Half-brothers of the emperor, Princes of the blood, sons of Yungong

Zhangzong's father Yungong left sons by more than one wife.

Zhangzong (b. 1168) was the heir to Shizong; his older half-brother Wudubu (b. 1163) was passed over, and the reason is not checked here. Wudubu, who in the likely course (below) comes to the throne long after Zhangzong, is thirty-six in 1200, and the other four are younger or of unknown age. As I understand the Jin (general knowledge, not checked here), its princes hold titles and posts rather than appanages: no land or people of their own, and their power is the court office, the guard command and the clan around them.

As the nearest males of the emperor's own line they are the natural heirs, and their very existence is part of the succession question.

Who he is

Name: Wudubu (Wanyan Xun, b. 1163), Chengqing (Wanyan Cong), Huandu (Wanyan Gui), Wulibu (Wanyan Zan) and Moulianghu (Wanyan Jie)
Title: Princes of the blood, sons of Yungong
Since: n/a
Born: Wudubu 1163 (text of his page and the Yungong page; his infobox says 1160); the others not known
Family: Sons of Yungong (Xianzong) by several women. Wudubu's mother was the Lady Liu, a concubine of Yungong, styled Empress Zhaosheng after death (Xuanzong page). The Yungong page gives Chengqing, Huandu and Wulibu to a Lady Tian and Moulianghu to a Lady Wang.
Confidence: medium

English Wikipedia's Yungong page lists them with posthumous titles: Prince Huizhuang of Yun, Prince Wenjing of Ying, Prince of Huo, Prince Mindao of Wen. Wudubu's own page gives his titles: Duke of Wen (1178), Prince of Feng (1189), Prince of Yi (1196), and later, undated, Prince of Xing and then Prince of Sheng; so on 1 January 1200 he is Prince of Yi unless one of the undated changes came before it. The titles and posts of the other four on 1 January 1200 are not given.

Overlord

Emperor Zhangzong

Allies and rivals

Rivals for the succession: the uncle Yongji, whom the ministers prefer in the likely course (see Prince Yongji of Wei).

How things stand that morning

Alive, titled, and not pinned to any office. None is named heir. In the likely course (below) Wudubu comes to the throne only after the reign of his uncle Yongji and a coup.

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

1213Wudubu (Wanyan Xun) becomes emperor as Xuanzong after Hushahu's coup (1213); he rules until 1224.Depends on: Wei Shao Wang's fall in 1213. Stopped by: A longer reign of Yongji, or Wudubu's death.

Places of note

Zhongdu: The Central Capital.

Where the sources disagree

Wudubu's birth year: the text of English Wikipedia's Xuanzong page and its Yungong page give 18 April 1163; the infobox of the Xuanzong page says 18 April 1160. We use 1163. The pages do not say whether he or another brother was the eldest of Yungong's sons, so we do not call him that.

Evidence: Names and posthumous titles from one English Wikipedia list; Wudubu's pre-accession titles from his own page; the offices of 1200 are not pinned.

On the map: A person or office with no land of its own; the drawing is a marker.
