The fall of the Roman Empire is often presented as symbolic of the slow but steady decline of the western world today, and it's true, this comparison might be more accurate than many people realize. The disastrous collapse which escalated over the course of the 5th century was driven by economic crisis, a split of the empire into eastern and western halves, government reliance on foreign mercenaries for security, uncontrolled mass immigration, and ultimately, barbarian invasion.

When the western empire failed, Rome was plundered and centuries of human innovation and progress were lost in the flames. It's an element that modern historians often gloss over – Each time the west has fallen, incredible knowledge that took generations to discover was dispersed into the ether. Each time, the human species was set back for centuries.

Many lives were sacrificed and ancient cities were destroyed, but the loss of time is perhaps the greatest tragedy of all. It took another 400 years for the western world to reconstitute under Christian rule, but barbarians attacked again in the form of Muslim hordes in the 9th century. It's almost as if the grasping, predatory hands of useless ravagers are always lurking in the shadows, waiting for the west to rise from the ashes.

History is, of course, nuanced and complex, but some patterns are patently obvious and the attempts to sack Rome, Europe and greater Christendom repeated regularly over the course of a thousand years. Western civilization endures, succeeds, creates wonders, creates wealth and advances human invention. Then, the third world invades in an effort to strip whatever wealth was amassed.

There have been other civilizations, or attempts at civilizations beyond the west which suffered similar fates. The fall of the Bronze Age empires is a perfect example; a calamity of human history very similar to the fall of Rome, if not more mysterious. There was the collapse of China's Han Dynasty in the 3rd century due to corruption, rebellion and foreign invasion by Mongolian tribes. The collapse of the Gupta Empire in India, triggered by Hunnic barbarian incursions, etc.
