Abbas Mirza §

Qajar crown prince, governor of Azerbaijan and the principal Persian commander in the wars against Russia. Abbas Mirza was a military reformer who attempted to modernise Qajar forces after earlier defeats, but he could not prevent Russia from taking the khanates north of the Aras. His defeat in the 1826–28 war led to the Treaty of Turkmenchay, a legal rupture that fixed the Aras as a durable imperial border and separated Persian-ruled Armenians and Turkic-speaking Muslims from the Russian-ruled Caucasus. For Armenian history, his significance lies in the treaty that enabled large-scale Armenian migration into Russian territory. For Azerbaijani and Iranian history, he represents a lost reformist possibility and the trauma of partition. The same defeat thus became Armenian opportunity, Azerbaijani dislocation and Iranian imperial loss.
