What historians have learnt about Iron Age Britain

Archaeologists and historians have learnt a lot about Iron Age Britain from the artefacts that have been found. They have used these artefacts alongside other sources, such as Roman writing about Iron Age Britain. By using these sources together they have been able to piece together what Iron Age Britain was like. Historians and archaeologists rarely rely on just one source, they often try to use lots together. A good explanation of what historians have learnt about Iron Age Britain will focus on how sources have been used.
