I said almost 2000 years. It lasted from, officially, 476 BCE to 1453 CE, that’s 1929 years. Which is almost 2000 years, like I said.
When it comes to the West, the empire officially was made in 27 BCE with the first Emperor. I don’t think the republic really counted because all historical articles I can find say it lasted 503 years, not 1000. From 27 BCE to 476 CE.
Also, 753 BCE isn’t the Roman empire. It was the founding of Rome itself, meaning the city.
Ah I misread a bit of what you said. Thanks for the clarification.
Edit: Fixed the dates in the original post
