Shidur

Shidur, also written Shidür, was a Yuan Mongol prince, the great-grandson of Qasar and grandson of Yesüngge. He inherited Yesüngge's appanage of pastures around the Argun and Hailar rivers and Hulun Lake.

In 1287 he answered Nayan's rebellion in Liaodong, in league with Qadan and in touch with Kaidu. Yuan forces under Prince Ayači and the Liaodong pacification commissioner Dachu defeated him; he surrendered and confessed, and Kublai Khan spared his life, though one account says he was executed.
