<P> The Roman conquest of Britain was a gradual process, beginning effectively in AD 43 under Emperor Claudius, whose general Aulus Plautius served as first governor of Roman Britain (Latin: Britannia). Great Britain had already frequently been the target of invasions, planned and actual, by forces of the Roman Republic and Roman Empire . In common with other regions on the edge of the empire, Britain had enjoyed diplomatic and trading links with the Romans in the century since Julius Caesar's expeditions in 55 and 54 BC, and Roman economic and cultural influence was a significant part of the British late pre-Roman Iron Age, especially in the south . </P> <P> Between 55 BC and the 40s AD, the status quo of tribute, hostages, and client states without direct military occupation, begun by Caesar's invasions of Britain, largely remained intact . Augustus prepared invasions in 34 BC, 27 BC and 25 BC . The first and third were called off due to revolts elsewhere in the empire, the second because the Britons seemed ready to come to terms . According to Augustus's Res Gestae, two British kings, Dubnovellaunus and Tincomarus, fled to Rome as suppliants during his reign, and Strabo's Geography, written during this period, says Britain paid more in customs and duties than could be raised by taxation if the island were conquered . </P>
