Darvaz (region)
Darvaz (, "Darvoz"; , "Darvāz" ), alternatively spelt Darwaz, Darvoz, or Darwoz, was an independent principality until the 19th century, ruled by a mir and its capital was at Kalai-Khumb. The kingdom controlled territory on the left and right banks of the Oxus River. In 1878 Darvaz was invaded by neighboring Bukhara and absorbed into the Bukharan Emirate. In 1895 the left bank of Darvaz was transferred to Afghanistan as part of a border agreement. In the 1920s the portion of Darvaz located in the Tajik Soviet Socialist Republic in the Soviet Union was assigned to the Gharm Oblast. When the Gharm Oblast was dissolved in 1955, Darvaz became part of the Gorno-Badakhshan Autonomous Oblast.
