Ulaanbaatar
Ulaanbaatar has had many names in its history. From 1639 to 1706, it was known as Örgöö (Mongolian: Өргөө, residence), and from 1706 to 1911 as Ikh Khüree (Mongolian: Их = "great", Хүрээ = "camp"), Da Khüree or simply Khüree. Upon independence in 1911,the city's name changed to Niislel Khüree (Mongolian: Нийслэл = "capital", Хүрээ = "camp"). When the city became the capital of the new Mongolian People's Republic in 1924, its name was changed to Ulaanbaatar, literally "red hero", in honour of Mongolia's national hero Damdin Sükhbaatar, that liberated Mongolia from Ungern von Sternberg's troops and Chinese occupation with the Soviet Red Army. In Europe and North America, Ulaanbaatar was generally known as Urga (from Örgöö) or sometimes Kuren (from Khüree) or Kulun (from 庫倫, the Chinese transcription of Khüree) before 1924.
