The Belgae had made their way across the English Channel into southern Britain in Caesar's time. Caesar asserts they had first crossed the channel as raiders, only later establishing themselves on the island. The precise extent of their conquests is unknown. After the Roman conquest of Britain, the civitas of the Belgae was bordered to the north by the British Atrebates, who were also a Belgic tribe, and to the east by the Regni, who were probably linked to the Belgae as well.
