The era that immediately followed the Iron Age was the Classical Era.
A Brief Timeline:
The Iron Age, spanning from approximately 1200 BC to 500 BC, gave way to the Classical Era around 500 BC. The Classical Era then extended until approximately 500 AD.
Here’s a simplified timeline to illustrate this:
- Bronze Age: ~5000 to 1200 BC
- Iron Age: ~1200 to 500 BC
- Classical Era: ~500 BC to 500 AD
- Medieval Era: ~500 AD to 1500 AD
Thus, the Classical Era marks the period immediately following the Iron Age.
