27 BCE: Roman Empire established
After which:
410 CE: Alaric seized Rome
And finally:
476 CE: Odoacer sacked Rome
You can figure out the chronological order by looking if it has either CE or BCE - BCE is before Christ and CE is after Christ. When counting from BCE it goes from higher numbers towards zero. When counting from CE it goes from zero to higher numbers again.
