Why is the Iron Age called the Iron Age?
The organization of history into the Three-Age System was proposed originally by a 19th-century Danish archaeologist Christian Thomsen. While Thomsen was organizing artifacts for the National Museum of Denmark, Thomsen suggested that they be categorized based on an assumption of a progression in human technology. The Three-Age System, the Stone, Bronze, and Iron ages, refers to the type of material used to make tools and weapons. The Iron Age would be the time in history when a civilization largely replaced the use of bronze with the use of iron. The first organized use of Iron to form tools and weapons has been traced to southwestern Asia around 2000 B.C.E.
