During the Toluid Civil War, Mongolia was controlled by Ariq Böke, a younger brother of Kublai Khan. After Kublai's victory over Ariq Böke, Mongolia was put within the Central Region (腹裏) directly governed by the Central Secretariat at the capital Khanbaliq (Dadu). However, it was shortly occupied by Kaidu, leader of the House of Ögedei and "de facto" khan of the Chagatai Khanate during his war with Kublai Khan, although it was later recovered by the Yuan commander Bayan of the Baarin.
