What if the Roman Empire had gone differently?

Augustus turns the exhausted Republic into a single Mediterranean state that lasts four centuries.

1. -509The Roman Republic, Italy stays a patchwork of small kingdoms; there is no republic, no Senate, no working model of citizenship for Europe to inherit.
2. 100Christianity spreads across Rome, The Roman world stays polytheist; the church that will hold medieval Europe together never forms.
3. 476The fall of Rome in the West, The Western Empire holds together; there are no barbarian kingdoms, no feudalism, no medieval Europe as we know it.
