Iceni
The Iceni ( eye-SEEN-eye, Classical Latin: [ɪˈkeːniː]) or Eceni were an ancient tribe of eastern Britain during the Iron Age and early Roman era. Their territory included present-day Norfolk and parts of Suffolk and Cambridgeshire, and bordered the area of the Corieltauvi to the west, and the Catuvellauni and Trinovantes to the south. In the Roman period, their capital was Venta Icenorum at modern-day Caistor St Edmund. Julius Caesar does not mention the Iceni in his account of his invasions of Britain in 55 and 54 BC, though they may be related to the Cenimagni, whom Caesar notes as living north of the River Thames at that time. The Iceni were a significant power in eastern Britain during Claudius' conquest of Britain in AD 43, following which they allied with Rome.
