Who was the member of the Manchu Aisin Gioro clan that became the nominal but powerless head of state of Manchukuo?
Politics of Manchukuo Manchukuo was a puppet state set up by the Empire of Japan in Manchuria which existed from 1931 to 1945. The Manchukuo regime was established four months after the Japanese withdrawal from Shanghai with Puyi as the nominal but powerless head of state to add some semblance of legitimacy, as he was a former emperor and an ethnic Manchu.
Emperor Aizong of Jin Emperor Aizong of Jin (25 September 1198 – 9 February 1234), personal name Ningjiasu, sinicised names Wanyan Shouxu and Wanyan Shouli, was the ninth emperor of the Jurchen-led Jin dynasty, which ruled most of northern China between the 12th and 13th centuries. He was considered an able emperor who made several reforms beneficial to the Jin dynasty, such as the removal of corrupt officials and introduction of more lenient tax laws. He also ended the wars against the Southern Song dynasty, and focused the Jin dynasty's military resources on resisting the Mongol invasion. Despite his efforts, the Jin dynasty, already weakened by the flawed policies of his predecessors, eventually fell to the Mongol Empire. He escaped to Caizhou when the Mongols besieged Bianjing, the Jin capital, in 1232. When Caizhou also came under Mongol attack in 1234, he passed the throne to his army marshal Wanyan Chenglin and then committed suicide by hanging himself.
