Empire; and western rulers, convinced by their own propaganda
concerning the invincibility of the Germani and content with matters
as they stood, were unwilling to go out of their way to conquer them.
The ‘Guard on the Rhine’, which the imperial establishment sold so
successfully to contemporaries and to later historians, was an
artefact.238 If these ideas of the frontier as ‘stage-show’, and of the
stage-show as both justiWcation and support of the imperial order are
acceptable,239 they raise other issues. For example, it is usually
understood that, from the third century, imperial power was divided
because the Empire, under pressure, needed armies led by emperors
on most of its frontiers. An alternative interpretation is that, even
from the third century, imperial collegiality became the norm
because eVective control of the totality of the frontier armies upon
which imperial political power rested had become a rare skill.
Lieutenant Caesares and Augusti were despatched to the main
political power centres to maintain the loyalty of the troops, where
necessary by leading them to victory against neighbouring peoples.
However, on the Rhine an underworked army was still a dangerous
army, which may explain the relative frequency of usurpations in the
west in the fourth century.240
This returns us to the two questions posed earlier in this chapter:
how did the Franks, in conquering the Alamanni, succeed where
Rome had failed; and how did they reverse the Xow of conquest
from east-to-west to west-to-east? The answer is that Clovis and his
successors, as relative latecomers, not the children of ‘Mischzivilisa-
tion’, were not subject to established imperial preconceptions. Free
from traditional Roman fears of Brennus, the Cimbri and Arminius,
238 Here I come very close to GoVart’s view that the imperial frontier was generally
the cause of imperial insecurity, and that the frontier therefore justiWed the imperial
regime by pointing up or creating something which the inhabitants of the Empire
could be told they needed to be defended against (1980: 30; 1989: 6). On the other
hand, unlike GoVart (1989: 7), I doubt very much whether, in the west at least, there
was ever a threat big enough to justify the size of garrison that was kept on the
frontier.
239 They appear to be gaining some currency: see Pohl (2000: 35): ‘Fu
