The Battle of Ganja or Elisavetpol (also Elizabethpol, Yelisavetpol, &c.) took place on 25 September 1826/13 September 1826, during the Russo-Persian War of 1826–1828.
Crown prince and commander-in-chief Abbas Mirza had launched a successful campaign in the summer of 1826, which resulted in the recapture of many of the territories that were lost to the Russians by virtue of the Treaty of Gulistan (1813). Noticing the approach of the Iranian army, many of the locals that had recently come under formal Russian jurisdiction, quickly switched sides. Amongst the swiftly recaptured territories by the Iranians were the important cities of Baku, Lankaran and Quba.
