Eastern Han Dynasty

The Eastern Han Dynasty was founded after by Emperor Guangwu of Han in 25 CE, following the overthrow of Wang Mang's Xin Dynasty. Guangwu established the Imperial Capital in the modern city of Luoyang, Henan Province. Though it started off on a high note, with the height of the Empire coming in the reign of Emperor Zhang (75-88 CE), the Eastern Han was founded on much weaker foundations than the Western Han. Emperor Guangwu was forced to rely on the big landholding families in order to gain power - and he was largely unable to centralise power back to the extent that it had been under the Western Han Empire.

Additionally, following the reign of Emperor Zhang, the Royal Family increasingly fell under the influence of the Eunuch Faction. Though eunuchs had been present in the Western Han Dynasty (Sima Qian, the author of Records of the Grand Historian was a eunuch), they began to hold larger and larger influence, in the same way that the families of Emperors' wives were able to acquire power over the course of the Western Han Dynasty. In fact, the eunuchs were often in conflict with the families of these great families, and over time the power struggles came to dominate the internal affairs of the Imperial Court.

In terms of foreign policy, the Eastern Han were able to largely maintain their holdings in northern Korea and Vietnam, along with finally ending the Xiongnu threat in the north through a series of military campaigns. Han power and culture were projected along the Silk Road, reaching as far as Central Asia and maintaining contact with the Parthian Empire of modern day Near Asia, along with civilisations in India. In CE 97, the Han organised an attempt at reaching Da Qin (Rome), but reportedly got as far as the Southern Mediterranean before turning back; in CE 166 a Roman embassy from Emperor Marcus Aurelius (likely merchants) did reach the court of Emperor Huan, though any interactions between the two great Empires on opposite ends of the Eurasian continent did not get more intricate than that.

Despite these foreign policy successes, the corruption in internal matters eventually weakened the central authority of the Imperial Court greatly. The eunuch faction's propensity to auction off court positions caused offense with the bureaucrats, who were further alienated when Emperor Huan (125-144 CE) sided with the eunuchs.

By the time the Yellow Turban and Five Pecks of Rice (I swear I am not making these names up) Rebellions flared up in 184 CE, the power of the central government was weak enough that the courts were forced to rely on regional strongmen to raise forces to combat these rebellions - a decision that saw warlords springing up all over the country, and leading to the Three Kingdoms era.
