 However, under pressure from Turar Ryskulov, a Soviet activist of the Communist International, the city was named "Ulaanbaatar Khot" ("City of Red Hero").In Europe and North America, Ulaanbaatar continued to be generally known as Urga or Khure until 1924, and afterward as Ulan Bator (a spelling derived from , "Ulan-Bator").The Russian spelling ("Улан-Батор") is the Russian phonetic equivalent of the Mongolian name, according to Russian spelling conventions.
