In 184 AD, the Roman Empire was under the rule of Emperor Commodus, who became emperor in 180 AD. This period was marked by political instability and increasing corruption within the government. Commodus was known for his erratic behavior and extravagant lifestyle, which contributed to the decline of the empire's stability. During this time, the Han Dynasty in China was also experiencing challenges. The reign of Emperor Ling saw internal strife and the rise of powerful eunuchs in the court. These issues would eventually lead to significant changes in the political landscape of China, setting the stage for future conflicts.
