The destruction of Baghdad in 1258 by Hulegu Khan alienated Berke Khan of the Golden Horde, a Muslim convert. The concurrent Toluid Civil War split Mongol loyalties: Kublai Khan allied with Hulegu, while Ariq Böke sided with Berke. The Mamluk victory at the Battle of Ain Jalut forced Hulegu to withdraw from Mongolia, emboldening Berke to launch an invasion of the Ilkhanate.
The Berke–Hulegu war was fought between the Golden Horde under Berke Khan and the Ilkhanate under Hulegu Khan, primarily in the Caucasus Mountains during the 1260s. It was the first major military conflict between two Mongol successor states, overlapping with the broader Toluid Civil War dividing the Mongol Empire.
The war contributed significantly to the fragmentation of the Mongol Empire following the death of Möngke Khan, the fourth Great Khan. Together with the Toluid Civil War and the later Kaidu–Kublai war, it marked a turning point from unified Mongol rule toward a system of rival, independent khanates.
