Emperor Shang of Han

Emperor Shang of Han (Chinese: 漢殤帝; pinyin: Hàn Shāng Dì; Wade–Giles: Han Shang-ti; early 105 – August or September 106) was an infant emperor of the Chinese Han Dynasty and the fifth emperor of the Eastern Han.

The Empress Dowager Deng placed him on the throne when he was barely over 100 days old, despite his having an older brother, Liu Sheng (劉勝), whose age was unknown but was likely to be young as well.

Empress Dowager Deng also kept Liu Hu (劉祜), the twelve-year-old cousin of Shangdi and future Emperor An of Han in the capital Luoyang as insurance against the baby emperor's death. Liu Hu ascended to the throne when Emperor Shang died in August or September 106; however, Dowager Deng still remained as the regent for the teenager Emperor An. A decree by Empress Dowager Deng during this reign shed light on bureaucratic inefficiency.

Then-Prince Long was born in autumn 105 to Emperor He and a concubine whose identity is unknown. Because Emperor He had, during his reign, frequently lost sons due to illnesses in childhood, according to the superstitions of the time, both Prince Long and his older brother Prince Sheng were given to foster parents outside the palace to nurture.

When Emperor He died early 106, his wife, Empress Deng Sui, retrieved the young princes back to the palace. Prince Sheng was older but regarded as frequently ill and unfit for the throne, for Empress Deng first created the infant Prince Long crown prince. The same night, he was proclaimed emperor. Empress Deng became empress dowager.
