The answer is:
arminius -lrb- 18/17 bc -- ad 21 -rrb- was a chieftain of the germanic cherusci who defeated a roman army in the battle of the teutoburg forest in 9 ad .arminius 's influence held an allied coalition of germanic tribes together in opposition to the romans but after defeats by the roman general germanicus , nephew of the emperor tiberius , his influence waned , and arminius was assassinated on the orders of rival germanic chiefs .arminius 's victory against the roman legions in the teutoburg forest had a far-reaching effect on the subsequent history of both the ancient germanic peoples and on the roman empire .the romans were to make no more concerted attempts to conquer and permanently hold germania beyond the river rhine .modern historians have regarded arminius ' victory as '' rome 's greatest defeat '' and one of the most decisive battles in history .during the unification of germany in the 19th century , arminius became hailed by nationalists as a symbol of german unity and freedom .following world war ii however , information about arminius and his victory was omitted from the german textbooks , and many modern germans do n't know about arminius .the 2,000 year anniversary of the battle was not commemorated by the german government .according to der spiegel '' the old nationalism has been replaced by an easy-going patriotism that mainly manifests itself at sporting events like the soccer world cup .
