Yang You
emperor of the Sui Dynasty

Yang You, also known by his posthumous name as the Emperor Gong of Sui (隋恭帝) (605 – 14 September 619?), was the last emperor of the Chinese Sui dynasty. He was installed as a puppet emperor by Li Yuan. After Li Yuan founded the Tang dynasty, he had Yang You executed.
Following Yang You's death, his brother Yang Tong claimed the Sui throne until 619.
Li Yuan had rebelled against the rule of Yang You's grandfather Emperor Yang of Sui in 617 and captured the Sui capital Chang'an later that year, seizing Yang You and installing him as a puppet emperor. However, only the commanderies under Li Yuan's control recognized Yang You as emperor. The rest of the commanderies continued to recognize Emperor Yang of Sui as emperor. In 618, after news arrived that Emperor Yang had been killed by the general Yuwen Huaji, Li Yuan had the young emperor yield the throne to him. Li Yuan then murdered Yang You a year later.
During Emperor Yang's reign
Yang You was born in 605, as a son of Yang Zhao, the son and crown prince of Emperor Yang.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Yang You”, the useful work is to connect “emperor of the Sui Dynasty” to the records capable of establishing context and consequence.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q7420. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
