The Bogd Gegen lost his power when Chinese troops occupied the country in 1919. The Tusiyetu Khan Aimak's Prince Darchin Ch'in Wang was a supporter of Chinese rule while his younger brother Tsewang was a supporter of Ungern-Sternberg. When Baron Ungern's forces failed to seize Urga in late 1920, the Bogd was placed under house arrest; then he was freed and reinstated by Ungern shortly before he took Urga in 1921. After the revolution in 1921 led by Damdin Sükhbaatar, the Bogd Khan was allowed to stay on the throne in a limited monarchy until his death in 1924, a year after that of his wife.
