In 1920-21 the only "solution" to this dispute could come either by military victory—as basically happened in Anatolia, Zangezur and Nakhchivan—or by the imposition from above of a new structure by an imperial power. After the British failed to impose a settlement, the imperial arbiters turned out to be the Bolsheviks, whose 11th Army conquered Karabakh in May 1920.
