Decisive battle between the Georgian forces and Jalāl al-Dīn’s Khwarazmean forces in 1227(or 1228). Following the Mongol invasions of Central Asia, Jalāl al-Dīn, the surviving prince of the Khwarazmean empire, led his troops against Georgia in 1226–1226, and ravaged eastern Georgia and sacked Tbilisi. In 1227, the Georgians joined forces with the neighboring Muslim rulers of Rüm and Shaharmens against the invader. However, Jalāl al-Dīn anticipated their moves and intercepted the Georgian forces moving southward near Bolnisi. Outnumbered and without reinforcements, the Georgians and their North Caucasian allies were decisively defeated. This defeat allowed Jalāl al-Dīn to remain in south Caucasia and continue pillaging eastern Georgia for another four years.
