same years, also 1229-1233, the North Caucasus also became involved in hostilities. Among the rebellious peoples, after the deaths of Jochi and Genghis Khan, the sources mention the Alans and Circassians. And the Hungarian traveler Julian, who visited Alania in 1235, testifies not only to the feudal fragmentation of the region, but also to the fact that, in anticipation of an attack by the Mongols, even on haymaking, plowing or chopping firewood, the Alans “all pull together and armed." By this time the Horde had managed to scatter the Polovtsians in all directions and depopulate the Cis-Caucasian steppes. The same Julian who traveled west from the Sea of Azov along the Ciscaucasia for 13 days found neither “neither man nor house” there until he reached Alania. Main Mongol invasion Background In 1236, Ögedei Khan sent Batu Khan, Güyük, Büri and Möngke Khan together with an army counting more than 200,000 to help Subutai in conquering the rebellious Eastern European as well as North Caucasian nations. Among the mentioned rebellious nations were the Circassians, Alans, Russians and others. Prelude In 1237, the Mongol invasion of Circassia began, during which the Mongols destroyed settlements and ravaged the entire country. Meanwhile, Subutai, along with other Mongol commanders was sent into "The land of the Ases" (Alania and Durdzuketi).

Start of the Mongol campaign After the successful invasion of Zichia, in winter of 1238, the Mongols continued east, reaching the Kingdom of Alania. After ravaging the country sides for exactly on year, the Mongols, in November of 1238, reached the capital of Alania, Maghas, afterwhich Khasi I ordered the withdrawal of troops in Circassia led by Khour to defend the city. Having occupied the western parts of the Terek, Mongol troops, led by Subutai, Kadan, Büri and Möngke Khan also began arriving at
