Geopolitics & Diplomacy

- Fearing reprisals should the young Emperor Houshao and his brothers reach adulthood, the conspirators deny that Emperor Hui was the father of Houshao and his brothers. They overthrow the emperor, and despite the imperial pedigree of Liu Xiang as the son of the eldest son of Gaozu of Han, they eventually agree to elevate Gaozu's oldest surviving son, Emperor Wen, to the throne. After being evicted from the palace, Houshao is executed later in the year.source
