مونكو خان
In 1248 Batu sent Berke, along with his brother Tukh-timur, to Mongolia in order to install Möngke Khan on the throne of Great Khan. When he arrived, he invited the Chagatai and Ogedeyd families several times. That is why Berke conducted the kurultai in 1251 and had Möngke enthroned. Berke organized everything under strict conditions.
