The Celts were loosely connected groups of people who lived across Europe during the Iron Age. They spoke similar languages and shared cultural and religious practices. The Celts lived in scattered farming villages and hill forts, building houses out of materials like wood, stone, and mud. They wore colorful woven clothes and ate a variety of plants and animals. The Celts had many gods and goddesses and were led spiritually by druids. They believed in an afterlife and buried the dead with possessions. Celtic society was divided into social classes including warriors and intellectuals.
