thanks so much for replying....
I know some little information about this topic, that's why i 'm seeking more...
I've learnt that its split into eastern and western empires governed by separate emperors had caused Rome to fall. The eastern half became the Byzantine Empire, with its capital at Constantinople (modern Istanbul). The western half remained centered in Italy. The fall lastes more than a century.
And I believe, Comet, that there are more than one reason behind this decline: such as Christianity, decadence, lead, monetary trouble, and military problems.
And this is the source of my words.. http://egyptopia.com/The+Decline_30_...15_766_en.html
