Ancient Brit refers to the people who lived in Britain before the Roman invasion. The term encompasses three distinct groups: the Saxons, the Picts, and the Celts. The Saxons were a Germanic people who settled in Britain during the 5th century AD. The Picts were an indigenous people of Scotland who lived in the area from the late Iron Age until the 10th century AD. The Celts were a group of Indo-European peoples who inhabited much of Europe during the Iron Age and Roman period.
