Qian Hongzun (錢弘僔) (925[1] – June 7, 940),[2][3] formally Heir Apparent Xiaoxian (孝獻世子, "the filial and wise heir apparent"), was an heir apparent to the throne of the Chinese Five Dynasties and Ten Kingdoms Period state Wuyue during most of the reign of his father Qian Yuanguan (né Qian Chuanguan, King Wenmu), but did not inherit the throne on account of his predeceasing his father.
He was the fifth son of his father Qian Chuanguan,[1] who then was still serving under his father (Qian Hongzun's grandfather), Wuyue's first king Qian Liu (King Wusu), as the acting military governor (Jiedushi) of Wuyue's two main circuits, Zhenhai (鎮海, headquartered at Wuyue's capital Hang Prefecture (杭州, in modern Hangzhou, Zhejiang)) and Zhendong (鎮東, headquartered in modern Shaoxing, Zhejiang).
Qian Chuanguan took control of the state (and changed his name to Qian Yuanguan), but did not claim the title of king at that time, but only the military governor of Zhenhai and Zhendong, as a vassal to Later Tang of the Central Plains.
[5] Qian Hongzun received the title of deputy military governor of Zhenhai and Zhendong, and military prefect (團練使, Tuanlianshi) of Guo Prefecture (果州, in modern Nanchong, Sichuan — a completely honorary title as Guo was then under the control of Later Shu).
[1] In 937, by which time Later Tang had fallen and Wuyue was a vassal state of Later Jin, Qian Yuanguan assumed the title of king.
