Some 250 years after its first publication, Gibbon's Decline and Fall is still regarded as one of the greatest histories in Western literature. He reports on more than 1,000 years of an empire which extended from the most northern and western parts of Europe to deep into Asia and Africa and covers not only events but also the cultural and religious developments that effected change during that time. In Volume III (XXVII-XXXVI), Gibbon charts the fall of the Western empire. Starting with the reign of Emperor Gratian (d. 383) his survey moves to political and religious issues in the East and West before covering the increasing military power of the Barbarians. Occasionally a great Roman general emerges to stem the tide, but internecine power struggles see the Western empire weakened, until Gaul, Britain, Spain and other territories find themselves, as the 5th century advances, unable to rely on Rome for defense.
