The creation of the Republic of Aras was in response to a border proposal by Sir John Oliver Wardrop, British Chief Commissioner in the South Caucasus, that would have assigned the area to the Armenian Republic.[1] Its existence was ended when troops from the First Republic of Armenia advanced into the region and succeeded in taking control over it in mid-June 1919 during the Aras War. However, this triggered an advance into the Nakhichevan region by the army of the Azerbaijan Republic and Ottoman Empire, and by the end of July Armenia had lost control of the region.[2]
