There were political and military difficulties, as well. It didn't help matters that political amateurs were in control of Rome in the years leading up to its fall. Army generals dominated the emperorship, and corruption was rampant. Over time, the military was transformed into a mercenary army with no real loyalty to Rome. As money grew tight, the government hired the cheaper and less reliable Germanic soldiers to fight in Roman armies. By the end, these armies were defending Rome against their fellow Germanic tribesmen. Under these circumstances, the sack of Rome came as no surprise.
When the Han Dynasty collapsed in 220 CE, no one was powerful enough to reunify China under a single emperor. The result was the period of the Three Kingdoms, which lasted until 280 CE, when the Jin Dynasty took over. These three kingdoms, Wei, Shu, and Wu, battled for control in a long series of wars. This was one of the bloodiest times in Chinese history—according to census data, the population decreased from 50 million to 16 million—but it also has long been romanticized in East Asian cultures and remembered as a time of chivalry and honor. It has been celebrated and popularized in operas, folk stories, and novels, and in more recent times, films, television, and video games.
