Haisan-Gung

Bayantömöriin Khaisan (Mongolian: Баянтөмөрийн Хайсан), also spelled Khayishan (ᠬᠠᠶᠢᠱᠠᠨ, qayišan) (c. 1862-1917), was one of leading figures of the Outer Mongolian revolution of 1911 for Mongolian independence from China.

Khaisan was born to the Khailtad clan in the Kharchin Right Banner of the Zost League, Qing Dynasty (modern-day Ningcheng County, Chifeng, Inner Mongolia, China). The Zost League bordered Liaoning to the south, from which peasants reclaimed grassland from Zost into productive agricultural fields. In this process, his family became wealthy landowners. He received a well-rounded education and had full command of Mongolian, Manchu and Chinese (and later Russian).

He worked at the banner office of the Kharchin Right Banner. When the Chinese secret society named Jindandao attacked the banner in 1891, he guided the government forces dispatched from Zhili province to suppress the rebels. He also helped his lord Prince Günsennorov modernize Mongol education and military training. In 1900, influenced by the Boxer Rebellion, the remnants of the Jindandao resumed their activity. As a banner official, he crushed some 500 rebels with banner troops.
