Outer Mongolia (Mongolian: [Gadagadu Monggol] in Mongolian script, and [Gadaad Mongol] in Mongolian Cyrillic; ) was a territory of the Manchu-led Qing dynasty. Its area was roughly equivalent to that of the modern state of Mongolia, which is sometimes erroneously called "Outer Mongolia" today, plus the Russian republic of Tuva. There was and is some confusion about whether Outer Mongolia only consisted of the four Khalkha aimags (Setsen Khan Aimag, Tüsheet Khan Aimag, Sain Noyon Khan Aimag and Zasagt Khan Aimag), or of Khalkha plus Oirat areas Khovd and Tannu Uriankhai.
