What are the differences between early iron age and late iron age?

The Early Iron Age, roughly spanning from 1200 to 600 BCE, is characterized by the introduction of iron Metallurgy, leading to advancements in tools and weapons, as well as the establishment of early state formations and trade networks. In contrast, the Late Iron Age, from around 600 BCE to the Roman conquest, sees increased complexity in social structures, urbanization, and more extensive trade networks, along with the emergence of powerful kingdoms and empires. Additionally, cultural developments, including art and writing, become more prominent in the Late Iron Age, reflecting broader societal changes.
