Ancient Greece was a large area in the northeast of the Mediterranean Sea, where people spoke Greek. It was much bigger than the Greece we know today. It was the civilization of Greece, from the archaic period of the 8th/6th centuries BC to 146 BC. The period ended with the Roman conquest of Greece in the Battle of Corinth. For most of this time the Greeks did not have a single government or ruler.
