The Iron Age Celts lived in Britain and Ireland from 750BC to 43AD. They were part of tribes that often fought with neighboring tribes. The Celts were skilled craftsmen who worked with iron to create weapons and household objects. They were also fierce warriors who painted themselves with woad and fought naked or with shields, spears, and daggers. The Celts lived in roundhouses and were mainly farmers who grew crops and hunted animals. They wore brightly colored woolen clothes and enjoyed decorating with gold, silver, and bronze jewelry. The Romans invaded Britain in 43AD and were able to conquer the Celts who were disorganized compared to the disciplined Romans.
