I want to know the answer to the following question:
When did the capital of the Roman Empire move to Constantinople?
All the background I'm provided with is that "The Hellenistic period may be seen to end either with the final conquest of the Greek heartlands by Rome in 146 BC following the Achean War, with the final defeat of the Ptolemaic Kingdom at the Battle of Actium in 31 BC, or even the move by Roman emperor Constantine the Great of the capital of the Roman Empire to Constantinople in 330 AD.". Is that enough to answer the question?
Answer: yes
