Roman Decline
The Roman Empire, for many reasons, was in decline
from the late 2nd century C.E.
A shrinking population hindered army recruiting.
In political life, emperors were poor leaders.
Disputes over succession led to continual army intervention.
Tax revenues fell during hard  economic times.
Expansion of the empire ended after 180, thus closing the
sources of slave labor.
Environmental deterioration in North Africa diminished grain
supplies and tax revenues.
Recurring plagues further decimated the population and
disrupted economic life.
