of Egypt, which was Rome's primary supplier of grain, greatly expanded the empire's grain supply and supported economic growth. Additionally, the emperors financed the military through the economic system, which further contributed to the empire's prosperity and inspired loyalty.
