1st millennium BC
millennium between 1000 BC and 1 BC
The 1st millennium BC, also known as the last millennium BC, was the period of time lasting from the years 1000 BC to 1 BC (10th to 1st centuries BC; in astronomy: JD 1356182.5 – 1721425.5). It encompasses the Iron Age in the Old World and sees the transition from the Ancient Near East to classical antiquity.
World population roughly doubled over the course of the millennium, from about 100 million to about 200–250 million after the birth of Jesus Christ and the establishment of the Julio-Claudian dynasty led by its founder Octavian.
Overview
The Neo-Assyrian Empire dominates the Near East in the early centuries of the millennium, supplanted by the Achaemenid Empire in the 6th century. Ancient Egypt is in decline, and falls to the Achaemenids in 525 BC.
In Greece, Classical Antiquity begins with the colonization of Magna Graecia and peaks with the conquest of the Achaemenids and the subsequent flourishing of Hellenistic civilization (4th to 2nd centuries).
The Roman Republic supplants the Etruscans and then the Carthaginians (5th to 3rd centuries). The close of the millennium sees the rise of the Roman Empire. The early Celtic culture dominate Central Europe while Northern Europe is in the Pre-Roman Iron Age. In East Africa, the Nubian Empire and Aksum arise.
In South Asia, the Vedic civilization gives rise to the Maurya Empire.

Why this record matters
A short description can identify a subject without explaining its stakes. For “1st millennium BC”, the useful work is to connect “millennium between 1000 BC and 1 BC” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q25716. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
