The period of ~1000 BC was solidly Bronze age, before the classical era or antiquity (~500 BC), before the Roman Empire, before the fall of the Roman Empire leading to the Dark Ages.
"The "Dark Ages" is a historical periodization traditionally referring to the Middle Ages (c. 5thβ15th century) that asserts that a demographic, cultural, and economic deterioration occurred in Western Europe following the decline of the Roman Empire."
