Luoyang was the Eastern Han capital. After Emperor Ling died, He Jin, the eunuchs, Dong Zhuo, and Yuan Shao collided here. Once the eastern governors rose, Dong Zhuo could not hold the east. In 190 he forced the court and the population west to Chang’an and burned palaces and houses. The ruin of the Han capital is historical.
Cao Wei made Luoyang a capital again. Cao Cao died here, and Cao Pi received the abdication here. Sima Yi’s Gaopingling coup also turns on the city gates: the emperor went out to the tombs, and the gates shut behind him. A map of the Three Kingdoms that contains only Chengdu and Jianye misses the city where the Han court broke and where the Wei house lost the state.
