One major similarity between the fall of the Han Dynasty, Gupta Empire, and Roman Empire is the presence of external threats and invasions.
In all three cases, the empires faced attacks from nomadic tribes and foreign invaders. For example, the fall of the Han Dynasty in China was partly due to the constant attacks from the Xiongnu and other nomadic tribes from the north.
Similarly, the Gupta Empire in India faced invasions from the White Huns, while the Roman Empire had to deal with the Visigoths, Vandals, and other Germanic tribes. These invasions weakened the empires, leading to their eventual downfall.
