<P> Julius Caesar invaded Britain in 55 and 54 BC as part of his Gallic Wars . The Britons had been overrun or culturally assimilated by other Celtic tribes during the British Iron Age and had been aiding Caesar 's enemies . He received tribute , installed a friendly king over the Trinovantes , and returned to Gaul . Planned invasions under Augustus were called off in 34 , 27 , and 25 BC . In 40 AD , Caligula assembled 200,000 men at the Channel , only to have them gather seashells . Three years later , Claudius directed four legions to invade Britain and restore an exiled king over the Atrebates . The Romans defeated the Catuvellauni , and then organized their conquests as the Province of Britain ( Latin : Provincia Britannia ) . By the year 47 , the Romans held the lands southeast of the Fosse Way . Control over Wales was delayed by reverses and the effects of Boudica 's uprising , but the Romans expanded steadily northward . </P>
