王守澄
In 820, Emperor Xianzong died suddenly — a death that was commonly believed to have been a murder carried out by the eunuch Chen Hongzhi (陳弘志). After some confusion, in which the powerful eunuch Tutu Chengcui apparently tried to have Li Kuan (whose name had been changed to Li Yun (李惲) by this point) made emperor, several other key eunuchs — Liang Shouqian (梁守謙), Ma Jintan (馬進潭), Liu Chengjie (劉承偕), Wei Yuansu (韋元素), and Wang Shoucheng — had Tutu and Li Yun killed, and they supported Li Heng to be emperor (as Emperor Muzong). Emperor Muzong honored Consort Guo as empress dowager. (Another son of Emperor Xianzong's, Li Yi, would later suspect Consort Guo and Li Heng of being complicit in Emperor Xianzong's murder, although there was no particular evidence linking either to the murder.)
