Gegeen Khan, Emperor Yingzong of Yuan (b. 1303)
Gegeen Khan (Chinese: 格堅汗; Mongolian: Шидэбал Гэгээн хаан, Shidebal Gegegen qaγan; Mongol script: ᠰᠢᠳᠡᠪᠠᠯᠠ ᠭᠡᠭᠡᠨ ᠬᠠᠭᠠᠨ (rotated 90°)), born Shidibala, also known by the temple name Yingzong (Emperor Yingzong of Yuan, Chinese: 元英宗, February 22, 1302 – September 4, 1323), was an emperor of the Yuan dynasty of China. Apart from Emperor of China, he is regarded as the ninth Great Khan of the Mongol Empire, although it was only nominal due to the division of the empire. His name means "enlightened/bright khan" in the Mongolian language.
Early in his short reign, the Khunggirat faction played a key role in the Yuan court. When his grandmother Dagi (Targi) and the grand councillor Temuder died in 1322, his opponents seemed to have triumphed. Despite the Emperor's aim to reform the government based on the Confucian principles, Temuder's faction linked up with the Alan guard and assassinated the emperor in 1323. This was the first violent transition struggle in the Mongolian imperial history, which is also known as Coup d'état at Nanpo, that the Non-Borjigins overthrew the Emperor.
