 Although the Avars had pledged their support to Muhammad II of Khwarezm (reigned 1200-1220) in his struggle against the Mongols, there is no documentation for the Mongol invasion of the Avar lands.As historical clues are so scarce, it is probably fruitless to speculate whether the Avars were the agents of the Mongol influence in the Caucasus and whether they were entrusted with the task of levying tribute for the khan, as modern historian Murad Magomedov suggests.The Golden Horde overran the region in 1241, but by the 14th century newly established Avar Khanate managed maintain independence from the Mongols.
