Key Facts

  1. The Iron Age began around 1200 BCE in the Near East after the Late Bronze Age collapse, though dates vary by region.
  2. Iron ore was more abundant than copper and tin, making iron tools and weapons cheaper to produce once smelting techniques were mastered.
  3. Major Iron Age civilizations included the Assyrians, Phoenicians, Persians, Greeks, Romans, and Celts.
  4. The Iron Age saw the spread of alphabetic writing systems, such as the Phoenician alphabet, which influenced Greek and Latin scripts.
  5. In Northern Europe, the Iron Age is often divided into the Hallstatt culture (c. 800–450 BCE) and La Tène culture (c. 450 BCE–1 CE), associated with early Celtic peoples.
