I was under the impression that the Roman Empire began in 753 B.C. and lasted until 476 A. D. That is slightly longer than 200 - 300 years.
Don’t confuse Roman civilization with the Roman Empire founded by Augustus, which did last 500 years, though it took only a couple centuries for it to become unrecognizable compared to its early years.
The Roman Republic may have started around 700 B.C. but the Empire didn’t officially start until Augustus in 27 B.C. and then you have to consider the Eastern Roman Empire which didn’t die until 1453 A.D.
“I was under the impression that the Roman Empire began in 753 B.C. and lasted until 476 A. D. That is slightly longer than 200 - 300 years.”
The Roman Kingdom started in 753 BC and ended in 509 BC, the “Republic” dated from 509 BC to 27 BC, the “Empire” dated to AD 476 and then morphed into the Byzantine Empire that lasted until 1453 AD.
A 2100 year run, sort of.
